DeepSeek: DeepSeek V4.1 Flash (batch)

DeepSeek V4.1 Flash (batch) is a DeepSeek model that accepts text and image inputs and returns text. It offers a context window of 1,048,576 tokens and allows up to 943,718 completion tokens, so very long documents and lengthy generated 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. At $0.011 per million input tokens and $0.20 per million output tokens, this model belongs on the shortlist for cost-sensitive, high-volume workloads, especially input-heavy jobs where its low input rate matters most. The tradeoff is evidence: it has no independent benchmark coverage yet, so its quality relative to alternatives is unproven. Teams considering it should run their own evaluations on representative tasks before committing production traffic.
