deepclaude

Skill by ara.so — Daily 2026 Skills collection.

deepclaude routes Claude Code's API calls to DeepSeek V4 Pro, OpenRouter, Fireworks AI, or any Anthropic-compatible backend — keeping the full Claude Code UX (file editing, bash, subagents, git) while cutting costs by up to 17x.

How it works

Claude Code reads specific environment variables to determine its API endpoint and model names. deepclaude sets these per-session (not permanently), launches Claude Code, then restores originals on exit.

Your terminal
  └── Claude Code CLI (tool loop, file editing, bash, git — unchanged)
        └── API calls → DeepSeek V4 Pro ($0.87/M) instead of Anthropic ($15/M)
