Mistral Small 24B Instruct 2501 (FP32) — 47.5 GBon Scaleway L40S-1-48G

FP32 Scaleway L40S-1-48G

Overview

Mistral Small 24B Instruct 2501 is a 23.57B parameter dense language model by Mistral AI, with code, multilingual, tool-calls capabilities. It supports a context window of up to 32,768 tokens.

Mistral Small 24B Instruct 2501 is a 23.57-billion-parameter dense transformer from Mistral AI, optimized for instruction following, code generation, and multilingual conversation. It occupies a mid-range parameter class that offers strong performance relative to its size, competing with larger 30B models on many benchmarks. The model supports tool calling and 10 languages including English, French, Chinese, and Japanese. With a 32K context window and flash attention, it fits on a single consumer GPU at Q4 quantization for efficient self-hosted inference.

At FP32 quantization (full-precision quality tier), the model weighs 87.82 GB. This exceeds the 48 GB of VRAM on Scaleway L40S-1-48G. Inference is still possible via CPU offload or memory-mapped loading from disk, but expect significantly reduced performance.

The NVIDIA L40S is a datacenter GPU with 48 GB of GDDR6 VRAM and 864 GB/s memory bandwidth. It delivers 362 FP16 TFLOPS with Ada Lovelace architecture. A versatile GPU for AI inference, training, and graphics workloads. Handles quantized models up to 40B parameters comfortably.

Performance Notes

Reduced performance

19 of 40 layers will run on CPU, which may reduce inference speed.

Shorter conversations

Context size has been reduced due to memory constraints. This may affect the model's ability to handle long conversations.

Frequently Asked Questions

How much VRAM does Mistral Small 24B Instruct 2501 (FP32) need?

The FP32 quantization of Mistral Small 24B Instruct 2501 requires 87.82 GB. 21 of 40 layers fit in the 48 GB of VRAM on Scaleway L40S-1-48G; remaining layers are offloaded to CPU.

Can I run Mistral Small 24B Instruct 2501 on Scaleway L40S-1-48G?

Yes, with reduced performance. Scaleway L40S-1-48G can run Mistral Small 24B Instruct 2501 (FP32), but only 21 of 40 layers fit in VRAM. The rest are offloaded to CPU.

What is quantization?

Quantization reduces a model's numerical precision from its original floating-point format to a more compact representation. This shrinks the file size and VRAM footprint, making it possible to run large models on consumer hardware. The trade-off is a small reduction in output quality. FP32 compresses Mistral Small 24B Instruct 2501 from its original size down to 87.82 GB.

What quantization should I choose for Mistral Small 24B Instruct 2501?

FP32 is a full-precision quantization. Higher-quality quants (Q8, Q6) preserve more model accuracy but need more VRAM. Lower quants (Q4, Q3, Q2) reduce VRAM usage at the cost of some quality. Choose based on your available hardware and quality requirements.

What is flash attention and why is it enabled?

Flash attention is a memory-efficient algorithm that speeds up the attention mechanism in transformer models. It reduces VRAM usage during inference by avoiding the materialisation of the full attention matrix. For Mistral Small 24B Instruct 2501 on Scaleway L40S-1-48G, flash attention is enabled to maximise context length and throughput within the available 48 GB of VRAM.

Why are some layers offloaded to CPU?

Scaleway L40S-1-48G has 48 GB of VRAM, but Mistral Small 24B Instruct 2501 (FP32) requires approximately 87.82 GB. Only 21 of 40 layers fit in VRAM; the remaining layers run on CPU, which is slower but still functional.

How do I run Mistral Small 24B Instruct 2501 (FP32) with Ollama?

Run ollama run mistral-small:24b-instruct-2501-fp32 to start Mistral Small 24B Instruct 2501 (FP32). Ollama handles downloading the model weights automatically on first run.
