# SpanishBench

### Paper

SpanishBench is a benchmark for evaluating language models in Spanish tasks. This is, it evaluates the ability of a language model to understand and generate Spanish text. SpanishBench offers a combination of pre-existing, open datasets. All the details of SpanishBench will be published in a paper soon.

The new evaluation datasets included in SpanishBench are:

### Groups and Tasks

#### Groups

- `spanish_bench`: All tasks included in SpanishBench.
- `flores_es`: All FLORES translation tasks from or to Spanish.

#### Tags
- `phrases_es`: Two Phrases_va tasks for language adaptation between Spanish and Valencian.

#### Tasks

The following tasks evaluate tasks on SpanishBench dataset using various scoring methods.
  - `belebele_spa_Latn`
  - `cocoteros_es`
  - `copa_es`
  - `escola`
  - `flores_es`
  - `flores_es-ca`
  - `flores_es-de`
  - `flores_es-en`
  - `flores_es-eu`
  - `flores_es-fr`
  - `flores_es-gl`
  - `flores_es-it`
  - `flores_es-pt`
  - `flores_ca-es`
  - `flores_de-es`
  - `flores_en-es`
  - `flores_eu-es`
  - `flores_fr-es`
  - `flores_gl-es`
  - `flores_it-es`
  - `flores_pt-es`
  - `mgsm_direct_es_spanish_bench` (`spanish_bench` is due to an existing open issue in the original task)
  - `openbookqa_es`
  - `paws_es_spanish_bench` (`spanish_bench` is due to an existing open issue in the original task)
  - `phrases_es`
  - `wnli_es`
  - `xlsum_es`
  - `xnli_es_spanish_bench` (`spanish_bench` is due to an existing open issue in the original task)
  - `xquad_es`
  - `xstorycloze_es`

Some of these tasks are taken from benchmarks already available in LM Evaluation Harness. These are:
- `belebele_spa_Latn`: Belebele Spanish
- `mgsm_direct_es`: MGSM Spanish (fixed an existing open issue in the original task)
- `paws_es`: PAWS-X Spanish (fixed an existing open issue in the original task)
- `xnli_es`: XNLI Spanish (fixed an existing open issue in the original task)
- `xstorycloze_es`: XStoryCloze Spanish

### Checklist

* [x] Is the task an existing benchmark in the literature?
  * [ ] Have you referenced the original paper that introduced the task?
  * [ ] If yes, does the original paper provide a reference implementation?
    * [ ] Yes, original implementation contributed by author of the benchmark

If other tasks on this dataset are already supported:
* [ ] Is the "Main" variant of this task clearly denoted?
* [ ] Have you provided a short sentence in a README on what each new variant adds / evaluates?
* [ ] Have you noted which, if any, published evaluation setups are matched by this variant?

### Changelog

* v1.1 (2025-09-22, PR #3168): add `eqbench_es` task
* v1.2 (2026-01-16, PR #3465): excluded line breaks from stop criteria in `mgsm_direct_es_spanish_bench`
