DeepGEMM is DeepSeek's open-source CUDA kernel library for high-performance matrix multiplications used in large-scale LLM training and inference. The April 2026 update is the most significant since launch, adding Mega MoE (fused Mixture-of-Experts layers with overlapped NVLink communication), FP8×FP4 mixed-precision GEMM, an FP4 Indexer for efficient token routing, and faster JIT compilation across the board. The headline number is 1550 TFLOPS on H800 GPUs — a substantial jump that makes this directly relevant for anyone running MoE-based models at scale. The Mega MoE addition specifically targets the bottleneck in distributed inference where GPU-to-GPU communication eats into compute efficiency, a problem that grows worse as model and cluster sizes increase. The library continues to be fully open-source and JIT-compiled, meaning it ships without prebuilt binaries and adapts to the target hardware at runtime. For ML infrastructure teams building on DeepSeek's architecture or running large MoE models in production, this update is a material performance unlock.

Replicate lets you run open-source models (Llama, Stable Diffusion, Whisper) via API without managing GPUs. Push your own models with Cog or use community models. Pay only for compute time.
Reviewer scorecard
“1550 TFLOPS on H800 with FP8xFP4 is not a marginal gain — this is the kind of kernel work that makes large MoE deployments economically viable. If you're running DeepSeek-style architectures, benchmark this immediately.”
“The easiest way to run open-source models without managing infrastructure. One API call to run Llama, Whisper, or any custom model. Cold starts can be slow though.”
“JIT compilation means you're compiling on first run, which adds friction in reproducible production pipelines. This is infrastructure for specialists — most teams should wait for these gains to flow through higher-level frameworks like vLLM before touching it directly.”
“Cold start latency is the main issue — first request can take 10-30 seconds. Fine for batch jobs, problematic for real-time. But the convenience factor is huge.”
“The FP4 push is significant: FP4 is the next compression frontier for inference at scale. DeepSeek open-sourcing their kernel work here accelerates the entire ecosystem's ability to run frontier-class models cheaply.”
“Replicate is making open-source AI as easy to use as closed APIs. That is the right mission at the right time.”
“Pure infrastructure — unless you're personally operating GPU clusters, this update is invisible to you. The benefits will trickle down through cheaper API pricing in a few months.”
