DeepSeek V4 Flash from DeepSeek: Fast DeepSeek V4 lane for economical reasoning, coding, and long-context work.
The specification score summarizes recorded features and limits. It is not a benchmark result.
Recorded modality support shows what this model can accept and produce. An undocumented modality is shown as unknown rather than assumed to be unsupported.

Fast DeepSeek V4 lane for economical reasoning, coding, and long-context work. The registry places it in the deepseek-flash family with a release date of 2026-04-24. This profile describes its documented interface and how to evaluate it for the intended task.
The recorded inputs are text, with text output. The registry lists a 1,000,000-token context window and up to 384,000 output tokens. It also declares reasoning, function calling and structured output. These are specifications, not a measured quality or speed ranking. A host can impose its own request limits and support a different subset of features.
The registry marks DeepSeek V4 Flash as an open-weight model. Check the linked checkpoint’s licence and runtime requirements before downloading or deploying it. Open weights describe availability, while licence terms determine permitted use. Local inference still requires hardware; a hosted route can charge separately.
No independently checked token rate is added from a hosting alias. Use the route’s current price and billing unit when comparing cost, including output, reasoning, cache behavior and retries where applicable.
Use tasks with checkable intermediate steps and a clear final answer. Keep reasoning settings and tool access consistent across candidates. Count the tokens and retries needed for an accepted result; a context limit or reasoning flag does not predict task accuracy.
This is a registry-sourced profile. A model-specific publisher document has not yet been confirmed; access and specifications should be checked before an integration decision. SyncDev has not independently benchmarked DeepSeek V4 Flash.

The original first-party V4 Flash and V4 Flash Vision Exp models have retired. Their legacy API names are still accepted but are served by V4.1 Flash at its rates. Use deepseek-flash to request the current model explicitly. Downloadable checkpoints and independent hosts have their own deployment lifecycle.

DeepSeek V4 Flash is listed for Text generation. It accepts text and produces text. Use the publisher’s input format and preprocessing for your chosen deployment.
Documented limits: 1M context and 384K maximum output. The listed route charges $0.14 input and $0.28 output per million tokens. Measure a completed task using the prompts, documents and tools your application will use. Include reasoning and retries in the result.
The weights are downloadable under the publisher’s model licence. Check runtime support and size the complete model and working context for your expected concurrency.
These records share a directory category. Check the source card, output type and deployment requirements before treating a model as a replacement.
