What Exactly Is Mistral Small 3?
Mistral Small 3 is a 24-billion-parameter large language model (LLM) developed by Mistral AI, a French startup gaining rapid traction in the AI community. Released in January 2025, it falls under the permissive Apache 2.0 license, which means:
- You can modify and customize it freely (great for both commercial and personal projects).
- You own the rights to what you build with it, with no hidden fees or complicated usage terms.
- You can deploy it on your own servers, in the cloud, or even on personal hardware without vendor lock-ins.
In other words, Mistral Small 3 gives you enterprise-grade capabilities without the headache of restrictive contracts or massive hardware demands.
Performance at a Glance
Even though Mistral Small 3 “only” has 24B parameters, it rivals larger models like Llama 3.3 (70B) and GPT-4o Mini in multiple benchmarks:
- MMLU (Multi-task Language Understanding): ~81% accuracy, matching or surpassing bigger LLMs.
- HumanEval (Coding): Scores comparable to 30B+ parameter models, excelling at code suggestions and debugging.
- Latency & Speed: Up to 150 tokens/second, with near-instant first-token response times (~0.31 seconds).
- Cost Efficiency: Around $0.15 per million tokens processed—far cheaper than most proprietary APIs.
Simply put, it manages to do more with less, thanks to clever optimizations and advanced training processes.

Under the Hood: How It Achieves High Speed
Mistral Small 3 uses layer pruning, custom attention modules, and smart quantization strategies:
- Pruned Layers: Strips out any transformer layers deemed non-essential, minimizing bottlenecks.
- Dynamic Attention Routing: Allocates more compute to “important” text segments.
- 4-bit/8-bit Quantization: Shrinks model size (down to around 14GB) for faster throughput and lower memory demands.
These optimizations allow Mistral Small 3 to scale from local laptops to enterprise servers without sacrificing performance.
Comparing Mistral Small with Its Rivals
| Model | Parameter Count | Speed (tokens/s) | License | Performance |
|---|---|---|---|---|
| Mistral Small 3 | 24B | ~150 | Apache 2.0 | Rivals 70B models at 3x speed |
| Llama 3.3 | 70B | ~45 | Custom | High accuracy, but bigger |
| GPT-4o Mini | ~20B | ~110 | Proprietary | Good performance, slower |
| Qwen-2.5 (32B) | 32B | ~120 | Apache 2.0 | Strong code skills, slower |
- Key Takeaway: Mistral Small 3 stands out for its speed and cost efficiency, making it a top contender for real-world deployments where responsiveness is key.
