Unlimited-OCR is an open-source OCR framework from Baidu that extends Deepseek-OCR to handle single images, multi-page documents, and PDFs. It provides Hugging Face transformer models, PyMuPDF conversion, and an OpenAI-compatible SGLang server for streaming or batch inference. The repo includes setup instructions, example scripts, and configuration for GPU-accelerated parsing.

This article breaks down Andrej Karpathy’s zero-dependency, 243-line GPT implementation in plain Python. It explains how each part—tokenizer, autograd engine, embeddings, attention mechanism, residual connections, and MLP—mirrors a full-scale transformer on a tiny dataset of baby names.

Pingkit is a toolkit designed for training reproducible, capacity-aware models using transformer activations. It offers features for extracting embeddings, training neural architectures, and creating custom probes tailored to specific research needs. The toolkit is integrated with Hugging Face models and provides various utilities for data processing and model training.
