ClimbMix 40B — Azerbaijani

A large-scale Azerbaijani text dataset created by translating the English 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

from datasets import load_dataset

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

Streaming mode (recommended for large-scale use):

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 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.
