Meta Superintelligence Labs ships Muse Spark, its first frontier model and Meta's first without open weights. Independent testing shows it closing the gap to OpenAI, Anthropic, and Google, but the competition isn't standing still.

Anthropic's new "Claude Managed Agents" gives developers a hosted platform for building and running autonomous AI agents. Early adopters like Notion and Rakuten are already using the system.

OpenAI is restructuring its subscription tiers with a new $100-per-month Pro plan. The biggest change: significantly more Codex usage for heavy users at half the price of the old Pro tier.

A US appeals court has declined to temporarily block the Pentagon's designation of Anthropic as a national security risk, Reuters reports.

Zhipu AI has released its new GLM-5.1 model under an MIT license. The model can reportedly refine its own approach over hundreds of iterations when tackling coding tasks.
