DeepSeek: DeepSeek V4 Flash Vision Exp

DeepSeek V4 Flash Vision Exp is an experimental model from DeepSeek that accepts both text and image inputs. It offers a context window of 1,048,576 tokens and can return up to 262,144 tokens in a single completion, which suits long documents, large codebases, or extended multi-turn sessions. The model supports tool calling and reasoning; structured output support is not specified, so verify it before relying on schema-constrained responses. At $0.2156 per million input tokens and $0.6468 per million output tokens, it sits at the low end of paid pricing, making it worth shortlisting for high-volume or long-context workloads where cost per call matters. Its benchmark evidence is thin, however: the blended score of 57.7 rests on a single independent benchmark (an AI index score of 57.5), so its standing against alternatives is not well established. Teams should run their own evaluations before committing.
