@dosubot[bot] commented on GitHub (Jan 9, 2026):

DeepSeek V3.2 tool calling isn't supported in plugin version 0.0.40, especially when using the SiliconFlow plugin—this version only exposes a limited set of image/video tools and doesn't map DeepSeek V3.2 for tool invocation. That's why you see "tool used: Null" in your logs. Official support for DeepSeek V3.2 tool calling was added in newer plugin versions and in other plugins like huaweicloud_maas, along with explicit configuration for function/tool calling features (source, source).

To use tool calling with DeepSeek V3.2, you'll need to upgrade to a newer plugin version where this support is available. Make sure you have the correct API key and endpoint configured, and select the right model in your agent settings (source). If upgrading isn't possible, consider using a different supported model or plugin for tool calling. If you believe your setup should work, sharing error logs or debug output could help pinpoint any other issues.

Image I had the same problem in my previous tests; the tool call in deepseek-ai/DeepSeek-V3.2 was unstable. This is not a plugin issue, but rather a problem with siliconflow. Pro/deepseek-ai/DeepSeek-V3.2 is very stable. The request and message handling are no different for all models in the plugin.

Hi, @Rundong-Li. 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 DeepSeek V3.2 tool calling fails with Dify v1.11.2 and plugin v0.0.40 in a self-hosted Docker setup, showing "tool used: Null" without error logs.
  • It was clarified that plugin v0.0.40, especially with SiliconFlow, does not support DeepSeek V3.2 tool calling.
  • Official support for DeepSeek V3.2 was added in newer plugin versions and other plugins like huaweicloud_maas.
  • The instability is likely due to SiliconFlow's DeepSeek V3.2 rather than the plugin itself.
  • The recommended solution is to upgrade the plugin or use a different supported model/plugin.

Next Steps:

  • Please confirm if this issue is still relevant with the latest version of the dify-official-plugins repository by commenting here.
  • Otherwise, I will automatically close this issue in 5 days.

Thank you for your understanding and contribution!
