Anthropic released Opus 5.5, OpenAI responded with a GPT-6 update — a week of model drops

The drop race — Opus 5.5 and GPT-6 in 90 minutes, but Meta Muse stole the spotlight
🎭
OpenAI and Anthropic staged a synchronized "model drop week." Anthropic released the Opus 5.5 model. Exactly 90 minutes after the release, OpenAI shipped updates to GPT-6. Ninety minutes — that's the entire interval between two frontier updates.
A separate detail: OpenAI and Anthropic executives had previously talked about "pacing the frontier" — slowing the pace of frontier development.
But the market's attention was captured by Meta with its personal AI agent Muse. According to the publication, Muse is outpacing ChatGPT's early metrics. Plus Muse "is coming to glasses" — a launch on smart glasses has been announced.
Model updates are coming in batches minutes apart, yet the spotlight goes to whoever has a new form factor, not a new version. The TechCrunch podcast episode titled "Meta's Muse just stole the AI spotlight from OpenAI and Anthropic" — materials dated September 27, 2026
