AI Rate CardDeepSeek: DeepSeek V4.1 Flash 1017 · fastrouter
DeepSeek-V4.1-Flash-1017 is the October 17, 2026 update to DeepSeek-V4.1-Flash, a multimodal Mixture-of-Experts model that natively accepts text and images, with a 1M-token context window and MIT license. It improves reasoning, coding, agentic tasks, and visual benchmarks over V4.1 Flash while reducing task execution time and output length, so tasks finish faster and cheaper. DeepInfra serves it in fp8 with JSON output, function calling, and zero data retention, plus Priority and Flex service tiers. DeepSeek reports DeepSWE v1.1 at 77.0 (up from 74.2) and Terminal-Bench 4.0 at 42.3 (up from 31.2) versus V4.1 Flash.
