| # MTEB Portuguese |
|
|
| A public benchmark for evaluating text embedding models on **Brazilian Portuguese**, built as a thin extension on top of the [`mteb`](https://github.com/embeddings-benchmark/mteb) library. |
|
|
| ## What you'll find here |
|
|
| - 🏆 **[Leaderboard](https://huggingface.co/spaces/mteb-pt/leaderboard)** — interactive ranking, 54 models × 16 tasks, Pareto chart |
| - 📊 **[`mteb-pt-results`](https://huggingface.co/datasets/mteb-pt/mteb-pt-results)** — all per-task JSONs + per-query parquets, ~1100 files |
| - 💻 **[GitHub repo](https://github.com/tardellirs/mteb-pt)** — task definitions, evaluation scripts, paper sources, issue templates |
|
|
| ## Submit a model |
|
|
| We accept submissions via either channel — pick whichever fits: |
|
|
| - 💬 [HF Discussion on the results dataset](https://huggingface.co/datasets/mteb-pt/mteb-pt-results/discussions/new) |
| - 🐛 [GitHub Issue with the model template](https://github.com/tardellirs/mteb-pt/issues/new?template=submit-model.yml) |
|
|
| Required for a submission: |
| 1. `model_id` (HF repo path or vendor product name) |
| 2. Per-task result JSONs for the 16 headline tasks |
| 3. Reproducible evaluation command |
|
|
| We re-run a sample of each submission to verify before merging. |
|
|
| ## Propose a new task |
|
|
| Open a [GitHub Issue with the task template](https://github.com/tardellirs/mteb-pt/issues/new?template=propose-task.yml) describing the dataset, license, size, and discrimination evidence. A task is accepted if it's native PT-BR (not machine-translated), has clear licensing, and discriminates between models. |
