DeepSeek V4 / V4.1 / MoE

DeepSeek-V4-Pro-0813

Keep the production update distinct from the preview

General availabilitySources checked 2026-09-13

Treat 0813 as its own evaluation target. The August general-availability event is meaningful for service history, but it does not license copying every preview artifact size or benchmark into the later card.

Release context

Why this release matters

DeepSeek’s release log records the Pro update separately. The inspected checkpoint does not establish its total parameter scope, so the reference preserves the exact identity while withholding unsupported weight arithmetic.

This is the dated Pro service update. The exact public checkpoint is separately pinned below.

Deployment starting points

Which hardware, how many, at what precision?

Start with an exact artifact and an engine that supports it. A configuration below is evidence of a documented path; its device count does not promise a particular throughput or concurrency.

No certified hardware configuration in this edition

A capacity decision that depends on an unverified assumption about the later artifact layout.

The pinned model card establishes the architecture. It does not, by itself, prove that a particular GPU count runs this checkpoint at your target context. The capacity screen below helps rule out undersized allocations; a successful load and workload test are still required.

892.73 GB of tensor data in the pinned index

This is the index’s reported tensor payload, in decimal GB. It excludes file headers and runtime memory. Mixed precision, conversion and host/device placement determine how much GPU memory the loaded model needs.

Capacity screen: would the weights fit?

This estimates inference memory for a hypothetical uniform precision. It is useful for rejecting an allocation that is too small. It does not establish a working deployment or estimate training memory.

A uniform-precision GPU count would hide this model’s component layout. Publisher-reported, rounded model count; not an exact tensor census. Multimodal components and packaging can change the artifact size. Use the documented artifact and placement path above; no GPU count is inferred here.

Architecture in practice

What the serving engine has to do

Most experts are stored. Only a few execute.

Compute follows selected experts.

Weight memory follows the full expert store.

A useful comparison

What else belongs on the shortlist?

The preview gives historical context; GLM-5.3 offers a contemporaneous text-agent comparison with a documented hosting path.

Prepare to explain it

The interview lesson

Describe what evidence would establish equivalence: tensor inventory, precision map and pinned configuration, not just a matching model name.

Attention layouts · Quantization · Courses and worked examples

For a deployment evaluation, record exact weights, precision, engine, device count, interconnect, prompt/output lengths and concurrency. Report task success, errors, TTFT, TPOT and useful throughput together.
