About DeepInfer Field Notes: Independent V4.1-Flash Research

The goal is simple: help a technical reader understand DeepInfer, DeepSeek's V4.1-Flash inference framework — what it open-sourced, what it did not, and how to read the numbers without turning a launch post into a procurement decision.

What this site is

• Independent. No affiliation with DeepSeek, Huawei, NVIDIA, the DeepInfer project, the medical DeepInfer, the smart-contract DeepInfer, or DeepInfra.
• Fan-made. Written by an independent editor who finds the engineering interesting. Enthusiasm is not the same as endorsement.
• Source-based. Every factual claim is tied to a public source: the official repository, the Q&A, the model card, the technical report, or a named media/community source.
• Static. No feed, no comments, no user accounts, no ads, no affiliate links.

DeepInfer and other marks belong to their owners. This site uses the name for identification and commentary only.

What we did — and did not do

We did:

• Read the official README, deployment Q&A, examples, eval docs, model card, and technical report.
• Read the launch-day coverage and the Hacker News thread.
• Cross-check the numbers that appeared in multiple places, and flag the ones that did not.
• Separate what the release contains from what DeepSeek describes as its production design.

We did not:

• Run DeepInfer.
• Have access to SM100 GPUs or Ascend 950 NPUs.
• Perform an independent benchmark.
• Speak to DeepSeek, Huawei, or NVIDIA.

How to read the source labels

When a number is read from a chart rather than a table, we say “approximately” and explain the axis. When a figure appears only in secondary coverage, we do not promote it to the fact table.

Independence and corrections

This site has no advertising, sponsorship, or affiliate links. No company paid for coverage or reviewed a page before publication. DeepInfer is not affiliated with DeepInfra, the commercial inference provider.

Corrections are handled by updating the page and recording the change in the changelog. Because the underlying sources are public, the audit trail is the source register and the linked primary documents. If a claim cannot be traced, it should be removed.

If the official README or Q&A changes, the pages that depend on it need to change too. The snapshot date at the top of each page is there to make that obligation visible.

Privacy

This is a static site. It does not use cookies for tracking, does not require an account, and does not collect personal information. It uses a privacy-friendly Umami analytics script to count page views in aggregate; Umami is cookie-less by design. The site also loads fonts from Google Fonts, which means your browser makes a request to Google's servers; if you prefer to avoid that, block the request or use a font-blocking extension.

No data is sold, shared, or used for advertising.
