Does Coze work with OpenRouter or third-party models? Yes, but only if you treat it as an "interface compatibility issue" rather than a "brand choice issue". Someone has already given a very direct judgment in the open issue: the model API provided by OpenRouter should be OpenAI-Compatible, so it can be connected according to the OpenAI protocol first.
The official Coze Studio open-source repository is still https://github.com/coze-dev/coze-studio. The model configuration in the repository and the community response emphasize the same thing: as long as the provider's interface shape matches, Coze can take it; If the interface is not compatible, even if the model name is familiar, it may not work.
Let's look at the two most critical words first
The first one is 'OpenAI-Compatible' and the second is 'base_url'. The reason why many third-party models are not connected is not because the model itself is not good, but because you wrote 'base_url' incorrectly or chose the wrong protocol type. For example, some platforms need to take the compatibility mode path, and some people in the community change 'base_url' to '.../compatible-mode/v1' before it runs.
Why does the model show but the call fails?
Because "being able to be configured" and "being able to be properly requested" are not the same thing. Just because Coze reads your model information first doesn't mean it really knows which address to send what requests to which address. As long as there is a mistake in the path, return format, and authentication method, 400, 405, JSON parsing may fail, or it may look completely unresponsive.
More stable connection
- If the provider clearly states that it is OpenAI-Compatible, it will be connected using the OpenAI protocol first.
- If the provider has a compatible mode path, try to fill in the compatible address given by the official.
- First, use the minimum request to verify the interface, and then stack the capabilities of the knowledge base and workflow.
This kind of question is not "does Coze support a certain platform", but "does this platform expose interfaces in a way that Coze can understand". The interface is aligned, and many third-party models can be connected smoothly.
One sentence conclusion
Coze can connect with OpenRouter and many third-party models, but only if they actually provide OpenAI-Compatible interfaces and have the 'base_url', protocol, and return format aligned. Connect the interface first, then select the model, and avoid detours.
