Mistral AI announced two Devstral updates focused on agentic coding workflows: Devstral Small 1.1 and Devstral Medium. Devstral Small 1.1 remains a 24B Apache 2.0 open model and reaches 53.6% on SWE-Bench Verified. Devstral Medium reaches 61.6%, is available through Mistral’s API, and supports private deployment and custom finetuning for enterprises.
Anthropic introduced Claude Opus 4.8 as an upgrade over Opus 4.7, with stronger benchmark performance across coding, agentic skills, reasoning, and knowledge work. The release also adds dynamic workflows in Claude Code, effort controls in claude.ai and Cowork, and new Messages API support for system entries inside the messages array. Pricing for regular usage remains unchanged, while fast mode is now cheaper than previous models.
