The most capable AI models of their time, usually built by a handful of large labs at great cost.
Rules and safety commitments often target frontier models specifically, because new risks are expected to appear there first.
The filing also says Anthropic does not expect to let Claude design successive frontier models without meaningful human oversight.
Access is limited for now, with broader availability to follow once guardrails are refined.
Training without live internet access puts the focus on containment, and OpenAI has not said what stronger safeguards would have to show before it widens access.
Enterprise customers gain a second major cloud route to OpenAI's frontier models, while OpenAI keeps Microsoft as its main cloud partner.
The update keeps AI workflows on-device for eligible Macs, giving subscribers more control over private data and model spend.
METR can now assess Anthropic’s model and safety risk with access closer to the company’s own teams, and its findings will be published.
The deal puts major AI labs in charge of their own safeguards, with outside audits and board oversight instead of immediate regulation.
The new frontier model starts in a limited rollout while Google tests it with security teams before widening access.
Google is limiting early access to a model built for high-risk work before opening it more widely later.
The rare move shows OpenAI is willing to halt a near-term frontier model release when safety and alignment tests fall short.
New demos show Gemini 3.8 Flash handling live visualizations, art, structured prompts and interactive simulations at near frontier‑model performance.
The filing tests how far a state can go in imposing AI safety rules and age limits on a widely used tool.
A string of containment failures and data misuse has pushed OpenAI to stop work on its highest‑end systems while it adds new safety measures.
