What's New in v2.1.0

Why dsv4-cc-proxy

DeepSeek V4 implements the Anthropic API format, but has 4 critical incompatibilities that break Claude Code. This proxy fixes them transparently.

Non-DeepSeek requests and non-/messages endpoints pass through with zero overhead.

Codex Support

dsv4-cc-proxy also translates between the OpenAI Responses API format and DeepSeek's Chat Completions API, enabling Codex (and other OpenAI Responses API clients) to use DeepSeek V4 models.

Usage
