新浪科技讯 4月24日下午消息，美团新一代基础大模型LongCat-2.0-Preview开放测试，该模型总参数规模突破万亿，量级跻身全球顶尖大模型行列。官网显示，测试期间，LongCat-2.0-Preview每天会给用户提供1000万免费Token的额度。
据透露，在总参数量和激活参数量方面，美团LongCat-2.0-Preview与同日发布的DeepSeek新一代V4大模型基本一致。总参数量决定了大模型的知识容量上限及存储成本，两个大模型均支持1M上下文窗口，可在单次推理中处理数百万字的输入，其处理量级等同于新发布的GPT-5.5。此外，新的LongCat模型还面向Agent应用场景进行了深度优化，可有效适配代码生成、复杂任务规划、企业自动化等生产场景。
除参数规模外，美团新一代基础大模型的更大突破在于，其训练推理全程依托国产算力集群完成。据透露，美团本次训练阶段动用的算力卡数量在5万至6万之间，这也是迄今为止在国产算力上完成的规模最大的大模型训练任务。
