#Canvas Issue.

If you have the Canvas feature turned on but ChatGPT is not opening Canvas when you expect it to (e.g., after clicking "Canvas" and sending a message), this may not be intentional behavior. According to OpenAI's documentation, Canvas should open automatically in scenarios where ChatGPT detects that an interface for writing or code would be helpful—such as when generating content greater than 10 lines, or when you explicitly request it (e.g., by saying “use canvas…” or “open a canvas”) or use the canvas shortcut in the composer. You can also trigger Canvas by typing “/canvas” or using the Toolbox dropdown. If these methods are not opening Canvas, it could indicate a bug or a temporary issue with the feature.
Additionally, note that you can no longer open a canvas by selecting GPT-4o with canvas from the model selector at the top of the page; the workflow has changed, and Canvas is now triggered contextually or via the new shortcuts and commands. If you are following these updated methods and Canvas still does not open, it is likely not intentional and may require troubleshooting or reporting to support. You may also want to ensure you are using a supported platform (Web, Windows, or MacOS) and that your app is up to date, as Canvas is not yet available on mobile platforms. If the issue persists, contacting OpenAI support would be advisable What is the canvas feature in ChatGPT and how do I use it?.
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

Let me check the knowledge base for you again. One moment! :books:
If you have the Canvas feature enabled but ChatGPT is not opening Canvas when you expect it to—such as after clicking "Canvas" and sending a message—this is not the intended behavior according to OpenAI’s documentation. Canvas should open automatically in certain scenarios (like when generating longer content or when you explicitly request it with commands such as “open a canvas” or “use canvas…”), or you can trigger it using the /canvas command or the Toolbox dropdown. The option to select GPT-4o with canvas from the model selector has been removed, so Canvas is now triggered contextually or via these shortcuts.
