Mistral-Small-24B-Instruct-2501 GGUF size and VRAM requirements
bartowski/Mistral-Small-24B-Instruct-2501-GGUF is a large instruction-tuned chat model with 23.57 billion parameters, built on the llama architecture. It is released under the apache-2.0 license and has been downloaded 40,083 times.
Under the hood it uses 40 transformer layers, a hidden size of 5,120, 32 attention heads. It uses grouped-query attention (32 query heads sharing 8 key/value heads), which already trims KV-cache memory compared with full multi-head attention.
To run bartowski/Mistral-Small-24B-Instruct-2501-GGUF locally at a 4,096-token context, its quantized versions need between 8.14 GB (IQ2_XS, lowest quality) and 89.25 GB (F32, highest quality) of memory, weights plus KV cache and a system margin included. Context length drives that memory directly: at 4,096 tokens the KV cache for Mistral-Small-24B-Instruct-2501-GGUF is about 0.62 GB, rising to roughly 5.0 GB at its full 32,768-token context. Shorter prompts free up memory for a higher-quality quantization.
For most users the best balance is Q6_K_L, needing about 19.75 GB. That means bartowski/Mistral-Small-24B-Instruct-2501-GGUF fits entirely in the VRAM of a 10 GB GPU or larger, running fully on the GPU.
Available GGUF quantizations for bartowski/Mistral-Small-24B-Instruct-2501-GGUF include IQ2_XS, IQ2_S, IQ2_M, Q2_K, Q2_K_L, IQ3_XS, Q3_K_S, IQ3_M, Q3_K_M, Q3_K_L, IQ4_XS, Q3_K_XL, IQ4_NL, Q4_0, Q4_K_S, Q4_K_M, Q4_K_L, Q4_1, Q5_K_S, Q5_K_M, Q5_K_L, Q6_K, Q6_K_L, Q8_0, F16, F32. The model supports a native context length of up to 32,768 tokens; a longer context grows the KV cache and the memory needed.

Frequently asked questions
What kind of model is bartowski/Mistral-Small-24B-Instruct-2501-GGUF?
bartowski/Mistral-Small-24B-Instruct-2501-GGUF is an instruction-tuned chat model with 23.57 billion parameters, based on the llama architecture. It is released under the apache-2.0 license and distributed as GGUF files for local inference.
How much VRAM do you need to run bartowski/Mistral-Small-24B-Instruct-2501-GGUF?
You need about 9.7 GB of VRAM to run bartowski/Mistral-Small-24B-Instruct-2501-GGUF entirely on the GPU using the Q2_K quantization (at a 4,096-token context). Smaller quantizations lower the requirement at the cost of quality.
Can I run bartowski/Mistral-Small-24B-Instruct-2501-GGUF on an 8 GB GPU?
Partially. bartowski/Mistral-Small-24B-Instruct-2501-GGUF only fits on an 8 GB GPU by offloading part of it to system RAM (with Q6_K_L), which runs but is slower.
Can I run bartowski/Mistral-Small-24B-Instruct-2501-GGUF on a 16 GB GPU?
Yes. With 16 GB of VRAM you can run bartowski/Mistral-Small-24B-Instruct-2501-GGUF fully on the GPU using Q4_1 (about 15.28 GB).
Can I run bartowski/Mistral-Small-24B-Instruct-2501-GGUF on a 24 GB GPU?
Yes. With 24 GB of VRAM you can run bartowski/Mistral-Small-24B-Instruct-2501-GGUF fully on the GPU using Q6_K_L (about 19.75 GB).
What context length does bartowski/Mistral-Small-24B-Instruct-2501-GGUF support?
bartowski/Mistral-Small-24B-Instruct-2501-GGUF supports a native context length of up to 32,768 tokens. A longer context grows the KV cache, so it increases the memory needed to run the model.
What is the best quantization for bartowski/Mistral-Small-24B-Instruct-2501-GGUF?
For bartowski/Mistral-Small-24B-Instruct-2501-GGUF, a strong default is Q4_K_M, which needs about 14.77 GB and keeps most of the quality while roughly halving the memory versus 8-bit. With VRAM to spare, Q5_K_M or Q6_K add a little more quality; if you are tight on memory, a smaller quantization still runs. Pick the highest quantization that fits your VRAM.
