A new AI‑driven platform from Tsinghua University, paired with China's exascale supercomputer Tianhe, has slashed drug‑screening time from decades to under a second per target. The system, called Galaxy VS, hosts over 100 billion virtual molecules and millions of protein targets from humans and other species. It is open to researchers worldwide – for free. The team treated protein structures as "search terms" and trained AI to match drug candidates in milliseconds – like a search engine for molecules. Traditional methods would take decades if not centuries to test one target against a 100‑million‑molecule library using a single CPU core, according to a 2020 Harvard Medical School estimate. The computational heavy lifting is done by Tianhe, China's next‑generation exascale supercomputer in Tianjin. In one second, it completes a calculation that would take all 8 billion people on Earth about four years to finish. But raw power wasn't enough. Engineers spent over 700 days translating
