DeepSeek V4.1 Flash 1017 - access through LLMTR
DeepSeek V4.1 Flash 1017 is DeepSeek's 17 October 2026 update to V4.1 Flash and stays on that release. It offers a 1,048,576-token context window, accepts image input alongside text and supports tool/function calling. It reasons by default and those tokens bill as output. Images must be sent as base64 data URLs (`data:`). Repeated prompt prefixes can be served from a cache, and those tokens bill at a fifth of the input rate.
