# Providers (OpenCode V2)

OpenCode includes a provider and model catalog from models.dev. For most providers, connect an account first, then select a model.

## Setup
Run /connect, choose a provider, and enter its credentials. Then run /models to select one of its models.

## Custom
Add a provider when its API is not already in the catalog. This OpenAI-compatible example defines the credential, runtime package, endpoint, and first model together.

Example:
{
  "$schema": "https://opencode.ai/config.json",
  "providers": {
    "acme": {
      "name": "Acme",
      "env": ["ACME_API_KEY"],
      "package": "@opencode/ai/providers/openai-compatible",
      "settings": { "baseURL": "https://llm.acme.example/v1" },
      "models": { "qwen3-coder": { "name": "Qwen 3 Coder" } }
    }
  }
}

The providers object is keyed by the provider ID used in model references, such as acme/qwen3-coder.

Fields: name, env, package, canonical, compatibility, settings, headers, body, models.

## Endpoint
Override settings.baseURL to send a catalog provider through a proxy or compatible endpoint.

## Packages
Native package options include openai, openai-compatible, anthropic, google, azure, amazon-bedrock, openrouter, xai, etc. You can also use npm packages or file:// URLs.

## Errors
- No model is available for session: no enabled model selectable.
- Model unavailable: provider/model: provider inactive, model ID absent/disabled, or discovery no longer returns it.
- Cannot initialize provider/model: a placeholder remains in baseURL. Set that variable on the OpenCode server or replace the template with a complete endpoint.
