In a week full of model launches, the most unusual announcement involved no model at all. OpenAI, Anthropic, and Google DeepMind have confirmed they spent several weeks coordinating on AI safety, jointly unveiling cyber-focused AI models, safeguards, and access programs developed collaboratively across the three labs. One report describes a formally announced joint standards body publishing common testing protocols for frontier models.

OpenAI's "28 Days of Continuous Releases" stunt hit Day 3 with its biggest consumer move yet: the GPT-6 model series is now rolling out globally to every ChatGPT user, free and paid. Plus and Team subscribers get GPT-6 Sol, while free and Go users will see GPT-5.6 gradually replaced by GPT-6 Luna. Alongside the rollout, OpenAI says Codex and Work weekly active users have passed 40 million, with usage quotas reset across the board.
