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.

Groq builds custom LPU (Language Processing Unit) chips that deliver the fastest LLM inference available. Llama and Mistral models run at 500+ tokens/second — 10-20x faster than GPU-based providers.
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 speed is mind-blowing. 500+ tokens/sec makes LLM responses feel instant. For latency-sensitive applications — autocomplete, real-time chat — nothing else comes close.”
“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.”
“Speed is real but model selection is limited to open-source. No GPT or Claude. For apps that need the best model, you still need OpenAI/Anthropic. For speed-first use cases, Groq wins.”
“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.”
“Custom silicon for LLMs is the right long-term bet. GPUs are general-purpose. Groq is purpose-built. As open-source models match GPT quality, Groq becomes the default inference layer.”
“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.”
