TL;DR

The issue is likely due to Hermes not using the configured Opencode Zen model, instead falling back to the default anthropic/claude-opus-4.6 model, and a workaround may involve verifying the API key and model configuration.

Guidance

• Verify that the Opencode Zen API key is valid and correctly configured in the config.yml file.
• Check that the base_url field in the config.yml file is correctly set for the Opencode Zen provider.
• Ensure that the account associated with the Opencode Zen API key has access to the qwen3-coder model.
• Review the Hermes documentation to confirm that the config.yml file is being loaded correctly and that the model configuration is valid.

Example

No code snippet is provided as the issue seems to be related to configuration rather than code.

Notes

The issue may be related to the way Hermes handles model configuration and API key validation. Further investigation into the Hermes documentation and configuration options may be necessary to resolve the issue.

Recommendation

Apply workaround: Verify the API key and model configuration to ensure that Hermes is using the correct model. This is recommended as the issue seems to be related to configuration rather than a code bug, and verifying the configuration may resolve the issue without requiring a code change.
