OpenAI is launching two new models, which it says are cut from the same cloth as Astra.

Anthropic’s latest model requires less compute than its predecessor, Opus 5. In its own testing at default settings, the newest model costs 40% less on typical workloads. On top of that, Anthropic is increasing 5-hour usage limits on Pro, Max and Team plans.

British Columbia sued OpenAI and Sam Altman, alleging that ChatGPT reinforced the Tumbler Ridge shooter's violent ideation.
