Yeah, they mogged. First thing I see here, besides insane scores to params ratio (20B is MoE too! 4.25 bpw!), is that they have open sourced their reasoning effort scaling that totally destroys every other attempt. Second thing is that this 120B is trained on *a lot* of tokens. https://x.com/teortaxesTex/status/1952790053241172229
When you’re helping someone build an LLM judge, the goal is to maximize the bits of information you get about a task per unit of human effort/frustration. Our work on ALHF shows that natural language feedback is both information-dense and ergonomic. Check it out in Agent Bricks!”” / X https://x.com/jefrankle/status/1953297527089897944

Evaluation is the hardest problem for physical AI systems: do you crash test cars every time you debug a new FSD build? Traditional game engine (sim 1.0) is an alternative, but it’s not possible to hard-code all edge cases. A neural net-based sim 2.0 is purely programmed by data,”” / X https://x.com/DrJimFan/status/1952755998197948667
ByteDance’s SeedProver scores 331/657 on PutnamBench, almost 4 times the previous SOTA. More impressively, it gets 201/657 under the *light* inference setting, ie equivalent to pass@64-256. DeepSeek-Prover-V2 is just 3 months old… Things go fast now. https://x.com/teortaxesTex/status/1951875052967739787

The OpenAI open weights models are very impressive. These basically beat every model from eight months ago & the small one runs on a laptop. For example, when HLE came out in January, the top score was 3-4%. Been playing with the models and so far they feel like their scores. https://x.com/emollick/status/1952796976279662596

We evaluated the new GPT models with a minimal agent on SWE-bench verified. GPT-5 scores 65%, mini 60%, nano 35%. Still behind Opus 5 (68%), on par with Sonnet 4 (65%). But a lot cheaper, especially mini! Complete cost breakdown + details in 🧵 https://x.com/KLieret/status/1953835750723584357
