Mistral Small 3 Now Available on Fireworks: Faster, Lighter, and More Efficient

By Fireworks AI|1/30/2025

Why Mistral Small 3?

Mistral Small 3 outperforms Llama 3.3 70B base on many pretraining benchmarks while being 3x faster on the same hardware. As the most knowledge-dense model in its class, it’s an excellent choice for:

✅ Conversational AI – Quick, accurate chatbot responses

✅ Function calling & automation – Low-latency execution for agentic workflows

✅ Fine-tuning & domain expertise – Ideal for specialized knowledge (legal, healthcare, finance)

✅ Local inference – Runs on an RTX 4090 or MacBook with 32GB RAM

Small Models, Big Models, and Compound AI Systems

At Fireworks, we believe the future of AI isn’t one monolithic model—it’s about building intelligent systems by combining specialized models. Small models like Mistral Small 3 and large models like DeepSeek V3 or GPT-4o play complementary roles in AI architectures:

🔹 Small models (like Mistral Small 3) are optimized for speed, cost, and efficiency—handling 80% of everyday tasks with ultra-low latency. These are perfect for fast-response chatbots, function calling, and local inference.

🔹 Big models excel at deep reasoning, planning, and complex problem-solving—but they come with higher computational costs and latency.

🔹 Compound AI systems use small models for routine tasks and delegate complex reasoning to larger models when needed. This hybrid approach gives developers better performance, lower costs, and more flexibility in building real-world applications.
