Ministral 3B is Mistral's ultra-compact model — 3 billion parameters for on-device and edge deployments where Mistral's instruction-following quality is needed at minimal compute.
Ministral 3B (Mistral) is an AI model released 2025-10 by Mistral AI, a leading organization in large language model research. Ministral 3B by Mistral — compact and efficient model for edge and on-device deployments with solid everyday performance. With 3B and a 128K tokens context window, Ministral 3B (Mistral) is designed to excel across a range of demanding tasks — from software engineering and mathematical problem-solving to multilingual content generation and long-document analysis.
Ministral 3B (Mistral) uses a dense transformer architecture with 3B of parameters, all of which are active for every input token. Dense architectures provide predictable, consistent behavior across diverse task types — there are no "cold" experts to warm up, and quality is uniform across prompts. Mistral AI's training pipeline combined large-scale pretraining on a large-scale multilingual pretraining dataset with supervised fine-tuning and alignment techniques (RLHF or DPO), producing Ministral 3B (Mistral)'s characteristic balance of capability, helpfulness, and safety.
As of 2026-10-16, Ministral 3B (Mistral) by Mistral AI demonstrates measurable performance on standard AI evaluation benchmarks. On MMLU — which tests world knowledge across 57 academic subjects from elementary to professional level — it achieves 67.3%. For software engineering tasks, Ministral 3B (Mistral) scores 58.1% on HumanEval, which tests ability to write correct functions from docstrings. These scores place Ministral 3B (Mistral) — at 3B of parameters — in a competitive position within its model class. Note that benchmark scores reflect controlled evaluation conditions; real-world performance varies by task, prompt design, and domain specificity.
The primary strengths of Ministral 3B (Mistral) are: Compact; Edge deployment; Efficient; Fast. These make it particularly well-suited for Edge devices, Lightweight apps, Quick responses. Users working on complex, multi-step problems benefit most from Ministral 3B (Mistral)'s ability to maintain coherence across long inputs and produce structured, verifiable outputs.
Like all current AI systems, Ministral 3B (Mistral) has limitations: Limited capability vs larger models. For production deployments, validating outputs against authoritative sources — especially for domain-specific or time-sensitive information — remains best practice. Mistral AI continues to improve Ministral 3B (Mistral) through ongoing research.
Ministral 3B (Mistral) is available on LITHOVEX AI with a free account. Unlike direct API access — which requires billing setup, API key management, and per-token charges — LITHOVEX AI provides a seamless browser interface with no setup required, making Ministral 3B (Mistral) accessible to students, researchers, developers, and early-stage teams globally.
