@tailored-ai/provider-openrouter

One API key for hundreds of models across vendors. OpenRouter speaks the OpenAI wire format, so this plugin is a thin configuration of core's OpenAIProvider — chat, streaming, tool calling, and model discovery all work out of the box.

Install

bash

tai plugin install @tailored-ai/provider-openrouter

The installer adds the package to your plugins: list automatically.

Configure

yaml

providers:
  openrouter:
    apiKey: "${OPENROUTER_API_KEY}"          # https://openrouter.ai/keys
    defaultModel: "anthropic/claude-haiku-4.5"

agent:
  defaultProvider: openrouter

Per-agent override:

yaml

agents:
  researcher:
    provider: openrouter
    model: "google/gemini-2.5-flash"

Field	Required	Notes
`apiKey`	yes	Use `${OPENROUTER_API_KEY}` to read from the environment.
`defaultModel`	yes	An OpenRouter model id (`vendor/model`).
`baseUrl`	no	Defaults to `https://openrouter.ai/api/v1`. Override for proxies.

Model ids

OpenRouter ids are vendor/model, optionally with a :variant suffix (:free, :nitro). Browse at openrouter.ai/models — or run tai edit, where the model field lists the catalog via listModels.
