One API key, every agent. g0i is OpenAI-compatible and Anthropic-compatible — point your tool at our base URL, paste the key, and use Claude Opus 5.5 and Sonnet 5, GPT-6, Gemini 3.1, Kimi K3, and other currently published models. Check the guide for your tool and the capabilities of your selected model.
Paste one command, paste your API key, pick Claude Code, Codex, OpenCode or Kimi Code — the script installs it if it's missing and writes the config for you. No files to edit; your old config is backed up.
Open a terminal and paste:
curl -fsSL https://g0i.ai/install.sh.txt | bash
Re-run it any time to switch key or model. Prefer doing it by hand? The manual steps are below.
Anthropic's native CLI agent that lives in your terminal — runs Claude Opus, Sonnet, Fable and Haiku against your local codebase.
Open-source autonomous coding agent for VSCode. Reads files, writes diffs, runs commands — all gated behind your approval.
A fork of VSCode built around AI pair-programming. Custom models work via Cursor's OpenAI-compatible custom endpoint.
OpenAI's flagship terminal coding agent. Uses the new Responses API with WebSocket streaming for low-latency tool calls.
Bun-based open-source coding agent (sst.dev/opencode). Uses the AI SDK with first-class OpenAI Responses support.
Moonshot AI's official CLI (kimi-code-cli) for agentic coding with the Kimi K-series. Point it at g0i and run Kimi K3 plus the K2.7 variants through one OpenAI-compatible endpoint.
If it speaks the OpenAI or Anthropic API, it works with g0i. Drop a message — we'll add a setup guide for it.
