- 原文: For my first post, I’m sharing a letter signed on why open models matter. AI will transform every industry, power every company, and be built by every country. Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. The world needs both frontier closed models and frontier open models.

- 原文: Launching Health in ChatGPT to U.S. users. 300 million people use ChatGPT each week for health queries (and my wife and I are among those!). You can now securely connect supported medical records so ChatGPT can understand your personal context and be more helpful to you.

- 原文: "For over two years, the largest open code dataset was The Stack v2… until today. 🥞 The Stack v3 is out: the largest open code dataset ever released: 114 TB, 770 languages, 224M repositories, ~5T tokens of deduplicated and filtered source code. Fully open, no restrictively licensed code included. The upgrade: - v2 (2024): 68 TB raw -> 2 TB / ~550B tokens, 618 languages filtered - v3 (2026): 114 TB raw -> 15.9 TB / ~5T tokens, 713 languages filtered C++ x15, TypeScript x7.5, Rust x7, Python x4.8. Even the COBOL corner of GitHub got a bigger slice. Part of that is two fresh years of open source. Part of it is a bug we found in v2's deduplication - story below. 👀 Things that make v3 different: 1. Contents inline. The #1 complaint about v2 was \"cool dataset, where's the actual code?\" v2 shipped file IDs from the Software Heritage graph, and fetching contents was a DIY treasure hunt. v3 is self-contained: sources embedded directly, one row = one repository. Download finishes -> you start training. 2. Fresh crawl. v2 was a 2023 snapshot of even older crawls. v3 is a direct re-crawl of GitHub at the latest commit, completed by August 2025: 224M repositories, 44B files. Forks were only included if they had 5+ stars. Two ways in: 🥞 stack-v3-train - near-deduplicated, quality-filtered, PII-redacted, contents inline. Point load_dataset at it and go." "🏗 stack-v3-full - the entire 114 TB corpus as an HF Storage Bucket: every duplicate kept with cluster IDs, stubs for excluded files. Roll your own dedup, filters, and mixes." The record isn't really ours to claim - it's millions of everyone's repositories, neatly stacked. Thanks to every developer who keeps their code public, the BigCode community, and friends who built the infrastructure that made this possible!
