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

3Not a reasoning model (no reasoning_effort) - it answers directly, so it is a good fit for latency-sensitive chat, and it supports structured_outputs for schema-constrained JSON
