Strengths
- Fits a single 24 GB GPU at FP8
- Apache 2.0 with base, instruct and reasoning variants
- Native function calling and image input
Trade-offs to weigh
- Reasoning is a separate checkpoint, not a switch in the instruct model
- Smaller models trail large MoE models on hard agentic tasks

Run it yourself
Released under Apache-2.0. Approximate memory needed just to load the weights:
| Precision | Memory for weights |
|---|---|
| 16-bit (BF16/FP16) | 28 GB |
| 8-bit (FP8/INT8) | 14 GB |
| 4-bit (Q4_K_M, about 4.85 bits) | 8 GB |
Add memory for the KV cache (it grows with context length and concurrent users) and 1-2 GB of runtime overhead. Size it precisely in the VRAM calculator.

Frequently asked questions
How much does Ministral 3 14B cost?
Ministral 3 14B lists at $0.20 per million input tokens and $0.20 per million output tokens (checked October 10, 2026). Mistral API price (ministral-14b-2512); the docs list a single $0.2 per 1M rate (shown twice, unlabeled), read as the same price for input and output. Confirm current rates on the provider's pricing page before you commit.
What is the context window of Ministral 3 14B?
Ministral 3 14B accepts up to 262,144 tokens of context (about 197,000 words, or 390 pages). Long prompts cost more and can be slower, so most apps send only what the task needs.
Is Ministral 3 14B open source?
Ministral 3 14B is an open-weight model released under the Apache-2.0 license. You can download the weights from Hugging Face (mistralai/Ministral-3-14B-Instruct-2512) and run or fine-tune them yourself, within the license terms. Open weights isn't the same as fully open source: training data and code may not be published.
Can I run Ministral 3 14B locally?
Yes, if you have enough memory. The weights alone need about 8 GB at 4-bit quantization and about 28 GB at 16-bit, plus room for the KV cache. Use the VRAM calculator on LLModel.com to check a specific GPU or Mac.
What is Ministral 3 14B best for?
Mistral AI positions Ministral 3 14B for self-hosting, fine-tuning, multilingual, data extraction. It accepts text, images as input, doesn't offer a separate reasoning mode and supports tool calling. Test it on a sample of your own tasks before you choose it for production.
