This is, Ministral 3 14B Base 2512 is a vision-language model: a text backbone paired with a vision encoder, supporting image understanding alongside text. This is the base pre-trained checkpoint — not instruction- or chat-tuned. For chat/instruction-following use cases, use the Instruct variant instead; this base checkpoint is intended for custom post-training/fine-tuning.

Community note. Structural check confirms the vision tower and multimodal projector were carried over intact (not dropped, which is a real failure mode for text-only conversion tools on vision-language models). Functional check (running generation) could not be completed on the maintainer's hardware -- this bf16 (unquantized) checkpoint needs ~26.6GB of GPU memory to generate, which exceeds the practical ceiling on a 32GB Apple Silicon machine (reproducibly hits a Metal out-of-memory error, not a one-off fluke). The weights themselves are an unmodified dtype/format conversion (no quantization math applied), so there's no reason to expect a correctness issue -- but generation hasn't actually been run end-to-end. If you have a Mac with more unified memory (64GB+), please open a discussion with your results.

Heads up

• Base model, not instruct-tuned — expect raw completion behavior, not chat-following. Don't expect it to follow instructions well.
• Vision retained at full precision — only the language backbone is quantized; the vision tower and multimodal projector are untouched bf16, per mlx-vlm's standard policy of not quantizing multimodal modules.
• Output size on disk: 27.92GB

Provenance

• Source: mistralai/Ministral-3-14B-Base-2512 (BF16)
• Language model layers: 16 (bf16, unquantized)-bit affine quantization, group_size=n/a
• Vision tower + multimodal projector: kept at full precision (not quantized)
• Blended average: 16 (bf16, unquantized) bits per weight across all parameters
