Theory of Mind (ToM) is crucial for next gen LLM Agents, yet current benchmarks suffer from multiple shortcomings. Enter 💽 Decrypto, an interactive benchmark for multi-agent reasoning and ToM in LLMs! Work done with @TimonWilli & @j_foerst at @AIatMeta & @FLAIR_Ox 🧵👇

What if you kept asking an LLM to "make it better"? In some recent work at FAIR, we investigate how we can efficiently use RL to fine-tune LLMs to iteratively self-improve on their previous solutions at inference-time. Training for iterated self-improvement can be costly. The

I’m a psychiatrist. In 2025, I’ve seen 12 people hospitalized after losing touch with reality because of AI. Online, I’m seeing the same pattern. Here’s what “AI psychosis” looks like, and why it’s spreading fast: 🧵

We discovered alien intelligence in sand, and can now play its dreams in real time with a mouse and keyboard. Congrats to the team! Now, can it run Doom? 🤔

Games isolate key aspects of intelligence and make for fantastic evergreen benchmarks. Thrilled to see them come back in style! And if you're excited about LLM Theory of Mind, how about a game of Decrypto with your favourite LLM? 👀👇

Sloppy authors write sloppy reviews. Conferences should publish rejection rates for first and last authors. This cuts down the number of submission, improves submission quality, and limits the number of sloppy authors being forced to review. Make this retroactive, too!🧹

Scaling AI research agents is key to tackling some of the toughest challenges in the field. But what's required to scale effectively? It turns out that simply throwing more compute at the problem isn't enough. We break down an agent into four fundamental components that shape

Antiviral therapy design is myopic 🦠🙈 optimised only for the current strain. That's why you need a different Flu vaccine every year! Our #ICML2025 paper ADIOS proposes "shaper therapies" that steer viral evolution in our favour & remain effective. Work done @FLAIR_Ox 🧵👇

Recently, there has been a lot of talk of LLM agents automating ML research itself. If Llama 5 can create Llama 6, then surely the singularity is just around the corner. How can we get a pulse check on whether current LLMs are capable of driving this kind of total

Most AI labs don't try to build AI for normal people. They try to build the AI that will build AI for normal people (and for everything else). Which isn't to say that memory isn't important.

seems big AI labs are hyperfixating on reasoning when they should focus on *memory* instead normal people won't use models that can think for hours to solve hard math problems people want models that learn over time, remember details, adapt and interact like a person would

Very cool LLM benchmark based on the game - Decrypto. It shows some surprising shortcomings of the current LLM models. But what's even cooler is that it allows us to analyse the Theory of Mind of LLMs, definitely check it out! Congrats to the authors 🎉

Much-needed multi-agent benchmark for LLMs 👥 Theory of Mind is key as LLMs act in agentic, interactive settings — yet remains underexplored and hard to measure. 💽 Decrypto offers an ToM-based evaluation of reasoning for agents operating in complex social settings. Great work!
