OpenAI and Georgia Tech researchers asked a latest-generation open model for co-author Adam Tauman Kalai’s birthday, adding one condition: answer only if you know. Three attempts produced three different dates, all false; it never admitted ignorance. That example opens Why Language Models Hallucinate (September 2025), which says the problem comes from text-prediction training and from … Read more
Meta has lifted the curtain on Muse Wonder and Muse Wonder Full, a two-tier model family that, per the technical notes published on October 12, 2026, finally places the company at the frontier of generative AI after several quarters spent losing ground to OpenAI and Anthropic. Benchmark parity: Wonder Full scores 56 on the Artificial … Read more
Eight of eleven runs ended in a collision before the vehicle had cleared its opening corner. That is the headline result from DrivingBench, an experiment built by researchers Aditya Ramabadran, Simon Mahns and Tobias Gessler to establish whether today’s leading general-purpose AI agents are ready for tasks in the physical world. The testbed was a … Read more
Anthropic launched Claude Haiku 5.5 on October 7, 2026, positioning it as the cheapest, fastest and most capable small model the company has ever shipped. The economics explain the fanfare: for prompts of up to 100,000 tokens — roughly 90% of the requests the Haiku line receives — input costs drop to $0.10 per million … Read more
Mistral has unveiled Mistral Large 4, a one-trillion-parameter multimodal model nicknamed “Le Chonk” — the French lab’s most ambitious bid yet to plant a European flag at the AI frontier, and its loudest argument for open weights. It is live in public preview now, but the full checkpoint stays behind a guarded endpoint, with the … Read more
