Can you identify which LLM wrote a passage from the text alone? 👀 Each AI lab leaves behind distinct stylistic markers in vocabulary, phrasing, and punctuation. In Name That LLM, you'll identify which of 18 leading models from 6 organizations (Anthropic, Google, Moonshot AI, OpenAI, Qwen, and ZAI) wrote each unlabeled passage. 💰 Prize Pool: $50,000 ⏰ Entry Deadline: January 6, 2027

We're releasing Voice of Reason, a speech-native model that does math out loud. Give it a spoken problem without transcription nor text LLM in the loop, and it reasons and answers in speech. GSM8K goes from 27.3% for GLM-4-Voice to 77.1%. Link in 🧵

Jev-as-a-judge🤝 RL Environment Verifiers 🤝 way cheaper + faster RL a lot of things in Agent World look like classification problems…including grading RL - many RL Tasks need a judge to verify pieces of outputs or trajectories - at scale this can be very expensive and slow with tons of rollouts to score - Jev is incredibly fast and cheap meaning, can potentially remove the verification bottleneck for many tasks we previously worked with @harvey on their LAB benchmark which used LLM-as-Judge for tens of criteria per task we found that Harness/Prompt Engineering + Open Models meant we could judge tasks orders of magnitude cheaper like any verifier, it needs to be calibrated to make you’re giving back a good signal but Jev has the opportunity to massively bring down verification costs (and tuning friction) for many tasks which means more teams will do RL, which is great!

We tested Jev against LLM judges on accuracy, repeatability, latency, and cost to see whether System One models could offer a new approach to agent evaluation.

現状のAI開発競争は、どの方向に転がっても世界がメチャクチャになる可能性は高く、 ・うまくいきすぎる→AIが制御しきれず暴走エンド、AI大規模失業(アメリカでは既に反対運動発生) ・うまくいかない→加熱しすぎたAI投資が吹っ飛んで金融危機 だったので減速案の動機は実はかなり大きい

We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics. The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra. The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.

UTMOSが外国語訛りの強い音声ほど低く評価するという発見から、そもそも人間は外国語訛り音声の自然性を適切に評価できるのか?というのを分析しました 本日午後のポスターセッションで発表します。ぜひご議論ください🙇‍♀️ #asj2026a
