DeepSeek updates V4.1-Flash for faster task execution

DeepSeek has released DeepSeek-V4.1-Flash-1017, a minor update to its V4.1-Flash model that reduces task execution time and output length. The update resolves 77% of tasks on the DeepSWE v1.1 benchmark, up from 74.2% for the September version. DeepSeek also launched a Search API returning up to 50 ranked web results per query and a Fetch API converting web pages to Markdown, both priced at 75 cents per 1,000 requests, with free calls via select tools until November 1. The update follows a five-hour API outage on October 15 for which DeepSeek apologized and issued user credits.
