DeepSeek: DeepSeek V4.1 Flash 1017 (batch)

DeepSeek V4.1 Flash 1017 (batch) is a DeepSeek model that accepts text and image input and returns text. It offers a context window of 1,048,576 tokens and allows completions of up to 943,718 tokens, so long documents and lengthy outputs fit within a single request. It supports tool calling and reasoning. The listing does not specify structured output support or whether the weights are open, so confirm both before relying on them. The main reason to shortlist it is cost. Input is priced at $0.011 per million tokens and output at $0.2 per million, which suits high-volume workloads where input dominates, such as processing large text or image collections. Quality is unproven, since the model has no independent benchmark coverage yet. Teams should run their own evaluations against current alternatives before committing production traffic, and treat its low price as a reason to test it rather than as evidence of performance.
