Show HN: 1.32 Petaflops hardware for local prototyping

I’ve been working on Vanta, a scalable AI hardware solution powered by 2–8 NVIDIA RTX 4090s, delivering up to 1.32 petaflops FP32 in a compact form factor.

It’s built for startups, developers and researchers to prototype, fine-tune and run models up to 70B parameters locally. So you can own your computer instead of renting.

- A 2-GPU setup costs $9k and breaks even in 9 months vs. cloud rental at $0.69/hr (ex: RunPod).

- The 8-GPU at $40k saves $12k in year one compared to $48k in cloud costs.

This can handle different AI framework: TensorFlow, PyTorch, ONNX, CUDA-optimized libraries, VLLM, SGLANG, llama.cpp...

I can get it built in a day and shipped out quick. Let me know what you think!
