Canvas removed in GPT-5.5

Woke up and couldn't use Canvas, thinking I was crazy, so I asked ChatGPT and discovered this 😫. From Chat GPT > Model Release Notes: GPT-5.5 Instant Update (May 28, 2026) We’re updating GPT-5.5 Instant in ChatGPT and the API to improve response style and quality. It’s now easier to read, natural in everyday conversations, and better paced in practical help tasks, with fewer overly long or bullet-heavy responses. With this update, canvas will no longer be available in GPT-5.5 Instant or GPT-5.5 Thinking.
