Research lab
US AI research and product lab founded in 2025 by former OpenAI CTO Mira Murati, building customizable AI models and tools such as the Tinker fine-tuning API.
Bloomberg reports that US frontier labs and the US government are increasingly worried about distillation attacks, and that foreign actors are buying logs of conversations held on legitimate accounts. The detection Anthropic describes happens at request time.
Reality
The San Francisco company now has $50m in total funding and a research preview, Simulations, that runs anomaly detection over replayed user traffic on each pull request. It works only if you already have traffic.
Reality
The $35 million Series A funds a bet that a failure caught in production can be rerun as a pre-merge test, and making that work means standing up stateful fakes of every database, payment system and API the agent touched.
Reality
Anthropic's June decision to keep Fable usage logs for 30 days has turned zero data retention into a procurement gate at Nvidia, Booz Allen and Palantir. The metadata channel stays open under the clause they are demanding.

Open-weight models take about 60 percent of the tokens on US-originating OpenRouter requests, and most of those weights come from Chinese labs, so the marketplace is now selling residency of the inference itself.
Reality
Coordinating a pause on frontier models may read in law as competitors restricting output. Until Congress says otherwise, a lab that wants to slow down has to decide whether it can do so alone.
Reality
The gate on recursive self-improvement is how long one loop takes, and experiments, training runs and new chips all take real time. That makes capability curves fast but bounded, which changes what you sequence first.

A Fortune columnist reads the 2026 AI economy as an unstable system of frontier labs, Chinese open weights and app companies. The checkable part is price, not payoff.
