Pattern: Frontier Agentic Coding Models Are Now Trained End-to-End on Domestic Chinese Silicon
LongCat AI·medium signal
LongCat-2.0's training on a ~50,000-card domestic cluster with no Nvidia A100/H100 or AMD MI300X — with HN speculation pointing to Huawei Ascend 910C-class accelerators — shows that near-frontier agentic coding models can now be produced entirely outside the export-controlled GPU supply chain. Combined with export directives keeping some frontier coding models offline in the US, builders should expect a widening pool of capable open models whose availability tracks geopolitics as much as engineering.
