TaskPriced
TaskPriced compares what AI API calls actually cost per task, including prompt caching and long-context price cliffs, using official OpenAI and Anthropic list prices with source links and verification dates. It includes a model cost calculator (batch and flex discounts, fast and ultrafast multipliers, cache reads and writes, per-request long-context tiers), a usage audit that recalculates spend from your own OpenAI or Anthropic usage export and reconciles it against your cost records to within one cent, and model-switch modelling with a CSV migration plan. Unsupported price combinations are shown as Unsupported instead of guessed. Everything runs locally in your browser, files are never uploaded. Free, no account, and not affiliated with OpenAI or Anthropic.
