How many GPUs to run Mistral Small 3 24B
Fewest GPUs that fit the weights plus one 8K-token request. Data-center GPUs use vLLM (90% of memory usable), the others llama.cpp. Several GPUs split the model with tensor or pipeline parallelism.

Cheapest way to run Mistral Small 3 24B today
For each GPU: the fewest cards that fit Mistral Small 3 24B with one 8K-token request, the most faithful weight format at that count, and the cheapest on-demand price (2026-10-30).
On-demand prices from AWS, Google Cloud, Azure, RunPod, Vast.ai, Oracle Cloud, OVHcloud, Scaleway, Verda, Akash and UpCloud, checked every hour. Serving many users needs more KV cache, so more memory: size it in the calculator. Some links are affiliate links: StudioTV may earn a commission, at no extra cost to you.
vLLM and SGLang apply these defaults unless a request sets its own. With llama.cpp, pass them yourself: --temp 0.15
KV cache: how memory grows with context
Architecture: 40 layers · GQA, 8 KV heads × 128. Every layer keeps keys and values for every token (grouped-query attention), so the cache grows linearly with context.

Mistral Small 3 24B VRAM FAQ
How much VRAM does Mistral Small 3 24B need?
In BF16 the weights alone take 43.9 GiB (47 GB). In FP8 that is 23.2 GiB, and about 13.4 GiB with 4-bit quantization (Q4_K_M). Each request then adds KV cache: 1.25 GiB at 8K tokens and 5.00 GiB at 32K (BF16 cache).
Can Mistral Small 3 24B run on a single RTX 4090 (24 GB)?
Yes. In Q4_K_M it fits on one RTX 4090 with an 8K-token context (14.6 GiB including the cache, with llama.cpp).
Can Mistral Small 3 24B run on an RTX 5090 (32 GB)?
Yes. In Q8_0 (24.5 GiB with an 8K-token context) it fits on one RTX 5090, with llama.cpp.
Can Mistral Small 3 24B run on a Mac?
Yes. In 4-bit (Q4_K_M with llama.cpp) it needs a Mac with 24 GB of unified memory or more, of which macOS gives the GPU about 16 GB, for one request with an 8K-token context. In 8-bit (Q8_0) it needs 48 GB or more.
Can Mistral Small 3 24B run on a DGX Spark or a Ryzen AI Max+ 395 (128 GB)?
Yes. In BF16 (45.2 GiB with an 8K-token context) it fits on a DGX Spark (128 GB) and on a Ryzen AI Max+ 395 with 128 GB, whose GPU gets up to 96 GB, with llama.cpp and one request.
What is the cheapest way to run Mistral Small 3 24B?
On 2026-10-30, the cheapest on-demand setup is 1 × NVIDIA L4 (24 GB) with 4-bit weights on Vast.ai, at $0.104 per hour (about $75.92 per month). Next: 1 × GeForce RTX 3090 (24 GB) with Q4_K_M weights on Vast.ai, at $0.121 per hour. Sized for one 8K-token request; prices are checked every hour.
How many H100 GPUs does Mistral Small 3 24B need?
With one request and an 8K-token context: 1 in BF16, 1 in FP8 and 1 in 4-bit (vLLM, 90% of memory usable). Serving many users at once needs more memory for their KV caches: the calculator sizes that for you.
What temperature should I use with Mistral Small 3 24B?
The official defaults are temperature 0.15.
What is Mistral Small 3 24B's knowledge cutoff?
October 2023, according to OpenRouter: it knows little about later events.
