The right harness for every LLM
Claude in Claude Code, GPT in Codex, Gemini in Antigravity or Gemini CLI, Qwen in Qwen Code, everything else through OpenCode or Goose, over ACP. Local models are routed by family.
Run Claude, GPT, Gemini, Qwen and local models in parallel, each in the harness made for it, each on its own git worktree. Switch models without losing the conversation, bring a friend into the session and keep going from your phone.
