Dify is an open-source LLM application development platform. By connecting it to CometAPI, you can use current CometAPI model IDs inside Dify’s workflow, chatbot, and agent builders.

Prerequisites

For model identifiers, refer to the CometAPI Models page. The model ID in Dify must exactly match the identifier used in CometAPI.

​
Troubleshooting

Confirm that the API key is correct and has available balance.
Confirm that the model ID matches exactly what CometAPI expects.
Confirm that the API base URL includes /v1 for the OpenAI-compatible method.
