A.X-K2-NVFP4

skt · A.X-K2-NVFP4

**A.X K2** is a large-scale Mixture-of-Experts (MoE) language model trained from scratch as a high-performance, **agentic** foundation model, and the successor to A.X K1. The model contains **688 billion total parameters**, with **33 billion active parameters**, delivering strong reasoning and instruction-following performance while maintaining practical inference efficiency. Through a **Think-Fusion** training recipe, a single unified model supports both a **thinking** mode for complex problem solving and a **non-thinking** mode for concise, low-latency responses, allowing the user to trade quality for cost on a per-request basis. A.X K2 is developed as part of the Korean government's **Sovereign AI foundation model** project, aiming to build a frontier-scale model with deep understanding of the Korean language and culture.

常见问题

开放权重是否代表可以免费商用?

不一定。应核对具体版本许可证、商用门槛和使用政策。自部署还会产生算力和维护成本。

这些价格是实时结算价格吗?

不是实时结算价格,而是带采集时间的来源报价快照。请到对应渠道核对当前版本、区域、折扣和计费方式。
