Rates checked 2026-11-10. Tiered, batch, cached-input, peak/off-peak, and regional pricing can differ from the standard planning rate shown here. Confirm the official source before committing budget.
Token APIs use input and output token prices. Per-request APIs use monthly requests. Character-priced TTS uses monthly characters, while token-priced speech models use text and audio token volumes. Vector database estimates use storage and read/write units when the provider publishes them.
The calculator excludes models that miss required context, rate-limit, streaming, JSON, or tool-calling requirements. Custom or purely resource-based pricing is also excluded from numeric ranking.
No. This is a planning dataset with official source links. Model availability, promotions, and account-tier limits can change.
