We've just released BIOMEDICA, an open-source resource making all scientific articles from PubMed Central Open Access conveniently accessible for model training through Hugging Face, with accompanying tags and metadata. Includes 24M image-text pairs from 6M articles, annotations,
Biomedical datasets are often confined to specific domains, missing valuable insights from adjacent fields. To bridge this gap, we present BIOMEDICA: an open-source framework to extract and serialize PMC-OA. 📄Paper: https://t.co/zkb2m5yeal 🌐Website: https://t.co/atIKEfOpkv

As a RL research myself, I once doubted Reinforcement Learning (RL) because massive self-supervised LLMs were dominating. But now I see how RL can bring us closer to super-intelligent (ASI) systems—far beyond board games. Here’s what changed my mind: (1/5)
