DeepSeek Integration

DeepSeek provides an OpenAI-compatible API. You can use it by selecting the OpenAI provider and pointing it to DeepSeek's endpoint.

Configuration

URL Auto-Completion

If you enter just the base URL (https://api.deepseek.com), the extension automatically appends /v1/chat/completions. Both forms work:

• https://api.deepseek.com -> auto-appended to https://api.deepseek.com/v1/chat/completions
• https://api.deepseek.com/v1/chat/completions -> used as-is

Reasoning Models

DeepSeek-R1 and similar reasoning models return two fields:

• reasoning_content / reasoning: The thinking process (not the answer).
• content: The final answer.

The extension prefers content. Only if content is empty does it fall back to reasoning_content.

Anthropic-Compatible Endpoint

DeepSeek also offers an Anthropic-compatible endpoint at https://api.deepseek.com/anthropic. If you prefer the Anthropic provider, use that URL as the base URL.
