Ministral 3 14B Instruct 2512

Frontier 14B multimodal model for high-quality assistants, analytics, and multilingual reasoning.

About model

Ministral 3 14B Instruct is Mistral AI's frontier 14B-class multimodal assistant, combining a 13.5B language core with a 0.4B vision encoder for unified text–image reasoning. With a 256K token context window and strong adherence to system prompts, it is built for long-horizon agents, complex chat experiences, and analytical copilots. Released under an Apache 2.0 license, Ministral 3 14B delivers advanced capabilities while remaining fully open and customizable for deep integration.
Context Window

256K

Long-horizon conversations, documents, and tool-call traces in a single pass.

Frontier-Class Scale

14B

Strong reasoning, coding, and multilingual performance in a compact frontier-tier model.

Multimodal IO

Vision

Joint understanding of documents, screenshots, and natural language queries for rich assistant experiences.

Model key capabilities
  • Multimodal Assistant: Joint text–image reasoning for chat, document analysis, dashboards, and visual Q&A
  • Agentic Tool Use: Native function calling and structured outputs for long-running agents and copilots
  • Multilingual & Code: Broad language coverage and strong code handling for global products and developer tools
  • Long-Context Reasoning: Designed for retrieval-heavy, multi-step workflows that rely on stable 256K context

  • Model card

    Architecture overview:
    • Dense 14B-class language model paired with a lightweight vision encoder, exposed as a single interface for text and images.
    • 256K token context window designed for extended conversations, document analysis, and long-running tool-call traces.
    • Instruction-tuned head focused on stable assistant behavior, schema-following, and controllable output formatting for agents and workflows.

    Training and performance:
    • Trained on diverse multilingual, code, and web-style data to cover a wide range of reasoning and analytic tasks.
    • Instruct variant optimized for dialogue, tool use, and structured outputs rather than raw pretraining perplexity.
    • Positioned to compete with much larger models on many assistant, coding, and reasoning tasks while keeping latency and cost more manageable.

  • Applications & use cases

    Assistants and agents:
    • High-end multilingual assistants for support, operations, and knowledge work that require grounded, explainable responses.
    • Internal copilots that coordinate retrieval, tools, and business logic to automate complex, multi-step workflows.
    • Agentic systems that plan, call tools, and synthesize results into concise recommendations or actions.

    Knowledge, content, and multimodal workflows:
    • Long-document analysis, summarization, and synthesis across technical docs, contracts, product specs, and knowledge bases using the 256K context window.
    • Multimodal understanding of screenshots, diagrams, and document snippets for debugging, troubleshooting, and guided workflows.
    • High-quality content drafting, editing, and transformation across many languages, including structured reports, specifications, and templated outputs.
