OpenCode ​

OpenCode is an open-source coding agent for the terminal. Running it on LibertAI keeps your code on open-weights models behind a provider entry you control, with nothing proprietary in the setup.

Prerequisites ​

  • OpenCode installed (curl -fsSL https://opencode.ai/install | bash or your package manager)
  • A LibertAI API key — see Get an API key

Easiest path: the LibertAI CLI ​

The LibertAI CLI ships an OpenCode launcher that does the wiring for you:

sh
libertai login       # one-time: browser sign-in or paste an API key
libertai opencode

libertai opencode writes a libertai provider block into ~/.config/opencode/opencode.json (idempotently, leaving your other providers untouched), exports LIBERTAI_API_KEY from the CLI's saved credentials, and launches OpenCode with --model libertai/<your default code model>. It also installs LibertAI's image-generation and web-search agent skills, which OpenCode picks up.

Manual setup ​

OpenCode ignores OPENAI_* environment variables for custom providers; it needs a provider entry in ~/.config/opencode/opencode.json (or a project-local opencode.json):

json
{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "libertai": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "LibertAI",
      "options": {
        "baseURL": "https://api.libertai.io/v1",
        "apiKey": "{env:LIBERTAI_API_KEY}"
      },
      "models": {
        "qwen3.5-122b-a10b": {
          "name": "Qwen 3.5 122B"
        },
        "qwen3.6-35b-a3b": {
          "name": "Qwen 3.6 35B A3B"
        }
      }
    }
  }
}

Then launch with the key in the environment:

sh
LIBERTAI_API_KEY=YOUR_API_KEY opencode --model libertai/qwen3.5-122b-a10b

Verify it works ​

Inside OpenCode, send a trivial prompt:

What model are you, and can you list the files in this directory?

A streamed answer plus a tool call means the provider is live. On an auth error, check the key directly:

sh
curl -i https://api.libertai.io/libertai/auth/check \
  -H "Authorization: Bearer YOUR_API_KEY"

Models ​

qwen3.5-122b-a10b is the recommended default for coding agents (262k context, vision, tools). Add any model id from the model and pricing table to the models map and select it with --model libertai/<id>.
