K2-V2: A 360-Open, Reasoning-Enhanced LLM [89.7] K2-V2は,スクラッチから構築した360度オープンLLMで,推論適応のための優れた基盤となる。 これはQwen2.5-72Bを上回り、Qwen3-235Bの性能に近づいている。 論文参考訳（メタデータ） (Fri, 05 Dec 2025 22:53:45 GMT)
「We introduce K2, the best fully open-source pretrained large language model (LLM) to date, and ranks competitively against the best open-weight models of its class. As the latest base model in the LLM360 family (Liu et al , 2023; Tao et al , 2024; Liu et al , 2025c; Cheng et al , 2025a), Beyond standard competencies like knowledge and conversation, K2 provides advanced capabilities, including long context consistency, deep mathematical knowledge, and reasoning behaviors. These serve as foundational building blocks that enable sophisticated downstream use cases, such as solving complex math problems and executing agentic workflows.」とオープンかつ強力な性能を主張するLLM
