Provider for the OpenRouter API, using the Omni.Dialects.OpenAICompletions
dialect.
Not loaded by default — must be explicitly enabled. Either add it to your provider list in application config:
config :omni, :providers, [:anthropic, :openai, :google, :openrouter]Or load it at runtime:
Omni.Provider.load([:openrouter])Reads the API key from the OPENROUTER_API_KEY environment variable — no
further configuration is needed if the variable is set.
Configuration
Override the default API key or base URL via application config:
config :omni, Omni.Providers.OpenRouter,
api_key: {:system, "MY_OPENROUTER_KEY"}Any key from the provider's config/0 can be overridden: :api_key,
:base_url. See Omni.Provider for details.
OpenRouter wraps reasoning model output in a reasoning_details format
rather than standard thinking blocks. This is handled automatically —
reasoning data round-trips through Omni.Message.private in multi-turn
conversations without any special handling.
