DeepSeek: DeepSeek V4.1 Flash 1017

DeepSeek V4.1 Flash 1017 is a DeepSeek model that accepts text and image inputs and returns text. It offers a context window of 1,048,576 tokens and can generate up to 393,216 tokens in a single completion, which suits long documents, large codebases, or extended multi-turn sessions. It supports tool calling and reasoning. Structured output support is not specified, and its weights are not listed as open. At $0.15 per million input tokens and $0.60 per million output tokens, it sits at the low end of paid pricing. That makes it worth shortlisting for teams running high-volume or long-context workloads where cost per token matters more than proven quality. The caveat is that it has no independent benchmark coverage yet, so its performance relative to similarly priced models is unverified. Run your own evaluations on representative tasks before committing it to production.
