    DeepSeek ships a minor V4.1-Flash update: faster reasoning, coding and agent tasks with shorter outputs

    DeepSeek released DeepSeek-V4.1-Flash-1017, a minor update to DeepSeek-V4.1-Flash that brings substantial gains on reasoning, coding, agentic tasks and visual benchmarks. The update also cuts task execution time and output length, letting users finish tasks faster and at lower cost and pushing the performance-cost Pareto frontier across several agent harnesses. The release ships no Jinja chat template, offering instead a Python reference implementation and the Rust library deepseek-recipe for prompt encoding.

  2. DeepSeek ships V4.1-Flash-1017 for building whole projects from scratch, and opens its search and fetch APIs to everyone

    DeepSeek released DeepSeek-V4.1-Flash-1017, which it says delivers stronger benchmark performance, faster task completion and shorter outputs than the previous version, a Pareto improvement in performance and cost, now live on its website, app and API. The model uses reinforcement learning with self-feedback to improve end-to-end project development, with demos spanning 3D modeling, a web racing game and a Godot-engine recreation. The Search and Fetch APIs also opened to everyone at $0.75 per 1,000 calls per endpoint.
