SmolLM 135M
Tiny 135M fully-open model for on-device AI.
About
SmolLM 135M is the smallest member of Hugging Face's SmolLM family, released July 16, 2024. It was trained on 600 billion tokens of the SmolLM-Corpus, a curated mix of educational and synthetic data including Cosmopedia v2 and FineWeb-Edu, using grouped-query attention and a depth-first architecture.
Released under Apache 2.0 with base and instruct variants, it targets phones, browsers, and embedded devices where a 135M model can run entirely offline. It was a landmark showing that careful data curation can make sub-200M models genuinely useful.
