French AI lab Mistral has launched Mistral Large 4, a 1.05-trillion-parameter natively multimodal model the company has nicknamed "le Chonk," now available in public preview via API. Open weights are promised by the end of October, after a red-teaming phase.

Anthropic released Claude Haiku 5.5 on Wednesday, the third launch in the Claude 5.5 family after Opus 5.5 and Sonnet 5.5 earlier this fall. Where the bigger siblings brought capability, Haiku 5.5 brings aggression: Anthropic calls it the cheapest, fastest, and most capable small model it has ever shipped, and the pricing backs up the claim.
