About o3 pricing

o3 is a model from OpenAI priced per million tokens. Input tokens (your prompt) and output tokens (the response) are billed at separate rates. Cached input pricing applies when the same context is reused, reducing costs on repeated requests. Batch pricing is available for non-real-time workloads at reduced rates.

Pricing data is sourced from official documentation and updated when prices change.
