Model provider
Use DeepSeek models in Douchat
DeepSeek's API is compatible with the OpenAI Chat Completions format, so you can add it as a custom provider and run any agent on DeepSeek models.

Set it up like any OpenAI-compatible provider
Enter the DeepSeek API address, your key and the model IDs. Mark reasoning models so Douchat gives them a larger output budget.
Your account, your bill
Usage is billed by DeepSeek to your account. Your key is encrypted on your computer and never synced.
