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. They remain quarantined until dataset revision, harness, configuration and identity pass ModelCap’s independent admission review.
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.
Not yet published: the base model it derives from, pinned evaluation dataset versions.

DeepSeek V4.1 Flash is a superseded version and is not on the current board as of 25 October 2026. Its archive position, where one exists, is shown on the page; the newer version carries the current rank.
DeepSeek V4.1 Flash is listed at $0.02 per 1M input tokens and $1.00 per 1M output tokens as of 25 October 2026; the lowest output price among 33 providers is $0.18 on Decart. 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 $0.54 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 V4.1 Flash has a published context window of 1M tokens (1,048,576). The snapshot lists a 943,718 token catalogue-declared route output cap.

33 providers serve DeepSeek V4.1 Flash through OpenRouter as of 25 October 2026: OpenInference, Baidu, Relace, Morph, Decart and Sail Research and 27 more. Each provider's price, context limit, quantization and measured uptime are in the providers table above.
DeepSeek V4.1 Flash has published results on 4 public boards tracked by ModelCap as of 25 October 2026: Arena text 1476 (#34 of 418), Arena coding 1523 (#30 of 413), ARC-AGI-2 72.9% (#53 of 280) and ARC-AGI-3 0.9% (#65 of 110). Each board page ranks every tracked model on that benchmark. The ModelCap Index scores the results its methodology admits, with published uncertainty, and shows reference boards without scoring them.
DeepSeek V4.1 Flash first appeared in the catalogue on 10 Sept 2026. It has since been superseded by DeepSeek V4.1 Flash 1017. Rank and price movements since then are recorded on the site's changes feed.
