DeepGEMM is DeepSeek's open-source library of highly optimized FP8 General Matrix Multiplication (GEMM) kernels targeting NVIDIA SM90/SM100 GPUs — the H100, H800, and Blackwell class. The headline feature is a lightweight just-in-time (JIT) compiler that eliminates the need for offline CUDA compilation at install time, dramatically lowering the barrier for teams who want raw GPU throughput without complex build pipelines. The library covers FP8 and FP4 dense GEMMs, BF16 accumulation, grouped GEMMs for Mixture-of-Experts architectures with overlapped NVLink communication, and multi-query attention scoring kernels. On H800 hardware DeepGEMM posts up to 1,550 TFLOPS — competitive with hand-tuned vendor libraries — while remaining fully open source under the MIT license. For LLM inference teams running on H100/H800 clusters, DeepGEMM slots directly into inference stacks like vLLM and SGLang. It's especially notable because it came from DeepSeek's internal training infrastructure, meaning it's been battle-tested at the scale that produced some of 2026's most cost-efficient models. This isn't research code — it's production tooling going public.

QA.tech
AI agent that auto-tests your app on every PR — no code needed

QA.tech is an AI QA agent that learns how your web app works — visually, the way a human tester would — then automatically runs end-to-end tests on every pull request before it merges. You describe test scenarios in plain English; the agent handles the rest, with no selectors, no test code, and no brittle CSS path maintenance. The system builds a knowledge graph of your application's structure and user flows during an initial learning phase, then uses that graph to plan and execute tests intelligently when new PRs come in. When the app changes, the agent adapts its understanding rather than throwing selector-not-found errors like traditional Selenium or Playwright suites. For small teams that can't afford a dedicated QA engineer, or larger teams drowning in flaky test maintenance, QA.tech offers a compelling pitch: describe what matters in plain language and let the agent decide how to verify it. The Product Hunt launch drew strong initial traction from indie developers and early-stage startups looking to add regression coverage without the overhead of a full testing framework.
Reviewer scorecard
“If you're running inference on H100s or H800s, DeepGEMM is an immediate drop-in for the hottest path in your stack. The JIT approach means you're not fighting CUDA version mismatches, and 1,550 TFLOPS is a number that makes you pay attention. Already integrates with vLLM — just use it.”
“The selector-free approach is genuinely appealing to anyone who's wasted hours fixing brittle Playwright tests after a designer changed a class name. If the knowledge graph adapts to UI changes reliably in practice, this could replace an entire category of test maintenance work that nobody enjoys.”
“This is only useful if you're already running H100/H800 clusters — consumer GPU users get nothing here. Documentation is still thin in places, and support for anything below SM90 is explicitly not a priority. Great for DeepSeek's own infra needs; might be too narrow for most teams.”
“AI-driven test agents have been promised before and they consistently struggle with complex stateful flows, modal dialogs, and multi-step auth. The 'adapts to UI changes' claim needs hard evidence — does it catch regressions or just re-learn the broken state? Pricing opacity is also a red flag for budget-sensitive teams.”
“DeepSeek consistently publishes its internal tooling and each release raises the efficiency ceiling for the whole industry. DeepGEMM is another piece of the puzzle that makes frontier inference cheaper — which ultimately benefits everyone downstream from model providers to end users.”
“The end game here is tests written in intent, not implementation. The shift from 'click the button with id=submit' to 'verify the user can complete checkout' is philosophically important — it means tests survive redesigns and become living documentation of what the product is supposed to do.”
“Far outside the creative tooling space but the downstream effect matters: faster, cheaper inference means the models powering creative AI tools get cheaper to run. Not something a designer touches directly, but the efficiency wins flow through to them eventually.”
“As someone who ships design changes and dreads 'breaking the tests,' the idea of tests that understand intent over structure is appealing. If QA.tech can handle responsive layouts and dynamic content reliably, it removes one of the biggest friction points between design iterations and shipping.”
