DeepSeek-V4.1-Flash-1017 is an open-weight multimodal AI model developed by DeepSeek, designed for advanced reasoning, coding, agentic workflows, and visual understanding. As an updated version of DeepSeek-V4.1-Flash, it delivers improved performance across complex problem-solving, software engineering, autonomous task execution, and image-based reasoning. The model features 763 billion parameters and supports a context window of up to 1 million tokens, enabling it to process extensive documents, codebases, and multi-step conversations. Its enhanced agentic capabilities support tool calling, automated workflows, and complex software development tasks, while improvements in execution speed and output efficiency help reduce computational costs. DeepSeek-V4.1-Flash-1017 also supports configurable reasoning effort, interleaved image content, and integration with inference frameworks such as vLLM and SGLang.

Features

  • Advanced AI Reasoning: Enhanced logical reasoning, complex problem-solving, and configurable thinking modes for challenging analytical tasks.
  • AI Coding and Software Engineering: Improved code generation, debugging, repository-level understanding, and autonomous software development capabilities.
  • Agentic AI and Tool Calling: Supports multi-step agent workflows, external tool integration, task automation, and structured tool interactions.
  • Multimodal Understanding: Processes text and visual inputs for image interpretation, chart analysis, and visual reasoning tasks.
  • 1 Million Token Context Window: Handles long documents, extensive codebases, and complex conversations with support for up to 1 million input tokens.
  • - Open-Weight Deployment and Integration: MIT-licensed model weights with support for self-hosted inference, vLLM, SGLang, and API-compatible deployment workflows.
