## Overview

SmolLM2 is a family of compact language models available in three sizes: 135M, 360M, and 1.7B parameters. These models are designed to solve a wide range of tasks while being lightweight enough for on-device deployment. More details can be found in the [SmolLM2 paper](https://arxiv.org/abs/2502.02737v1).

The **1.7B variant** demonstrates significant improvements over its predecessor, SmolLM1-1.7B, especially in instruction following, knowledge retention, reasoning, and mathematical problem-solving. It was trained on **11 trillion tokens** using a diverse dataset combination, including **FineWeb-Edu, DCLM, The Stack**, and newly curated mathematics and coding datasets that will be released soon.

The **instruct version** of SmolLM2 was developed through **supervised fine-tuning (SFT)** using a mix of public datasets and curated proprietary datasets. It further benefits from **Direct Preference Optimization (DPO)** using **UltraFeedback**. 

Additionally, the instruct model supports tasks such as **text rewriting, summarization, and function calling**, enabled by datasets from **Argilla**, including **Synth-APIGen-v0.1**. The SFT dataset is available at: [SmolTalk SFT Dataset](https://huggingface.co/datasets/HuggingFaceTB/smoltalk).

For further details, visit the [SmolLM2 GitHub repository](https://github.com/huggingface/smollm), where you will find resources for **pre-training, post-training, evaluation, and local inference**.
