    Estimate covers public standard text input and output rates only. If your provider bills reasoning or thinking tokens as output, include them in your output-token estimate; this calculator does not infer them. It excludes cached-token pricing, batch discounts, external tools and search, embeddings, vector stores, hosting and infrastructure, negotiated discounts, free-tier credits, and image, audio, video, or voice usage.

    How OpenAI API text pricing works

    OpenAI bills input tokens and output tokens at separate rates. Enter average tokens for one request and your total daily request count. Token Breaker multiplies those values by the public rate listed for the selected model.

    GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna have a higher rate when a prompt exceeds 272,000 input tokens. That higher input and output rate applies to the full request, so the estimate changes tiers when your average prompt crosses that threshold.

    Prices and lifecycle information in this review were checked on October 17, 2026. The table links to OpenAI’s pricing and lifecycle pages. Future prices are displayed with their effective date, and the calculator uses them once that date arrives.
