| # 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. |
