Available packages

| Quantization | Size | Approx. RAM | Recommended for |

| --- | ---: | ---: | --- |

| Q4_K_M | 13.3 GiB | 21.23 GB | Most users |

| Q5_K_M | 15.6 GiB | 24.51 GB | Higher quality |

| Q8_0 | 23.3 GiB | 35.7 GB | Plenty of memory |

Memory values are estimates, not guarantees. Runtime configuration and context length change actual use.

Multimodal projector

| File | Precision | Size |

| --- | --- | ---: |

| Devstral-Small-2-24B-Instruct-2512-mmproj-F16.gguf | F16 | 837.4 MiB |

The projector is required for image input and must be used with one of the language-model GGUF files above.

Backpack recommendation

Recommended: Q4_K_M. It usually offers a practical quality, size, and speed balance for local inference.

Run with llama.cpp

Using the llama.cpp revision recorded below:

llama-mtmd-cli --model Devstral-Small-2-24B-Instruct-2512-Q4_K_M.gguf --mmproj Devstral-Small-2-24B-Instruct-2512-mmproj-F16.gguf --image image.jpg --prompt "Describe this image."

Run with Backpack

These artifacts and backpack-model.yaml are prepared for the Backpack AI workspace.

Provenance

The source model was resolved to immutable revision 55c5b41e98c2dbd21b0c8afffc540dcfc9eb5128. It was converted with llama.cpp's convert_hf_to_gguf.py, including its multimodal projector, and quantized with llama-quantize; the exact tested revision is recorded above and in backpack-model.yaml.

License and attribution

Upstream declares apache-2.0. Review the upstream model card and comply with all applicable terms.

Backpack does not claim ownership of the original model. These artifacts are packaged and quantized distributions of the upstream model.

Disclaimer

Quantization can alter output quality. Memory estimates vary with runtime configuration, context length, and hardware.
