Install OpenCode using the [official instructions](https://opencode.ai/docs/). Run `opencode`, enter `/connect`, choose Other and use `infistar` as the provider ID. Enter your Infistar key.

Create `opencode.json` in your project:

```json
{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "infistar": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "Infistar",
      "options": { "baseURL": "https://infistar.ai/v1" },
      "models": { "MODEL_ID": { "name": "MODEL_ID" } }
    }
  }
}
```

Replace MODEL_ID with a model available to the key. Restart OpenCode, enter `/models` and select it. The provider ID must match in `/connect` and the configuration.


## Check the connection

Use an exact model ID available to your key, and begin with a short text request. For coding agents, first ask for a reply without reading or changing files or running commands. A successful text reply does not verify every tool or multimodal feature.

For 401, check the key and its status. For 404, check the address and protocol. For model errors, recheck the model ID and selected group. See [HTTP troubleshooting](/en/troubleshooting/http-status-troubleshooting).
