sudoraohacker · x · 2026-07-29
The screenshot shows a breakdown of Open Secure AI Alliance signatories, with Anthropic accounting for 533 signatories, or 47.0% of the total. The post argues that this makes the response to the alliance look weak or self-contradictory.
- Anthropic: 533 signatories (47.0%)
- OpenAI (including OpenAI Foundation): 331 (29.2%)
- Google / DeepMind: 192 (16.9%)
- Meta (including Meta AI): 63 (5.6%)
The implication is that the alliance’s support base is heavily concentrated among Anthropic-affiliated people.
