32GB RAM
Calculated for 4-bit (Q4_K_M) @ 8K Context1. Select Quantization Level
Quantization compresses model weights to reduce RAM usage, with minor impacts on output quality.
2. Set Target Context Length
Longer contexts require more active memory for the Key-Value (KV) cache.

Voxtral Small 24B 2507 Memory FAQs
How much RAM does Voxtral Small 24B 2507 require?
To run Voxtral Small 24B 2507 locally, memory size depends on your selected quantization. At 4-bit compression (Q4_K_M), the weights take up ~13.5GB of RAM. When combined with context cache and OS overhead, a standard **32GB system memory kit** is recommended. Unquantized FP16 execution requires a **64GB memory setup**.
What are the hardware requirements to run Voxtral Small 24B 2507 at FP16 precision?
Running Voxtral Small 24B 2507 at unquantized 16-bit precision requires loading ~48GB of model weights directly into VRAM or system memory. A minimum system memory target of **64GB RAM** is required to run the weights stably and avoid out-of-memory crashes.
Is Voxtral Small 24B 2507 dense or Mixture-of-Experts (MoE)?
Voxtral Small 24B 2507 is built on a **Dense** architecture. It features a dense parameter layout containing 24 Billion parameters. All weights are active and computed on every single pass during token generation.
How does context window size affect RAM usage for Voxtral Small 24B 2507?
Context size directly scales the size of the Key-Value (KV) cache. At a standard 8,192 token context, the KV cache for Voxtral Small 24B 2507 uses ~0.06GB. If you scale this to 32K tokens, the KV cache can scale past hundreds of GBs, requiring multi-GPU or workstation-class RAM configurations.
