Tips & Best Practices

1Works with the OpenAI SDK - set base_url to https://ai.api.core.today/llm/openrouter/v1
2Charged at OpenRouter's usage.cost x 1,858 credits/USD - the listed rates are estimates and may lag OpenRouter price changes
3OpenRouter's shared pool for this model may intermittently return 429 - retry with exponential backoff rather than treating it as a hard failure
