LongCat development and distribution
Meituan develops the LongCat model family. Its November 2 release of LongCat-2.5 combined visual understanding with coding for extended agent tasks. [1][2]
LongCat-2.5 was accessible through chat and an API. TechNode reported that GitHub and Hugging Face releases would follow, so the hosted launch did not establish downloadable weights or a license for running this version independently. [1][2]
