Introducing canvas, a new way to write and code with ChatGPT.

OpenAI launched the canvas beta on October 3, 2024 for ChatGPT Plus and Team users, adding a GPT-4o-based workspace for writing and coding beyond chat. The post says canvas can auto-trigger or open via “use canvas,” supports targeted edits, version restore, and shortcuts like code review and bug fixing. The key signal is model training: across 20+ internal evals, trigger accuracy reached 83% for writing and 94% for coding, targeted edits beat baseline by 18%, and comment accuracy and quality improved by 30% and 16%.
