// category
Language models, fine-tuning and training stacks, quantization, and the runtimes that serve inference.
These are our picks, not a scrape of GitHub trending: every repo here is one we covered in Repository Radar because we thought it worth tracking. Ranked by stars, with live metrics and a get-it block on each.
21 repos in this category. Browse or filter the full archive → · Compare all categories →
21 repos, our 6th-largest category (Agents & Orchestration leads with 92). Combined they're up 64% since we covered them, 9th-fastest-growing of our 9 categories. They hold 784k stars, 5k contributors and 4M weekly downloads between them. Strength runs broad, not top-heavy: the median repo (18k stars) sits close to the 37k average. 7 are breaking out and 19 still actively shipping, and Python leads on language.
