LongCat-2.5: Native Multimodality for Agentic Tasks

embedding-shape

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. I'm not saying that the given comparison is inherently bad. I'm saying that they failed to include any useful-to-potential-users reason for why those specific non-current model versions are meaningful.

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.

A cat that is not a Mistral model now that is confusing.

For API, this seems competitive based on the released benchmarks. For running at home, this is pointless when DS4.1 is more or less equivalent but half the total parameters and less than half the active parameters.

The barplots are being miscolored, so only their own model is visible. Its hard to compare them. It highly suggests that the blog post was never looked at by a human.
