Evaluation of Brain-to-Text Decoding performance on the test split of the B2T '25 dataset, including Public/Private Word Error Rate (WER) and system resource utilization (RAM, VRAM, RTF).

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Brain-to-Text Decoding |
| Dataset (including any stated split) | B2T '25 (test) |
| Metric | Public WER |
| Unit | PERCENT |
| Direction | Lower is better |
| Results loaded | 3 of 3 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Public WER](<https://www.sota2.com/research/sota/brain-to-text-decoding-on-b2t-25-test.md?metric=Public%20WER>): Lower is better; unit: PERCENT.

- [Private WER](<https://www.sota2.com/research/sota/brain-to-text-decoding-on-b2t-25-test.md?metric=Private%20WER>): Lower is better; unit: PERCENT.

- [RAM Usage](<https://www.sota2.com/research/sota/brain-to-text-decoding-on-b2t-25-test.md?metric=RAM%20Usage>): Lower is better; unit: SIZE.

- [VRAM Usage](<https://www.sota2.com/research/sota/brain-to-text-decoding-on-b2t-25-test.md?metric=VRAM%20Usage>): Lower is better; unit: SIZE.

- [RTF](<https://www.sota2.com/research/sota/brain-to-text-decoding-on-b2t-25-test.md?metric=RTF>): Lower is better; unit: SCALAR.
