🍃 MINT-1T:Scaling Open-Source Multimodal Data by 10x: A Multimodal Dataset with One Trillion Tokens
🍃 MINT-1T is an open-source Multimodal INTerleaved dataset with 1 trillion text tokens and 3.4 billion images, a 10x scale-up from existing open-source datasets. Additionally, we include previously untapped sources such as PDFs and ArXiv papers. 🍃 MINT-1T is designed to facilitate research in multimodal pretraining. 🍃 MINT-1T is created by a team from the University of Washington in… See the full description on the dataset page: https://huggingface.co/datasets/mlfoundations/MINT-1T-HTML.pubtabnet-htmlcc-html-tokens-qwen3

648 single-file HTML UI components, generated by
Ornith-1.0-35B on a single
RTX 3060 12GB, paired with the build request that produced each one.
Built to fine-tune a 3B model into writing UI

it stands on its own — distill your own student from it.
The interesting part
The instructions in this dataset are not the prompts that generated the HTML.

CrawlerLM: HTML to JSON Extraction
A synthetic instruction-tuning dataset for training language models to extract structured JSON from HTML.
Dataset Description
This dataset contains HTML paired with structured JSON extraction tasks in chat format. It's designed for fine-tuning small language models to perform structured data extraction from messy, real-world HTML across multiple domains.

AI-Culture Philosophy and Culture Translations CSV + HTML Corpus
The corpus contains an exceptionally diverse range of cultural, philosophical, and literary texts, available in 12 major languages. Among other topics, there is extensive engagement with the ethics and aesthetics of artificial intelligence and its cultural and philosophical implications, as well as connections between AI and philosophy of language and philosophy of mind.

HTML Compression Dataset
This dataset is designed for fine-tuning language models to understand and generate compressed HTML notation.
Dataset Description
The dataset contains pairs of standard HTML and compressed HTML using a custom compression algorithm that:
Abbreviates common HTML tags (div → d, span → s, etc.)
Shortens attribute names (class → c, style → st, etc.)
Compresses CSS patterns (display: flex → d:f, etc.)
Removes unnecessary whitespace and comments… See the full description on the dataset page: https://huggingface.co/datasets/tkattkat101/html-compression.geo_html_200
