# deepseek-recipe

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.
