A reliability score,
not a demo score.
Toloka Arena tests agents in controlled, realistic environments with live tools, changing context, and business rules. We repeat equivalent tasks to capture whether a system is consistently useful, not just occasionally correct.
- 01
- Fresh environmentsTasks and data are held out from model training and public benchmark contamination.
- 02
- End-to-end successScoring considers correct tool use, policy adherence, and a completed task state.
- 03
- Repeated trialsEvery score aggregates independent task attempts to surface reliability and variance.
