Small language fashions (SLMs) are gaining recognition as a result of their minimal carbon footprint and low computing necessities. The most recent to affix the bandwagon is SmolLM2 by Hugging Face.
Pushing Small Language Fashions Additional
SmolLM2 is obtainable below an Apache 2.0 license, making it an open-source different. As per the analysis paper, it’s skilled on an in depth dataset of ~11 trillion tokens, combining internet textual content with specialised knowledge like math and code.
The mannequin utilised a multi-stage coaching course of to rebalance from completely different knowledge sources to maximise efficiency.
The researchers additionally expanded on utilizing specialised knowledge, “Moreover, after discovering that current datasets have been too small and/or low-quality, we created the brand new datasets FineMath, Stack-Edu, and SmolTalk (for arithmetic, code, and instruction-following respectively).”
In addition they in contrast the SLM with different current state-of-the-art fashions like Qwen2.5-1.5B and Llama3.2-1B. The analysis was carried out utilizing Lighteval, and it outperformed Qwen and Llama.

The desk above exhibits that the mannequin was examined with varied forms of parameters to check all types of use circumstances.
Summing up the outcomes, the paper states that the AI mannequin beats Qwen2.5-1.5B by round six proportion factors on MMLUPro, proving its capabilities as a helpful generative AI mannequin. Moreover, with the mathematics and coding benchmarks, SmolLM2 reveals aggressive efficiency.
It’s price noting that it couldn’t carry out higher than Qwen2.5-1.5B on a few assessments, together with MATH, but it surely outperforms Llama3.2-1B on the identical.
To elucidate extra concerning the efficiency, the researchers additionally shared about a few assessments not monitored for benchmarks, “SmolLM2 additionally delivers robust efficiency on held-out benchmarks not monitored throughout coaching, akin to MMLU-Professional (Wang et al., 2024c), TriviaQA (Joshi et al., 2017), and Pure Questions (NQ, Kwiatkowski et al., 2019).”
Contemplating the mannequin is open supply, Hugging Face has launched the datasets and the code used for coaching to facilitate future analysis and improvement on SLMs.
It ought to be thrilling to see what the following small language mannequin can do with out organisations worrying about useful resource constraints.
