INTENT FACTORED FOR THE WIN! Good science that works always finds a way #ifftw we're going to NeurIPS. Fresh, improved and updated IFG paper dropping soon 👀
Unlock real diversity in your LLM! 🚀 LLM outputs can be boring and repetitive. Today, we release Intent Factored Generation (IFG) to: - Sample conceptually diverse outputs💡 - Improve performance on math and code reasoning tasks🤔 - Get more engaging conversational agents 🤖

We are releasing our first model, Flint, a best-in-class local OSS coding model that runs at 150+ tokens/s on an @nvidia DGX Spark and 125+ tokens/s on a MacBook Pro M4—developed from scratch in less than four months with help from @Recursive_SI's autoresearch system.
Introducing Flint, @Recursive_SI’s first model: a fast local coding model built with our automated research system, the Eureka Machine. • Best-in-class fast local coding • Up to 2x faster than comparable models: 125+ tokens/sec on a MacBook Pro, 150+ on RTX Spark • Built from scratch in under 4 months Private, unmetered intelligence on your own machine. Open weights available now on @huggingface, run it locally on your favorite framework or try it for free on @opencode or @pidotdev.

Knowing when to stop is one of the most important questions of our time
A looped transformer has to know when to stop, and its state has to stay bounded while it loops. We introduce Spherical Fixed-Point Reasoners (SFPRM) 🌐: loop on the unit sphere, where each step is an angle, and stop once the angle is small enough. 🧵 (1/9)

The loop routine becomes 4 steps on the sphere: 1. Spherical linear interpolate (Slerp) a fraction toward the input 2. Apply the nGPT blocks 3. Rotate a fraction toward the proposal 4. Halt once the angle between state and proposal is below some threshold for every token. (3/9)

A groundbreaking Frontier result! @maxencefaldor and @robertarail did a phenomenal job in showing the Argon capabilities so effectively. What a model and what a team in every sense of the word!
Four Gemini 4 Argon agents, one shared Minecraft world, one goal: defeat the Ender Dragon. 27 hours and 2,783 self-written programs later, the dragon fell.

Four Gemini 4 Argon agents teamed up in Minecraft to defeat the Ender Dragon in 27 hours, writing every move as code and coordinating in the game's chat. Great work led by @maxencefaldor with Satinder Singh. Read more in our technical report: arxiv.org/pdf/2610.22319.

Will soon release new methods to better describe motion and instantaneous change. Finalizing notation atm
📈 ignore the empiricists and come check out our linear models

Experts doubted a small neural net could beat Craftax without an LLM's knowledge. ​ Our agent meta-harness built one in 3 weeks. The 15M-param agent beats the final boss 44% of the time, costing a cent, and 10 seconds. ​ GPT-6 Astra won 1%, taking 24 hours and $83. 🧵

Ben taught me so much about doing proper research in RL and the ways to debug policy gradients. Glad the Science of RL team and @reflection_ai gets to have this expertise for their models!
Being part of the Science of RL team for Beam has been an absolute privilege. It's been wonderful to learn how the big RL sausage gets made over the last year and a half and witness the dedication and pace of this team. I look forward to building many more models in the future!

In LLM post-training, policy gradient is "the RL loss". When it fails, we blame the RL: exploration, credit assignment, sampling noise. Image classification has none of these, and the policy gradient is exact. Following it is terrible... ImageNet, 4% vs 62% for cross-entropy.

The critical distinction between base LLMs (2024 and earlier) and modern LRMs is not symbolic tool use. It's the switch from a transductive paradigm (intuit the answer to the query) to an inductive paradigm (intuit the program/instructions that produce the answer to the query). They're trained to be inductive, and they perform test-time induction, i.e. test-time prediction of a NL program / reasoning chain. This unlocks entirely new capabilities -- in particular fluid intelligence. Base LLMs, to this day, have ~0 fluid intelligence. LRMs have substantial levels of fluid intelligence. The performance of LLMs on ARC 1 (a benchmark from 2019) remains ~10-15% today. Scaling them up by a factor ~100,000x got them from 0% to 10%. Meanwhile LRMs the same size or smaller saturated ARC 1 in 2025.
