DeepSeek V4.1 Flash - access through LLMTR
DeepSeek V4.1 Flash offers a 1,000,000-token context window and accepts image input alongside text. It supports tool/function calling. Repeated prompt prefixes are served from a cache and those input tokens bill at one twentieth of the normal input rate. The model reasons by default and those tokens bill as output; even for short answers, set `max_tokens` well above the answer you expect.
