Superseded by DeepSeek V4.1 Flash. It no longer holds a current-board position; its all-versions archive rank is #42.
Provider economics and telemetry published by the Hugging Face Router. These are operational signals, not benchmark results.
Structured rows reported in this exact model repository at the pinned revision below. They are the publisher talking about itself: never measured evidence, never a score input on their own. Rows marked as used were laddered against independently measured peers inside the launch-card channel of this model's modeled placement, with the replay-measured optimism haircut applied; the others played no part.
No general-family board lists this model yet. Its point estimate is the precision-weighted mean of every channel that spoke for it; each channel’s share is the weight it carried. Independent measurements replace this placement as boards list the model.
BES normalizes admitted public benchmark evidence for measured Index rows. Its legacy score and observables prior do not define the public language rank.
These adoption and deployment observations remain context only. They do not change this model's ModelCap Index score or rank.
The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.

Market Gravity uses OpenRouter’s full-catalogue popularity order. Sparse Vercel top-ten observations appear only when published and do not affect the score.
This model is visible because it is available in the live catalogue, but it has no trustworthy community result yet. ModelCap does not infer a quality score from price, features, or market activity.

DeepSeek V4 Flash 0731 is a superseded version and is not on the current board as of 22 September 2026. Its archive position, where one exists, is shown on the page; the newer version carries the current rank.
DeepSeek V4 Flash 0731 is listed at $0.04 per 1M input tokens and $0.64 per 1M output tokens as of 22 September 2026; the lowest output price among 28 providers is $0.158 on StreamLake. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $0.40 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.
DeepSeek V4 Flash 0731 has a published context window of 1.3M tokens (1,310,720) and a maximum output of 944K tokens. Individual providers can serve less than the published maximum; the providers table lists each endpoint's own limit.
Open weights (mit). Downloadable weights are published under an OSI or free-culture license in the current repository metadata. This describes weight availability, not whether the full training stack qualifies as Open Source AI. The repository is deepseek-ai/DeepSeek-V4-Flash-0731 on Hugging Face.
28 providers serve DeepSeek V4 Flash 0731 through OpenRouter as of 22 September 2026: OpenInference, Sail Research, Relace, StreamLake, DeepInfra and Inceptron and 22 more. Each provider's price, context limit, quantization and measured uptime are in the providers table above.
DeepSeek V4 Flash 0731 has published results on 1 public board tracked by ModelCap as of 22 September 2026: ARC-AGI-2 61.4% (#53 of 214). Each board page ranks every tracked model on that benchmark; the ModelCap Index combines them with published uncertainty.
