MODEL_NOT_FOUND

还没翻译译自英文（docs.langchain.com）本页 7 段都还没译

Note

Currently only used in langchainjs (JavaScript/TypeScript).

The model name you have specified is not acknowledged by your provider.

Troubleshooting

To resolve this error:

  1. Verify the model identifier: Double check the model string you are passing in. Ensure the spelling and format are correct
  2. Check proxy/wrapper configurations: If you are using a proxy or other alternative host with a model wrapper, confirm that the permitted model names are not restricted or altered

The error typically stems from either a typo in the model name string itself or restrictions imposed by a proxy service or model wrapper between your code and the provider's API.
