The error you're encountering with the model name "chatgpt-4o-latest" suggests that it might not be recognized by the system. To resolve this, you should verify the available models by calling the `/v1/models` endpoint. This will help ensure that "chatgpt-4o-latest" is indeed a valid model name in your current setup ^{[[1]](https://github.com/lobehub/lobe-chat/blob/main/src/libs/agent-runtime/anthropic/index.ts)}. Regarding the function calling capability, the model must explicitly support this feature. The `isCanUseFC` function checks if a model is enabled for function calls based on its configuration. Ensure that the model's capabilities include `function_calling` ^{[[2]](https://github.com/lobehub/lobe-chat/blob/main/src/libs/agent-runtime/higress/index.ts)}^{[[3]](https://github.com/lobehub/lobe-chat/blob/main/src/services/chat.ts)}^{[[4]](https://github.com/lobehub/lobe-chat/blob/main/src/libs/agent-runtime/mistral/index.ts)}^{[[5]](https://github.com/lobehub/lobe-chat/blob/main/src/libs/agent-runtime/togetherai/index.ts)}. If "chatgpt-4o-latest" is not listed or does not support function calling, it might be due to configuration restrictions or limitations specific to this model version. *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- ^{Help Dosu learn!
