README

Cost per successful task

**A benchmark that measures what it actually costs to get a task *done*, not what a token costs.**

Most model comparisons quote price per million tokens. Production systems care about something different: *what did it cost to successfully complete the task?* Retries, failed tool calls, malformed outputs, and runs that grind to the token limit all cost real money that a token-price benchmark hides.

cost per successful task = total $ spent on a model across ALL attempts
                           ---------------------------------------------
                                   number of successful runs

This repo is a small, instrumented agent that runs real [Terminal-Bench](https://www.tbench.ai) tasks in Docker, grades each run with the task's own tests, and reports cost-per-successful-task per model. Every run is traced to [Arize AX](https://arize.com).

The finding

40 tasks × 10 models × 6 trials (2,400 runs), across four providers. Prices verified 2026-07-07, 2026-07-14, and 2026-07-16. Every one of the 400 (task, model) cells has exactly 6 trials.

Takeaways the metric makes visible:

  • *The cheapest model per success has the worst pass rate.
