Rumor: OpenAI caught off guard by Claude Opus 5.5, GPT-6.1 timeline compressing

An unverified rumor thread claims OpenAI was blindsided—not by the timing but by the performance—of Anthropic's Claude Opus 5.5 launch, with an "all hands on deck" atmosphere around GPT-6.1 Astra and compressed timelines. The poster speculates OpenAI already holds stronger internal models it delayed over recent security issues, and may prioritize GPT-6.1/Astra or a mysterious "Bel" release, with an exciting DevDay ahead. Treat as speculation, not official.
