China's LongCat-2.5 AI model trained on domestic hardware, bypassing Nvidia

By PulseAugur Editorial · [1 sources] ·

Meituan has released LongCat-2.5, a 1.6-trillion-parameter AI model designed for agents and long-context tasks, under an MIT license. Notably, the model was trained entirely on Chinese hardware, specifically Huawei Ascend accelerators, bypassing the need for Nvidia GPUs. While Meituan claims competitive performance against previous-generation frontier models like Claude Opus-5 and GPT 5.6 "Sol" on certain benchmarks, independent leaderboards suggest it aligns more with prior-generation capabilities. AI

IMPACT Demonstrates China's capability to train large AI models without Western hardware, potentially impacting global AI development and supply chains.
