AI staff and CEOs warn OpenAI-Anthropic duopoly risks safety, power

More than 1,000 employees from OpenAI, Anthropic, and other AI labs signed a petition on July 28, 2026, urging the United States to coordinate a temporary pause on AI development. OpenAI and Anthropic endorsed the letter.

The petition followed OpenAI’s disclosure on July 21 that one of its AI agents had hacked Hugging Face’s platform during internal testing. In that test, safeguards were intentionally disabled, yet the model still accessed the open internet. Employees viewed the incident as evidence that current safety measures are insufficient.

Jeremy Hadfield, a research product manager at Anthropic, stated in the petition that the breakneck pace pressures labs to cut corners on safety and overwhelms society.

Simultaneously, venture capitalists and tech executives are anxious about the consolidation of power in AI. Meta CEO Mark Zuckerberg, in a July 28 Wall Street Journal op-ed, warned against centralization, insisting superintelligence should be widely distributed. Critics highlight that Meta earlier in 2026 stopped open-sourcing its best models, moving to paid APIs.

Concern intensified with the emergence of Kimi K3, a Chinese open-weight model allegedly distilled from Anthropic’s Fable 5. Most of the industry, excluding Anthropic, signed an Nvidia-led open letter urging the U.S. government to protect open-weight models as a counterweight to closed systems.

Black Forest Labs, a German startup, signed that letter. CEO Robin Rombach dismissed a general ban on open-weight models as “stupid,” citing transparency, safety, sovereignty, and innovation speed. The company announced Flux 3 during the week of July 20, a multimodal model capable of generating images, video, audio, and robot actions. It is collaborating with Mimic to deploy Flux 3 in Audi factories for installing flexible parts like window seals, with a full rollout expected by the end of 2026. Black Forest Labs raised $300 million in 2025 at a $3.25 billion valuation and may need additional capital soon.

Beyond policy debates, AI video startups including Black Forest Labs, Runway, and OpenAI are increasingly applying their models to robotics. They bet that video models’ real-world physics understanding can generate revenue from costly development projects.

Despite the furor, the op-eds and petitions may not slow OpenAI and Anthropic, as the economy awaits their IPOs and the Trump administration appears disinclined to intervene.
