DeepSeek Anthropic API 兼容性代理 — 让 Claude Code 在 DeepSeek V4 模型上稳定运行

ds-cc-proxy

DeepSeek Anthropic API Proxy · Make Claude Code on DeepSeek V4 stabler and cheaper

Claude Code ←→ localhost:16889 ←→ api.deepseek.com/anthropic

Quick Start · Comparison · 中文

40% cheaper sub-agents. Zero quality loss on primary sessions. Fewer failures than calling DeepSeek directly.

How? Read the thinking field from Claude Code. Route sub-agents (disabled) to Flash with budget_tokens=2048. Passthrough primary sessions (enabled/adaptive) untouched.

Request Type	Primary Session	Sub-agent
CC sends thinking	enabled / adaptive	disabled
CC's intent	Deep reasoning	Quick execution
Proxy routes to	Pro model · original budget	Flash model · budget_tokens=2048
Why	Passthrough — no quality impact	DeepSeek requires enabled; minimal budget satisfies API

Quality is not compromised — it's improved. ds-cc-proxy fixes 12 compatibility bugs in the raw DeepSeek Anthropic API: thinking mode isolation, SSE parsing edge cases, connection pool exhaustion, header leakage, crash-on-invalid-env, and more.

Pick ds-cc-proxy if DeepSeek is your daily driver and you want stability, cost savings, and zero config.

Pick LiteLLM / CCR / OpenRouter if you need multi-provider switching, enterprise RBAC, or don't use DeepSeek thinking modes.

Coexistence with Local Proxies

ds-cc-proxy (127.0.0.1:16889) handles only Claude Code traffic. Clash Verge, V2Ray, and other system-level proxies work at different network layers — run both simultaneously, no configuration needed.

Project Origin

Forked from HosheaLi/P14_dsv4ToCC v1.8.0. Earlier versions were released as dsv4-cc-proxy. v0.1.22 was renamed to ds-cc-proxy. Upgrading:

pip uninstall dsv4-cc-proxy && pip install ds-cc-proxy
