DeepSeek open-sourced the inference engine behind its own production AI service.
DeepInfer is the framework DeepSeek uses to serve V4.1 Flash and they're giving away production tricks such as
⥠DSpark speculative decoding
đ§ confidence-scheduled verification
đ SWA bounded replay
âī¸ asynchronous scheduling
đ§Š MoE expert parallelism + load balancing
đ¯ structured JSON / regex / grammar output
đŦ deterministic + batch-invariant inference
Plus DeepSeek's own stack of
FlashMLA + DeepGEMM + DeepEP + DeepSelect + custom TileLang kernels
DeepSeek says that future model inference code + new optimizations will land on this stack too.
This is basically a look inside the code DeepSeek uses to make its enormous models practical to host.
So now other inference harnesses can study the production implementation.
â ī¸ Right now DeepInfer supports only
â no consumer NVIDIA GPUs
â NVIDIA SM100
â Huawei Ascend 950
So this isn't Local AI yet.
