gpt-oss
20.5Kopenai/gpt-oss · Python
The gpt-oss series: two open-weight language models from OpenAI — gpt-oss-120b and gpt-oss-20b — built for powerful reasoning, agentic tasks, and versatile developer use cases. The repo itself adds reference implementations, tools, and example clients around the models.

LEANN
13KStarTrail-org/LEANN · Python
LEANN is a vector database that lets you run retrieval-augmented generation (RAG) over millions of personal documents on your own laptop using 97% less storage than traditional vector databases, with no accuracy loss.

dflash
6.2Kz-lab/dflash · Python
DFlash is a lightweight block diffusion model built for speculative decoding, drafting tokens in parallel blocks so a larger target LLM can verify them faster than generating one token at a time.
