Mistral-Small-2501

All notebooks are beginner friendly! Add your dataset, click "Run All", and you'll get a 2x faster finetuned model which can be exported to GGUF, vLLM or uploaded to Hugging Face.

• * Kaggle has 2x T4s, but we use 1. Due to overhead, 1x T4 is 5x faster.

Model Card for Mistral-Small-24B-Instruct-2501

Mistral Small 3 ( 2501 ) sets a new benchmark in the "small" Large Language Models category below 70B, boasting 24B parameters and achieving state-of-the-art capabilities comparable to larger models! This model is an instruction-fine-tuned version of the base model: Mistral-Small-24B-Base-2501.

Mistral Small can be deployed locally and is exceptionally "knowledge-dense", fitting in a single RTX 4090 or a 32GB RAM MacBook once quantized. Perfect for:

• Fast response conversational agents.
• Low latency function calling.
• Subject matter experts via fine-tuning.
• Local inference for hobbyists and organizations handling sensitive data.

For enterprises that need specialized capabilities (increased context, particular modalities, domain specific knowledge, etc.), we will be releasing commercial models beyond what Mistral AI contributes to the community.

This release demonstrates our commitment to open source, serving as a strong base model.

Benchmark results

Human evaluated benchmarks

Note:

• We conducted side by side evaluations with an external third-party vendor, on a set of over 1k proprietary coding and generalist prompts.
• Evaluators were tasked with selecting their preferred model response from anonymized generations produced by Mistral Small 3 vs another model.
• We are aware that in some cases the benchmarks on human judgement starkly differ from publicly available benchmarks, but have taken extra caution in verifying a fair evaluation. We are confident that the above benchmarks are valid.

Publicly accesible benchmarks

Reasoning & Knowledge

Math & Coding

• Performance accuracy on all benchmarks were obtained through the same internal evaluation pipeline - as such, numbers may vary slightly from previously reported performance (Qwen2.5-32B-Instruct, Llama-3.3-70B-Instruct, Gemma-2-27B-IT).
• Judge based evals such as Wildbench, Arena hard and MTBench were based on gpt-4o-2024-05-13.

Usage

The model can be used with the following frameworks;

• vllm: See here
• transformers: See here

vLLM

We recommend using this model with the vLLM library to implement production-ready inference pipelines. Note 1: We recommond using a relatively low temperature, such as temperature=0.15. Note 2: Make sure to add a system prompt to the model to best tailer it for your needs. If you want to use the model as a general assistant, we recommend the following system prompt:

system_prompt = """You are Mistral Small 3, a Large Language Model (LLM) created by Mistral AI, a French startup headquartered in Paris.
