OpenRouter

Runtime provider id: openrouter. Uses the openai-compatible adapter, so reasoning streams for reasoning models.

Provider options

Field	Type	Notes
apiKey	string	Required (or set via environment).
baseURL	string	Optional. Defaults to https://openrouter.ai/api/v1 when omitted.
headers	Record<string, string>	Optional. Extra HTTP headers.
reasoning	object	Optional. See Reasoning.

Model names are usually provider-qualified ids such as anthropic/claude-3.5-sonnet.

Reasoning

reasoning.effort maps to reasoning_effort, which OpenRouter normalizes for reasoning models. Omit to leave reasoning at the default. summary/display are not used by OpenRouter.

Example configs

{
  "name": "OpenRouter",
  "provider": "openrouter",
  "options": {
    "apiKey": "sk-or-..."

  "name": "Claude via OpenRouter",
  "provider": "OpenRouter",
  "options": {
    "model": "anthropic/claude-3.5-sonnet"
  },
  "default": true
}

With reasoning enabled on a reasoning model:

{
  "name": "OpenRouter Reasoning",
  "provider": "openrouter",
  "options": {
    "apiKey": "sk-or-...",
    "reasoning": { "effort": "high" }
  }
}

{
  "name": "DeepSeek R1 via OpenRouter",
  "provider": "OpenRouter Reasoning",
  "options": {
    "model": "deepseek/deepseek-r1"
