OpenCode supports custom providers through its config file, using the OpenAI-compatible surface.

```json
{
  "provider": {
    "claudeapikey": {
      "npm": "@ai-sdk/openai-compatible",
      "options": {
        "baseURL": "https://aiprimetech.io/v1",
        "apiKey": "sk-your-key"
      },
      "models": {
        "claude-sonnet-4-6": {"name": "Claude Sonnet 4.6"},
        "claude-opus-4-8": {"name": "Claude Opus 4.8"}
      }
    }
  }
}
```

Config lives at `~/.config/opencode/opencode.json` or `opencode.json` in the project root. Restart OpenCode and select the provider.

> OpenCode is under fast development and its config schema moves. If the block above is rejected, check the provider section of OpenCode's own docs — the values you need are always base URL `https://aiprimetech.io/v1`, your key, and exact model ids.
