Served through the OpenRouter gateway and billed per token at the price shown. One key reaches every model here, and a conversation carries over when you switch.
openrouter/anthropic/claude-opus-4Any OpenAI client works: point it at backend.alfnrl.io/v1 and send openrouter/anthropic/claude-opus-4 as the model. Add an X-Thread-Id header to keep a conversation going across models; the quickstart shows it.
