这种类型的公告帖，应该附加benchmark成绩/竞品模型对比，不然都没人知道模型的定位，更加不会有人直接买API的啊😅 要是再好点，可以上OpenRouter之类搞一个短期免费试用的，更有说服力。 longcat你们都做到2.5了，发公告应该能熟练点了吧

is it actually 1M context or does it become unusable at 500k tokens?

a TRILLION parameter model by a FOOD DELIVERY startup btw. maybe a dumb question, but how do these seemingly random Chinese companies have the resources/talent to make their own models?

Meituan is much more than a food delivery company. It’s one of China’s largest local-services platforms, with deep reach into restaurants, hotels, travel, mobility, merchants, and everyday consumer services. So it’s not that surprising to see them build a large model. China has a deep AI talent pool, and domestic compute is also becoming much more capable. LongCat-2.0 was already trained and served on a 50,000-chip Chinese accelerator cluster, so the infrastructure side is clearly catching up too.
