Hi @202472150920! I'm Dosu and I’m helping the dify-official-plugins team.

The OpenAI Tools plugin in Dify v1.11.2 (plugin v0.1.2) does not use the custom base URL you enter for authentication. The code only passes the API key to the OpenAI client and ignores the base_url parameter, so custom endpoints like ChatAnywhere are not supported for authentication or validation right now. This is a known issue and is why you still see the 401 Unauthorized error even with the correct key and base URL. There are no official fixes or workarounds in the latest release, and no recent pull requests address this bug. For now, using custom OpenAI-compatible endpoints with this plugin is not possible without a code change.
See code reference
