DownloadDeepSeek-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.
