There’s no built-in Dify feature to collapse or hide the <think></think> tag pair in workflow output, but there are a few approaches depending on your version and needs:

• If you’re on Dify v0.15.3 or later, the platform wraps the thinking process in a collapsible HTML <details> tag, visually separating it from the final answer. This makes the reasoning section collapsible in the UI automatically source.
• In older versions (like 1.7.2), the output node simply renders whatever is passed—including <think> tags—so you’ll need to filter or collapse these tags manually. The best way is to update your frontend code (for example, in the Answer or AgentContent React component) to detect and either hide or wrap <think> blocks in a collapsible element before rendering source.
• If you see [ENDTHINKFLAG] instead of </think>, that’s due to tokenizer filtering. You can fix this by updating your LLM’s tokenizer_config.json to stop filtering out <think> tags and restarting the model source.
• There’s currently no backend config to suppress or collapse <think> tags; if you want to fully remove them, you’ll need to strip them out in your backend or frontend code before displaying the result source.

Let me know your Dify version if you want more specific code guidance!
