K2-V2: A 360-Open, Reasoning-Enhanced LLM

Understand

We introduce K2-V2, a 360-open LLM built from scratch as a superior base for reasoning adaptation, in addition to functions such as conversation and knowledge retrieval from general LLMs.

• It stands as the strongest fully open model, rivals open-weight leaders in its size class, outperforms Qwen2.5-72B and approaches the performance of Qwen3-235B.
• We actively infuse domain knowledge, reasoning, long-context, and tool use throughout the training process.
• This explicitly prepares the model for complex reasoning tasks.
