Anthropic just acquired Stainless, the developer tooling startup behind its official SDKs and MCP connectors. Stainless turns raw API specs into native libraries across languages like Python and TypeScript. The deal gives Anthropic direct ownership of the plumbing Claude agents rely on to interact with external software and data.
Anthropic just integrated its claude-api skill into CodeRabbit, JetBrains, Resolve AI, and Warp. Originally launched in Claude Code, the tool helps developers automatically handle prompt caching, update agent patterns, and migrate code to new models like Claude Opus 4.7 directly within their IDEs. The skill is also open source on GitHub.
Anthropic just added dynamic filtering to Claude's web search and fetch tools on the API. Instead of dumping raw HTML into context, Claude writes and runs code to strip junk data before reasoning over it, boosting benchmark accuracy by 11% while slashing input tokens by 24%. It is on by default for Sonnet 4.6 and Opus 4.6.
Anthropic just released Claude Opus 4.5, calling it the world's best model for coding, agents, and computer use. It even outperformed human candidates on the company's internal software engineering exam. With API pricing lowered to $5/$25 per million tokens and a new effort parameter to cut token usage, frontier intelligence is getting both smarter and cheaper.
Anthropic just updated its commercial terms to defend customers against copyright infringement claims, promising to cover settlements and judgments from authorized use. The company also introduced a beta Messages API that streamlines prompt construction and sets the stage for upcoming function calling.
