LongCat

Longcat, known in Chinese as 龙猫, is the consumer-facing AI assistant from Meituan, the Chinese local-services company. Rather than a single chatbot, it is the front end of a broader model family developed in-house, spanning language, vIDEo and multimodal systems. The assistant is positioned as an everyday helper that can answer questions, search the web, reason through problems and handle images and voice alongside plAIn text.

What it does

The LongCat APP brings several capabilities into one interface. Users can ask questions in natural language, run searches that pull in current web Information, and switch to a deeper reasoning mode for harder problems. The app also accepts images for understanding and generation, and supports voice and video interACTion. Behind it sits a large Mixture-of-Experts language model with a Long Context window, which Meituan says can process very large inputs in a single pass, making it practical for lengthy documents or extended conversations.

Key capabilities

• Conversational assistance: text Q&Amp;A, brainstorming and drafting across study, work and daily life.
• Web Search and Deep Reasoning: modes that combine retrieval with step-by-step analysis.
• Image handling: generating and interpreting pictures within the Same chat flow.
• Voice and video calls: spoken interaction rather than typing only.
• tool use and coding: the underlying models are tuned for calling tools, multi-step tasks and code generation, and are reported to work with popular coding environments.
• long context: the flagship model is described as supporting roughly one million tokens of input.

Who it is for

LongCat suits General users who want a Chinese-language assistant for research, writing, learning and quick answers. developers may find the companion open models more interesting, since Meituan has released several of them publicly and the family has attracted attention on model routing platforms. Because the interface and documentation are primarily in Chinese, non-Chinese speakers may face a language bARRier.
