Hey PaperLedge learning crew, Ernis here, ready to dive into some fascinating research! Today, we're tackling a paper all about how we can make those super-smart Large Language Models, or LLMs, even more useful by teaching them how to use...tools! Think of it like giving your brain access to a whole workshop of gadgets and gizmos.
Now, you know how LLMs like ChatGPT are great at answering questions, writing stories, and even coding? Well, this paper asks: what if we could give them the ability to go outside their internal knowledge base and use external tools to get even better answers?
The problem is, current methods for teaching LLMs to use tools often require retraining the model every time you want it to learn a new tool – a bit like having to rewrite the entire operating system of your computer just to install a new app! Or, they rely on feeding the model tons of examples of how to use each tool, which can be slow and inefficient.
That's where this research comes in. These researchers have developed a clever new approach called "Chain-of-Tools."
Here's the gist: Imagine you're trying to assemble a piece of IKEA furniture. Instead of just staring at the instructions and hoping for the best, you methodically go through each step, selecting the right tool for the job – screwdriver, Allen wrench, hammer – and using them in the correct order. That’s kind of what Chain-of-Tools does.
The key is that it leverages the LLM's already amazing understanding of language to figure out which tool is best for which step in solving a problem. And the really cool part? It can do this even with tools it's never seen before! It's like being able to pick up a brand new, oddly shaped tool and figure out what it's for just by looking at it and understanding its purpose.
To test their method, the researchers created a new dataset called "SimpleToolQuestions". This dataset is packed with tricky questions that require the LLM to use different tools, including tools the LLM hasn't encountered during training. They then put Chain-of-Tools to the test on different kinds of problems:
Numerical Reasoning: Questions that require math and calculations (like those pesky word problems we all hated in school).
Knowledge-Based Question Answering: Questions that require accessing and combining information from different sources.
And guess what? Chain-of-Tools outperformed other methods, especially when dealing with unseen tools! The researchers also identified which aspects of the LLM's reasoning were most important for successfully choosing the right tools.
Why does this matter?
For developers: This research offers a more efficient and flexible way to equip LLMs with tool-using abilities, opening the door to a wider range of applications.
For businesses: Imagine LLMs that can automatically access and analyze data from various sources, streamline workflows, and make smarter decisions.
For everyone: As LLMs become more integrated into our lives, this kind of research helps ensure they are powerful, adaptable, and ultimately, more helpful.
So, what are the big takeaways? Well, it seems like we're getting closer to a future where LLMs can seamlessly integrate external tools into their problem-solving process, unlocking a whole new level of capability. But it also raises some interesting questions:
How do we ensure that LLMs are using these tools responsibly and ethically? What kind of guardrails do we need to put in place?
As LLMs become more reliant on external tools, how do we prevent them from becoming overly dependent on them, potentially hindering their own internal reasoning abilities?
Could this approach be used to teach LLMs more complex skills, like scientific research or even creative endeavors?
Food for thought, learning crew! You can find the code and data for this research on GitHub (link in the show notes). I'm excited to see where this research leads us. Until next time, keep exploring!Credit to Paper authors: Mengsong Wu, Tong Zhu, Han Han, Xiang Zhang, Wenbiao Shao, Wenliang Chen

Artificial Intelligence - Why Do Multi-Agent LLM Systems Fail?
Monday Mar 24, 2025
Monday Mar 24, 2025
Hey everyone, Ernis here, and welcome back to PaperLedge! Today, we're diving into some fascinating research about something that sounds straight out of a sci-fi movie: multi-agent systems using large language models, or LLMs.
Think of it like this: instead of just one super-smart AI trying to solve a problem, you've got a team of AI agents, each with its own role, working together. Sounds amazing, right? Like the Avengers, but with algorithms! But here's the thing: while everyone's excited about the potential of these AI teams, the actual results in solving complex tasks... haven't quite lived up to the hype.
That's where this paper comes in. Researchers dug deep to figure out why these AI teams aren't performing as well as we'd hoped compared to just a single, really good AI. It's like having a soccer team full of talented players who just can't seem to coordinate and score goals as effectively as one star player who does everything themselves.
So, what did they do? They looked at five popular AI team frameworks and put them through their paces on over 150 tasks. And to make sure they weren't just seeing things, they had six human experts painstakingly analyze what went wrong.
This wasn't just a quick glance. Three experts would look at each task result, and if they mostly agreed on why the AI team failed, that failure mode was noted. In fact, they agreed so much that they earned a Cohen's Kappa score of 0.88, which is a measure of how reliable their agreement was.
What they found was a treasure trove of insights. They identified 14 unique ways these AI teams can stumble and categorized them into three broad areas:
Specification and System Design Failures: This is like the architect forgetting to include a crucial support beam in the building plans. If the initial setup is flawed, the whole system is doomed from the start.
Inter-Agent Misalignment: Imagine a group project where everyone's working on a different part, but nobody's communicating effectively. This is where the AI agents aren't on the same page, leading to conflicts and inefficiencies.
Task Verification and Termination: This is about knowing when the task is actually done, and done correctly. It's like submitting a report without proofreading it – it might look finished, but it's full of errors.
To make this kind of analysis easier in the future, they even created a system called MASFT that uses another LLM to act as a judge, helping to scale up the evaluation process. Pretty cool, right?
Now, here's where it gets really interesting. The researchers wondered if these AI team failures were easily fixable. Could simply giving the agents clearer roles or improving how they coordinate solve the problems? The answer, surprisingly, was no. They found that the issues were often much deeper and require more complex solutions.
This is like finding out that a struggling sports team doesn't just need a pep talk; they need a complete overhaul of their training methods and team dynamics.
The good news is that this research provides a clear roadmap for future work. By understanding exactly where these AI teams are failing, we can start developing better frameworks and strategies to unlock their full potential.
And the best part? They've open-sourced their dataset and LLM annotator, meaning other researchers can build on their work and accelerate progress in this exciting field.
So, why does this research matter? Well, for:
AI Researchers: This paper provides a valuable framework for analyzing and improving multi-agent systems.
Businesses: Imagine using AI teams to tackle complex problems in finance, healthcare, or logistics. Understanding these failure modes can save time, money, and resources.
Everyone Else: As AI becomes more integrated into our lives, understanding its limitations and potential is crucial. This research helps us manage expectations and encourages responsible development.
As the researchers note, fixing these failures requires more complex solutions, highlighting a clear roadmap for future research.
This research highlights that getting AI to work well together is much harder than we expected.
Here are a couple of thought-provoking questions that popped into my head:
Could we use these identified failure modes to train AI agents to be better teammates?
Are there certain types of tasks where single-agent systems will always be superior to multi-agent systems?
That's all for this episode of PaperLedge! I hope you found this breakdown of multi-agent system challenges insightful. Until next time, keep learning!Credit to Paper authors: Mert Cemri, Melissa Z.

Monday Mar 24, 2025
Hey everyone, Ernis here, and welcome back to PaperLedge! Today, we're diving into a fascinating paper about how well AI models, specifically those code-generating whizzes, really understand the code they're creating. Think of it like this: you can write a recipe that tastes amazing, but do you understand why it works, or how to make it efficiently for a huge party?
That’s where BigO(Bench) comes in. This paper introduces a new coding benchmark, essentially a test, specifically designed to see if these AI models can grasp the idea of computational complexity. What is computational complexity, you ask? Think of it as how much time and space (like memory) a computer program needs to run, especially as the problem it's solving gets bigger. We measure these using "Big O" notation.
It's like this: imagine you're searching for a specific name in a phone book. If the phone book isn't sorted, you might have to look at every single name (that's like O(n), where 'n' is the number of names). But if the book is sorted alphabetically, you can use a "binary search" – cutting the book in half each time – which is much faster (that's like O(log n)). Big O notation tells us how the time it takes to search grows as the size of the phone book increases.
The problem is, existing tests for AI code generators often overlook whether they can create code that is efficient in terms of time and space. They might write functional code, but is it the best way to solve the problem, especially when dealing with large amounts of data?
So, what makes BigO(Bench) special?
It includes a tool that can figure out the algorithmic complexity of any Python code, whether written by a human or an AI. Think of it like a built-in efficiency expert!
It's got a massive dataset of coding problems – over 3,000! – and over a million solutions, all tagged with their time and space complexity. These are solutions from real coding contests, annotated with the "Big O" labels, as well as performance data.
The researchers then put several state-of-the-art AI models through the BigO(Bench) test. And the results were… interesting!
Here's the key takeaway: the AI models that are really good at generating code (what the paper calls "token-space reasoning models") aren't necessarily good at understanding complexity. They can write code that works, but they may not understand why some solutions are much more efficient than others. It's like being able to assemble a car without understanding how the engine actually works.
“Token-space reasoning models are unrivaled in code generation but not in complexity understanding, hinting that they may not generalize well to tasks for which no reward was given at training time.”
The paper suggests that these models might struggle with tasks where they haven't been specifically trained to optimize for efficiency. They're good at mimicking patterns they've seen, but they don't necessarily understand the underlying principles of algorithmic complexity.
So, why does this matter? Well, for a few reasons:
For Developers: It highlights the limitations of current AI code generators. You can't just blindly trust them to write the most efficient code. You still need human expertise to review and optimize their output.
For AI Researchers: It points to a crucial area for improvement. We need to develop AI models that can not only generate code but also reason about its efficiency and scalability.
For Everyone: As AI becomes more integrated into our lives, understanding its limitations is crucial. This paper reminds us that AI is a tool, and like any tool, it has strengths and weaknesses.
This BigO(Bench) benchmark is a step in the right direction, helping us understand how well AI models truly "get" code, and paving the way for more efficient and reliable AI-powered coding tools.
Now, this all brings up some interesting questions for our discussion. For instance:
Given these findings, how should software development teams incorporate AI code generators into their workflows responsibly?
Could we train AI models to better understand complexity by giving them "rewards" for writing more efficient code? How would we even design such a reward system?
Does this research change your perspective on the future of AI in software engineering? Are we further away, or closer than we thought, to truly "intelligent" coding assistants?

Monday Mar 24, 2025
Hey PaperLedge learning crew, Ernis here, ready to dive into some seriously cool tech that could make our AI overlords (just kidding… mostly!) a whole lot faster.
Today we're talking about a research paper that's all about making those massive Language Models, the brains behind things like ChatGPT, learn and think way quicker. Think of it like this: imagine you're trying to pack a suitcase. Instead of cramming everything in randomly, what if you could magically make some of the clothes disappear without losing any outfits? That’s kind of what this paper’s doing with AI!
See, these huge AI models have these things called "activations," which are like little switches that turn on and off as the model learns. These activations do a lot of math. The researchers found a smart way to "thin out" these activations using something called "2:4 sparsity." Sounds complicated, right? But basically, it means that for every four numbers, they only keep the two most important ones. It's like only keeping the two ingredients that really make your grandma's secret sauce special.
But here's the kicker: they’re doing this thinning out specifically with a type of activation called "Squared-ReLU," and it turns out these activations have a natural tendency to be sparse already! It’s like finding out that half your suitcase is already empty! This means the researchers can make the activations smaller without messing up the AI's performance. No lost outfits!
So, what does this mean in practice? Well, they found that by using this "2:4 sparsity" trick, they could speed up a crucial part of the AI model called the "Feed Forward Network" (FFN) by up to 1.3 times! That's a pretty significant boost. It's like getting a 30% discount on the time it takes to train or use one of these models. And get this, it works both when the AI is learning (training) and when it's actually being used (inference)!
Think of it like teaching a dog a new trick. If you can make the training process faster, you can teach the dog more tricks in the same amount of time. And if the dog can perform the tricks faster, it's more useful overall!
This has huge implications for anyone working with large language models. Whether you're a researcher trying to build the next generation of AI, a business trying to use AI to improve your services, or just someone who's curious about how these things work, this research shows that sparsity is a really promising way to make AI faster and more efficient.
"This work highlights the potential for sparsity to play a key role in accelerating large language model training and inference."
So, here are a couple of things that popped into my head while reading this paper:
If this works so well for Squared-ReLU activations, could we find similar "intrinsic sparsity" in other types of AI components and apply similar techniques?
While 1.3x speedup is great, what are the limitations? Does this technique work equally well on all kinds of hardware, or are there specific GPUs that benefit the most?
This research is a great reminder that there are still tons of exciting opportunities to improve AI technology, and I'm excited to see what comes next! What do you all think?

Hey everyone, Ernis here, and welcome back to PaperLedge! Today, we're diving into a fascinating paper about how AI, specifically those brainy Large Language Models or LLMs, are learning to code – and how well they’re keeping up with the ever-changing world of programming languages. Think of LLMs as incredibly smart students trying to learn a new language, not Spanish or French, but computer languages like Rust.
Now, Rust is a pretty popular language known for its speed and safety, but it's also a language that evolves really quickly. Imagine trying to learn Spanish, but the grammar rules and vocabulary change every few months! That’s kind of what it's like for these AI models. The problem is, they need to write code that works with the specific version of Rust being used. If they don't, the code might not compile, or worse, it might do something completely unexpected. It's like using an old recipe with ingredients that have been renamed or changed – the cake might not turn out so great.
This paper tackles a big problem: how do we test if these coding AIs are actually good at adapting to these changes? Existing tests aren't cutting it, they are often done manually, which takes forever, and they don't give us enough specific information about which kinds of changes the models struggle with. That's where RustEvo comes in!
So, what exactly is RustEvo? Well, think of it as a dynamic obstacle course designed specifically to test how well AI models can handle changes in the Rust language. The researchers created this framework that automatically generates these programming tasks. It's like having a robot teacher that can create endless variations of quizzes! They synthesized a whole bunch of API changes - these are like the building blocks of Rust code - and turned them into challenges for the AI models. They looked at four main types of changes:
Stabilizations: When something becomes a standard part of the language.
Signature Changes: When the way you write a specific command changes slightly.
Behavioral Changes: When a command does something a little bit differently than it used to. This one is tricky as the code looks the same!
Deprecations: When a command is on its way out and shouldn't be used anymore.
They even made sure the types of changes in RustEvo mirrored the actual distribution of changes that happen in the real world, making the test even more realistic.
So, how did the AI models do on this obstacle course? Well, the results were pretty interesting! The researchers put some of the best AI models out there to the test and found some pretty significant differences in their performance. They were much better at handling stabilized APIs, which makes sense since those are well-documented and widely used. But they struggled a lot more with those behavioral changes – the ones where the code looks the same, but the meaning is different. That’s because the models have a hard time understanding those subtle semantic changes.
"Models achieve a 65.8% average success rate on stabilized APIs but only 38.0% on behavioral changes, highlighting difficulties in detecting semantic shifts without signature alterations."
Another key finding was that the models' knowledge cutoff date really mattered. If a change happened after the model was trained, it performed much worse. It’s like asking a student about a historical event that happened after they finished their history class. They just wouldn't know about it! But the researchers also found a way to help the models out. They used something called Retrieval-Augmented Generation or RAG. Basically, they gave the models access to up-to-date information about the Rust language, and that helped them improve their performance, especially for those changes that happened after their training.
So, why does all of this matter?
For Developers: This research helps us understand the limitations of AI coding assistants and shows us where we need to focus our efforts to improve them.
For AI Researchers: RustEvo provides a valuable tool for evaluating and improving the adaptability of LLMs in dynamic software environments.
For Anyone Interested in the Future of AI: This study highlights the challenges of building AI systems that can keep up with the ever-changing world around them.
The authors argue that evolution-aware benchmarks like RustEvo are crucial for making sure that AI models can truly adapt to the fast-paced world of software development.
And the great news is that they have made RustEvo and the benchmarks publicly available! You can check it out at https://github.com/SYSUSELab/RustEvo.
So, after hearing about RustEvo, a few questions jump to mind:
Could this approach be adapted to other rapidly evolving languages like JavaScript or Python? What would that look like?
How can we better train AI models to understand the intent behind code changes, rather than just memorizing syntax?
Beyond coding, what other areas could benefit from "evolution-aware" benchmarks to test AI adaptability?
That's all for today's episode of PaperLedge. I hope you found this dive into RustEvo as interesting as I did. Until next time, keep learning!Credit to Paper authors: Linxi Liang, Jing Gong, Mingwei Liu, Chong Wang, Guangsheng Ou, Yanlin Wang, Xin Peng, Zibin Zheng

Computer Vision - Enabling Versatile Controls for Video Diffusion Models
Monday Mar 24, 2025
Monday Mar 24, 2025
Hey PaperLedge crew, Ernis here, ready to dive into some seriously cool video tech! Today, we're talking about a new approach to creating videos from text, but with a twist – total control!
So, imagine you're a director. You have a script, but you also want to dictate every little detail: "Okay, I want a cat juggling bowling pins in a park, but make sure the cat's silhouette is super sharp, like a Canny edge drawing, and the bowling pins are clearly separated by color – use a segmentation mask!"
That level of control is what's been missing in a lot of text-to-video AI. Existing systems are good, but they often struggle with the fine-grained details. That's where this paper on VCtrl, or PP-VCtrl, comes in. Think of VCtrl as the ultimate director's toolkit for AI video creation.
What's so special about VCtrl? Well, the researchers built a system that allows you to feed in all sorts of control signals alongside your text prompt. Control signals are things like:
Canny Edges: These are basically outlines, like a coloring book drawing, that tell the AI where the hard lines and shapes should be.
Segmentation Masks: Imagine coloring different objects in a scene with different colors. That's what a segmentation mask does. It helps the AI understand "this area is the cat," "this area is the bowling pin," and so on.
Human Keypoints: These are like those stick figure drawings that show the pose and movement of a person. They let you control how people are moving in the video.
VCtrl can understand all these different control signals and use them to guide the video generation process without messing with the core AI engine that makes the video in the first place.
Think of it like adding accessories to a car. You're not rebuilding the engine, you're just adding a spoiler or new tires to customize the look and performance.
Now, how does VCtrl pull this off? Two key ingredients:
Unified Control Signal Encoding: They've created a single pipeline that can understand all these different types of control signals, from edges to keypoints.
Sparse Residual Connection: This is a fancy term, but basically, it's a way of efficiently feeding the control information into the AI without overwhelming it. It's like giving the AI little nudges in the right direction, rather than a full-blown shove.
The result? The researchers showed that VCtrl not only gives you much more control over the video, but it also improves the overall quality. The videos look sharper, more realistic, and more closely match your creative vision.
So, why does this matter? Well, for:
Filmmakers and Animators: This could be a game-changer for creating storyboards, pre-visualizations, or even entire animated sequences with incredible precision.
Game Developers: Imagine creating realistic character animations or dynamic environments on the fly with detailed control over every aspect.
Anyone Creating Video Content: From social media creators to educators, VCtrl could empower anyone to create engaging and visually stunning videos with ease.
The code and pre-trained models are even available online for you to try out! (Check out the link in the show notes.)
This research really opens up some interesting questions:
How far can we push the boundaries of control? Could we eventually control the lighting, textures, or even the emotions of the characters in the video?
What are the ethical implications of having this level of control over video generation? Could it be used to create deepfakes or manipulate public opinion?
And finally, will AI video generation ever truly replace human creativity, or will it simply become another tool in the artist's toolbox?
These are the questions that keep me up at night, learning crew! Let me know your thoughts in the comments. Until next time, keep learning and keep creating!Credit to Paper authors: Xu Zhang, Hao Zhou, Haoming Qin, Xiaobin Lu, Jiaxing Yan, Guanzhong Wang, Zeyu Chen, Yi Liu

Monday Mar 24, 2025
Alright learning crew, Ernis here, ready to dive into some seriously cool research! Today, we're tackling a paper that's all about finding the absolute best solutions when you've got a bunch of different goals to juggle.
Imagine you're designing a car. You want it to be super fuel-efficient, but also incredibly safe. Those two things often pull in opposite directions, right? A lighter car is usually more fuel-efficient, but a heavier car might be safer in a crash. Finding that perfect balance – the sweet spot where you're getting the best of both worlds – that's what this research is all about.
Now, the researchers are working with something called "offline multi-objective optimization." Let's break that down. "Optimization" just means finding the best solution. "Multi-objective" means you've got more than one goal. And "offline" means you're working with a dataset of designs that already exist. Think of it as having a catalog of car designs and their fuel efficiency and safety ratings.
The core of their idea is a clever combination of two things: a "diffusion model" and a "preference model." The diffusion model is like an artist who starts with random noise and gradually refines it into a beautiful picture. In this case, the "picture" is a new design. The preference model acts like a critic, guiding the artist towards designs that are better in terms of our multiple objectives.
Think of it like this: the diffusion model is trying to bake the perfect cake, but it doesn't know what "perfect" means. The preference model is like a judge who tastes the cake and says, "More sweetness! Less salt!" The diffusion model then tweaks the recipe and tries again, guided by the judge's feedback.
The secret sauce here is how they train the "judge" – the preference model. It's trained to predict whether one design is better than another, using something called "Pareto dominance." That's a fancy way of saying that one design is better if it's at least as good as another in every objective, and strictly better in at least one. So, our judge knows what a "better" cake tastes like.
But here's the coolest part: this preference model can actually figure out what makes a good design even beyond the designs it was trained on! It's like the judge learning what makes a good cake, and then being able to identify a great new cake they've never seen before.
They also added something called "diversity-aware preference guidance." This is crucial. Imagine you're trying to find the best hiking trails. You don't just want the single best trail; you want a range of awesome trails with different views and challenges. That's what diversity-aware guidance does. It ensures that the solutions are not only optimal but also spread out nicely across all the objectives.
"This ensures that generated solutions are optimal and well-distributed across the objective space, a capability absent in prior generative methods..."
So, why does this matter? Well, imagine:
Engineers: They can use this to design better products, from cars and airplanes to bridges and buildings.
Scientists: They can discover new materials or drugs with specific properties.
Business folks: They can optimize their marketing campaigns or supply chains.
Basically, anyone who needs to make decisions with multiple conflicting goals can benefit from this research.
The researchers tested their approach on various problems and found that it consistently outperformed other methods. It's a big step forward in finding those elusive "best of all worlds" solutions.
Here are a couple of things that popped into my head:
Could this approach be used to personalize recommendations? Imagine a music app that recommends songs based not just on your taste, but also on your mood and the time of day.
How well does this work when the objectives are really, really complicated and hard to measure? What happens when the "taste" of the cake is something really subjective and difficult to define?

Hey PaperLedge crew, Ernis here, ready to dive into some fascinating research that could change how we interact with our digital assistants! Today, we're unpacking a paper that tackles a big challenge: making those super-smart AI conversationalists, the ones powered by large language models (LLMs), more efficient and affordable.
Now, these LLMs are like the brains behind a lot of cool stuff, from chatbots that answer almost any question to systems that can summarize long meetings or figure out what you really mean when you ask something. But, and this is a BIG but, they're resource hogs! Think of it like this: imagine you're trying to find a single grain of sand on a beach. LLMs, in their current form, are basically trying to sift through every single grain to find that one special one. That takes a lot of energy and time, right?
This paper proposes a clever solution: a "filter" for conversations. Instead of making the LLM process every single sentence or snippet, this filter figures out which parts are actually important based on the intent behind them. Think of it like having a metal detector that only beeps when it finds gold – you don't waste time digging up bottle caps and rusty nails!
The researchers used a technique called knowledge distillation. Imagine you have a master chef (the LLM) who knows everything about cooking. Knowledge distillation is like learning the key recipes and techniques from that master chef, and then teaching them to a less experienced, but much faster and more efficient, cook (the smaller filter model).
So, how did they build this filter? They created a special dataset of conversations, making sure it was diverse and reflected the kinds of things people actually talk about. Then, they annotated these conversations with the intents behind the different parts. Intent is basically what someone is trying to achieve with their words: are they asking a question? Making a request? Expressing an opinion?
With this labeled data, they fine-tuned a smaller, more efficient model called MobileBERT. This is like taking a Mini Cooper and turning it into a lean, mean, intent-detecting machine! Because MobileBERT is smaller and faster, it can quickly scan through conversations and identify the snippets that are most likely to contain the information the LLM needs.
The beauty of this approach is that by only feeding the relevant snippets to the LLM, they can significantly reduce the overall operational costs.
Why does this matter? Well, for starters, it means we can make AI assistants more accessible to everyone. If running an LLM becomes cheaper, more companies and organizations can afford to use them. It could also lead to more powerful and personalized AI experiences on our phones and other devices, since they won't be draining our batteries so quickly.
But here's where things get really interesting. Think about customer service. Imagine an AI that can quickly identify customer complaints and route them to the right agent, without needing to analyze every single word of the conversation. Or consider medical diagnosis, where an AI could filter out irrelevant information and focus on the key symptoms described by a patient.
This research could have big implications for:
Businesses: Lowering the cost of AI-powered customer service and data analysis.
Consumers: Getting faster and more accurate responses from AI assistants.
Developers: Building more efficient and scalable AI applications.
So, here are a couple of things I'm wondering about after reading this paper:
How well does this filter work with really complex or nuanced conversations, where the intent might be harder to detect?
Could this approach be used to filter out biased or toxic content in conversations, in addition to filtering for intent?
