What version of eigent are you using?

latest (as of 2026-04-13)

System information

Reproducible on macOS and Linux (please specify actual environment if different). Happens when setting a Z.ai API key as a BYOK provider in Eigent's model configuration UI.

Problem description

Short Description:
When attempting to configure a custom model for Z.ai (zhipu), validation fails with the error message: 'Unknown model platform: zhipu'.

Expected behavior:
The model platform should be recognized, and API key validation should complete successfully if credentials and endpoint are correct.

Actual behavior:
Regardless of API key or URL, configuration fails and returns the error: 'Unknown model platform: zhipu'.

Repro steps:

1. Go to Settings > Models (BYOK section)
2. Choose Z.ai
3. Enter a valid API key and endpoint
4. Click Save/Verify
5. Observe error message in the UI

Relevant error log:

Unknown model platform: zhipu

Note: Z.ai is mapped to 'zhipu' in the backend, but it appears 'zhipu' is not recognized by the camel-ai model backend. This causes validation to always fail.

log

(See error above. Additional logs can be attached if required.)

Additional context

Suspected root cause

• In backend/app/model/model_platform.py, Z.ai is aliased to 'zhipu'. However, camel-ai ModelFactory (or ModelPlatformType) does not support 'zhipu' as a model platform, leading to the error.
• Possibly missing mapping or incomplete support for Zhipu in camel-ai backend.

Suggested solution

• Either update the aliasing so 'z.ai' maps to an OpenAI-compatible platform (if appropriate),
• OR add explicit support for 'zhipu' in the camel-ai backend if Zhipu models should be supported natively.

Related code reference

• See the PLATFORM_ALIAS_MAPPING in backend/app/model/model_platform.py

Screenshots

Attach screenshots of the settings page and error message if possible.
