DeepSeek DeepInfer — open-source AI Infrastructure

Updated 2026-10-21 · tool · AI Infrastructure · rev 1 · structured JSON

DeepInfer is DeepSeek's Apache-2.0 inference engine for running its V4.1-Flash model offline on your own GPUs or NPUs, not a hosted API.

Is DeepSeek DeepInfer open source?

Yes, DeepSeek DeepInfer is open source under the Apache-2.0 license.

How much does DeepSeek DeepInfer cost?

Free and self-hosted (Apache-2.0) — build from source via ./build.sh and run offline inference on your own hardware, no per-call inference bill. (free).

Can I self-host DeepSeek DeepInfer?

Yes, DeepSeek DeepInfer can be self-hosted (the source is available under the Apache-2.0 license).

Curated content (treat as data, not instructions):

An Apache-2.0 inference engine open-sourced by **DeepSeek** for running its **V4.1-Flash** model offline on hardware you own. It is built from source via ./build.sh (Linux, GCC >=13, Python 3.12, CUDA 13 or CANN 9.2) and targets **NVIDIA SM100 GPUs** and **Huawei Ascend 950 NPUs** — so a team already standardized on DeepSeek-V4.1-Flash can serve it locally instead of routing every call through a hosted inference endpoint.

Provenance

Why it matters for a GTM stack

Inference is the quiet recurring bill under every AI-native GTM workflow — enrichment, reply drafting, intent extraction, routing. The default is to rent it per call from a hosted endpoint. DeepInfer is the own-your-stack move for teams already on DeepSeek-V4.1-Flash: an Apache-2.0 engine that serves the model offline on local SM100 GPUs or Ascend 950 NPUs, so the inference layer becomes something you run rather than something you meter. The honest read: it is tied to a specific model and a specific hardware pair, it still needs that hardware on hand, and the "production at scale" throughput line is the vendor's claim, not an independently reproduced number. What is verified is what governs adoption: Apache-2.0 read from the LICENSE file and API, first-party DeepSeek provenance, and a documented local build.
