Seemingly has links to GitHub and HuggingFace, but no actually explanation about what we're supposed to be able to find there "soon". Is this supposed to be downloadable weights? Open weights? Who knows?

One link to "https://longcat.ai/chat/" is provided, which eventually redirects you to https://passport.mykeeta.com/pc/login, did the UI get hacked or something? I went to mykeeta.com which doesn't respond, passport.mykeeta.com serves OpenResty's default page, not sure what's going on but looks strange.

Asking "Hello?" in the chat you get "你好!我是 LongCat,美团研发的大模型助手。有什么可以帮你的吗?" back, which is an explanation what LongCat is in Mandarin. If you then write "What?", it does web-searches trying to explain what "What?" means, in Mandarin.

I'm not really sure this is ready to even be played around with yet. Some more basic prompts seems to tell me that despite the benchmark results, it's fairly dumb, so gut tells me this is benchmaxxed then pushed out as quickly as possible.

> "the charts below compare it with GPT-5.5, GPT-5.6-Sol, Claude-Opus-4.8, and Claude-Opus-5"

There should be a rule against releasing seemingly-obsolete comparisons without explaining why you're doing it. If you don't give a cost reason, it makes you look like you're trying to hide something.

AshamedBadger56•38m ago
I would suspect the point of the older comparisons is to be able to show that local models have caught up to where frontier models were a few months ago.
Imustaskforhelp•35m ago
I know this is besides the point but I genuinely remember a time not very long ago that people used to say that they would kill for an claude opus 5 model at home or an open weights model and that opus 4.8/5 are the first models which finally get what they are suggesting.

Seems like our expectations and the floor has been rising at such an exponential rate.

Has someone created a benchmark for our expectations to see how much they've grown for new model releases? I'd be curious to see some of the data :-D

I don't think you're going to be running this 1.6 trillion parameter model at home.

Imustaskforhelp•28m ago
I know that but given that it's most likely seems to be an open-weights model or that you can still run theoretically at home without being at the whims of Anthropic/OpenAI is still quite extraordinary.

Same price as DS4.1F: https://longcat.ai/platform/docs/pricing/longcat-2.5

On benchmarks they seem comparable. The wild cards are the cache hit rate and speed.
