Beyond DeepSeek V4: A Trillion‑Parameter LLM Trained End‑to‑End on Domestic Chips

The article analyzes how both DeepSeek V4 and Meituan's LongCat‑2.0‑P preview, each with trillion‑scale parameters and 1 M‑token context, were trained and inferred entirely on Chinese‑made accelerators, detailing memory optimizations, deterministic operators, MoE redesigns, and massive multi‑card clusters that prove domestic compute can meet top‑tier AI workloads.
