# LongBench Pro 128k+

This dataset is a filtered subset of **LongBench Pro** (`caskcsg/LongBench-Pro`).

## What is included

Only examples whose `token_length` field is one of:

- `128k`
- `256k`

## Columns

This repo keeps only:

- `id`: example identifier (copied from source)
- `text`: the original `context` field (renamed from `context` → `text`)

All other fields from the source dataset are dropped.

## Intended use

Use this dataset when you want to benchmark long-context behavior specifically at **≥128k** length buckets, while keeping the input surface minimal (`id`, `text`).

## Provenance / attribution

Source dataset: `caskcsg/LongBench-Pro`.

This repo contains a derived subset. Please consult the source dataset card for:
- full task definitions
- original annotations/fields
- licensing/usage terms

## Reproducibility

The filtering logic and transformation used to build this dataset are contained in `create_dataset.py` in this repo.
