I think the world is sleeping on Korean NPU companies, namely, Rebellions, FuriosaAI, and DeepX. Rebellions and Furiosa are looking to IPO in the latter half of the year, with Furiosa looking to IPO and NASDAQ. NPUs, or inference chips, could drastically reduce the demand for HBMs and GPUs. Korea is investing heavily on three of these NPUs. Recently their version of the Sovereign Wealth Fund was created and the first investments went to these NPU startups. Something to watch.

Summary:

>South Korean AI semiconductor startup Rebellions has successfully run SK Telecom's hyperscale AI model 'A.X K1' on its proprietary NPU server, the 'Rebel Server.' The company processed a model with over 500 billion parameters on a single server without bottlenecks, demonstrating efficiency comparable to global GPU servers, particularly through distributed parallel processing technology for the MoE architecture. The successful demonstration of real-time agent services with zero latency under multi-user concurrent access conditions has significantly boosted the commercialization prospects for domestically produced AI semiconductors. This achievement is being evaluated as a concrete milestone for 'Sovereign AI,' potentially reducing dependency on NVIDIA GPUs.
