## Selected published results

Figures published by ElevenLabs. Missing cells mean the product page did not publish that measurement for the model.

| Model | Mean first audio (ms) | Full-Duplex-Bench (%) | Speech Agent Arena Elo | Big Bench Audio (%) | Task success (%) |
| --- | --- | --- | --- | --- | --- |
| [Eleven Realtime v1 Mini](/models/eleven-realtime-v1-mini) | 620 | 95.8 | 988 | Not reported | Not reported |
| [Eleven Realtime v1 Max](/models/eleven-realtime-v1-max) | 570 | Not reported | Not reported | 98.8 | 87.1 |

## Interpretation limit

These are selected figures published by ElevenLabs and attributed to an independent evaluator, rather than a complete independently retrieved leaderboard. Big Bench Audio, Full-Duplex-Bench, Speech Agent Arena Elo, task success, and latency have different units and protocols. The page gives no sample counts, uncertainty, evaluation dates, task-success rubric, or benchmark version for Full-Duplex-Bench. Time to first audio is the average measured on Big Bench Audio. Do not merge these figures with similarly named existing benchmark versions or rank Mini against Max on metrics published for only one of them. The third-party figures are not licensed here for Data API redistribution.
