Summary
A new Japanese neocloud, ai&, has launched on Tenstorrent hardware in one of the largest such deployments outside the US. Its CEO asserts that NVIDIA's CUDA ecosystem no longer constitutes a defensible moat, signaling growing confidence in alternative AI accelerator stacks for commercial deployment.
Why it matters
- ai& is one of the largest Tenstorrent deployments outside the US, providing rare real-world scale evidence for an alternative AI accelerator stack
- CEO's 'CUDA moat is gone' claim signals commercial operators now believe non-NVIDIA hardware is viable for serious workloads, not just research
- A Japanese neocloud adopting Tenstorrent suggests geographic diversification of AI infrastructure away from NVIDIA-dominated US hyperscalers
