Steps to reproduce

Qwen3 provides a method to modify whether the thinking mode is enabled through prompts, where adding /think will activate it and adding /no_think will deactivate it. This functionality aligns with expectations for Qwen3's open-source models. Image

However, this functionality does not work as expected in Qwen3's commercial models, which include qwen-plus-2025-04-28/latest and qwen-turbo-2025-04-28/latest. The thinking mode in these commercial versions cannot be activated through prompt commands.

✔️ Expected Behavior

Support enabling/disabling the thinking mode in Qwen3's commercial models through prompt commands.

Actual Behavior

No response

Qwen3 business edition thinking mode default is off, and you need to on it manually to use /think and /no_think. Note: Qwen3 open-source edition thinking mode default is on.

Hi, @Liu-Tianmeng. I'm Dosu, and I'm helping the dify-official-plugins team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You reported that the /think and /no_think commands work in Qwen3 open-source models but not in commercial qwen-plus and qwen-turbo models.
  • The maintainer explained that thinking mode is off by default in the Qwen3 business edition and must be enabled manually.
  • This difference in default settings accounts for the commands not working out of the box in commercial versions.
  • The issue was resolved with this clarification.

Next Steps:

  • Please confirm if this explanation still applies to the latest version of the dify-official-plugins repository.
  • If it does, you can keep the discussion open by commenting on this issue; otherwise, I will automatically close it in 5 days.

Thank you for your understanding and contribution!
