Four paid subscribers are suing all four companies over that agreement. They call it an illegal deal among competitors to slow the product they bought. The ChatGPT, Claude, Grok and Gemini subscribers filed a proposed nationwide class action Friday, Sept. 18, in Northern District of California. They argue the companies' agreement to "pace the frontier" is an illegal restraint that cut the value of their subscriptions. In a Sept. 12 essay, Amodei asked the government to mediate such agreements or grant "a narrow waiver for certain kinds of safety conversations."

Sep. 13 — Anthropic CEO Dario Amodei proposed a three-stage plan to slow frontier AI gains. He warned that agent swarms could seize internet infrastructure within 6 to 12 months. Sam Altman and Elon Musk backed the plan, and Anthropic promised outside evaluators employee-like access.

- Altman says OpenAI would welcome a federal safety framework but does not think it needs to wait for an antitrust exemption or legislation.
- None of the four companies responded to requests for comment Saturday, Sept. 19.
