# ClimbMix 40B — Azerbaijani

A large-scale Azerbaijani text dataset created by translating the English [karpathy/climbmix-400b-shuffle](https://huggingface.co/datasets/karpathy/climbmix-400b-shuffle) dataset into Azerbaijani using Google Translate.

## Dataset Summary

This dataset contains approximately **40 billion tokens** of Azerbaijani text, making it one of the largest publicly available Azerbaijani language corpora. It is intended for pretraining and fine-tuning large language models (LLMs) for the Azerbaijani language.

## Dataset Structure

Each row contains a single field:

| Column | Type   | Description           |
|--------|--------|-----------------------|
| `text` | string | Azerbaijani text body |

## Usage

```python
from datasets import load_dataset

ds = load_dataset("LocalDoc/climbmix-40b-az")
print(ds)
```

Streaming mode (recommended for large-scale use):

```python
from datasets import load_dataset

ds = load_dataset("LocalDoc/climbmix-40b-az", streaming=True)

for sample in ds["train"]:
    print(sample["text"])
    break
```

## Source Data

The original [climbmix-400b-shuffle](https://huggingface.co/datasets/karpathy/climbmix-400b-shuffle) dataset was created by Andrej Karpathy and contains a diverse mixture of English web text covering a wide range of topics including science, technology, history, literature, Q&A, and more.

## Translation

All text was translated from English to Azerbaijani using **Google Translate** via automated batch processing. While machine translation introduces certain limitations (see below), the scale of this dataset makes it a valuable resource for Azerbaijani NLP given the scarcity of large native corpora.

## Limitations

- **Machine translation quality**: Text was translated automatically and may contain unnatural phrasing, calques from English, or translation errors — especially for idiomatic expressions and domain-specific terminology.
- **Cultural context**: Some content may not reflect native Azerbaijani cultural context, as it originates from English-language sources.
- **Agglutinative morphology**: Azerbaijani is an agglutinative language with complex suffix structures; machine translation does not always handle these correctly.
- **Recommended use**: Suitable for LLM pretraining and vocabulary learning. Not recommended as the sole resource for high-precision fine-tuning tasks.
