AI prescriptions have arrived!
Today, Nolla Health became the first organization in the U.S. (and possibly the world) to receive regulatory approval for an AI to issue initial prescriptions. This makes Nolla the first ever actual end-to-end AI doctor.

This project was a blast to work on! Here's another cool 1 Trillion X zoom into a fractal from the Equilibrium Reasoners model for Sudoku (plus some more visuals in the thread)
Our group discovered that reasoning models produce fractals when asked to solve hard problems. We can use nonlinear dynamics to probe the thinking processes of recurrent depth models on Sudoku, mathematics, and even ARC-AGI (1/N) arxiv.org/abs/2609.04963

I am very grateful to @unconvAI for supporting my group's work on fractal basins in reasoning models! this proposal is what first inspired us to study reasoning as a dynamical system. looking forward to learning a lot more from the company & the other awardees this year
Unconventional AI was founded on a suspicion: that more parameters and more attention is one path among several, and that the alternatives stay underexplored not because they are less promising but because they are harder to fund. The Unconventional Grant exists to fund those alternatives. We said plainly that we would rather back a well-posed risk than a safe increment. Today we are announcing our first cohort. Five projects, each receiving $100,000: - Thierry Tambe (Stanford) is treating data retention as an architected resource, so processors stop spending area and energy preserving information long after the computation stops needing it. - William Gilpin (UT Austin) is testing whether the slowdown in reasoning models is transient chaos, the same phenomenon that governs turbulent flows, and looking for the fractal traps in latent space that delay convergence. - Logan Wright (Yale) is asking what neural scaling laws become when the neural network is a physical analog machine rather than a digital simulation of one, noise, drift, and energy budgets included. - Yoon Kim (MIT) is pushing looped Transformers past the tens of loops where gains have appeared to saturate, into the hundreds and thousands, with primitives designed to keep parameters on-chip. - Wanyu Lei, Daniel Kunin, and Friedrich T. Sommer (UC Berkeley) are deriving recurrent architectures directly from the mathematics of state updates, on the premise that efficient state tracking is not one capability among many but a foundational design principle. To the five teams: congratulations. Each team describes its own project, in its own words, in the full announcement. unconv.ai/blog/2026-unconven…

AI compute and inference are increasingly $$$. How can we change the unit economics of AI to improve accessibility? It's been fun working with @prlnet to release the first model endpoint that simultaneously generates tokens **and** a digital asset that can subsidize inference! 🪙 Check it out, links below 🚀

Loved working on this project, super proud of it! Thank you @AwesomeBao, @bialjail, and @wgilpin0 for being such a great team that I learned so much from. Excited to share our work at ICML!
Our ICML spotlight paper discovers universal redundancies in time series foundation models: the middle layers of many models can be removed without sacrificing performance 1/

We trained LoRA adapters of different ranks to understand training dynamics, finding that adapters for GSM8k live in a surprisingly vast, low-rank solution space. This hints that some model skills are easy to learn, and training is more forgiving than we think. @hasith_v 1/6 🧵

We post-trained MedGemma to be SoTA in visual medicine ddx, outperforming Opus 4.6, Gemini 3.1 and GPT-5.4 while running at ~1/30th the cost. @nollahealth Part 1 - improving visual reasoning 🧵1/6

How do time series foundation models forecast unseen dynamical systems? In new experiments, we find that small transformers learn to approximate transfer operators in-context. (1/N) arxiv.org/abs/2602.18679

Soooo proud of this one! I'll make a post w more details shortly
What governs the geometry of time and space embeddings in LLMs? We show it follows from translation symmetry in language statistics. With Dhruva Karkada, @DanKorchinski, Andres Nava, @yasamanbb arxiv.org/abs/2602.15029

Great to see high quality software dev in comp bio. It still amazes me how much of computational biology is based on single-thread processing of large .txt files with minimal application-specific-optimization.
Arc bioinformatics scientists @noamteyssier and @a_dobin have just released cyto, an ultra-high throughput processor specifically optimized for @10xGenomics Flex single-cell data. We are excited to make this resource open source: biorxiv.org/content/10.64898…
