Architecture, strengths and use cases

DeepSeek V3.1 is an official self-hostable DeepSeek release in the DeepSeek General track. It uses DeepseekV3ForCausalLM, carries 671B / 37B MoE, supports a verified context window of 163,840 tokens, and exposes only source-certified checkpoints and runtime combinations. Its release, license and deployment facts are tied to the official repository revision rather than inferred from the family name.

DeepSeek V3.1 uses DeepseekV3ForCausalLM with 671B / 37B MoE. The stored architecture profile records 61 layers, hidden width 7168, 128 attention heads and a 163,840 token context ceiling where the official configuration publishes those fields.

Recommended hardware

Use only the listed transformers runtime configuration with the exact checkpoint precision. The recommendation engine checks weight memory, KV cache, runtime overhead, safety headroom, GPU architecture and topology before ranking rentable and reference hardware.

Estimated weight memory643.66 GB
KV cache6.67 GB
Runtime overhead173.7 GB
Total with safety margin1021.81 GB
Technically compatible reference sizing

No current FusionPointAI inventory passes every runtime, architecture, topology and memory gate for this exact checkpoint. Use the estimator for global compatible hardware.

License and self-hosting considerations

The full 671B resident weight set must fit across the selected GPUs. Context and concurrency add KV-cache memory; MoE active parameters do not replace resident-weight memory.

DeepSeek V3.1 is published under MIT License. The release-scoped official license link and verification date are retained with the catalogue record.

Commercial Use Allowed. The official license permits commercial use; its obligations still apply.

Frequently asked questions

How much VRAM does DeepSeek V3.1 require?

The exact estimate depends on checkpoint precision, context and concurrency; the page recommendation uses the certified memory engine and compatible runtime configurations.

Which runtimes support DeepSeek V3.1?

Certified upstream runtime evidence is available for transformers.

Can DeepSeek V3.1 be used commercially?

The stored commercial classification is Commercial Use Allowed. Consult the official MIT License terms for the final obligations.
