Could you build this?
No Serving massive LLMs at ultra-high throughput (10k+ tokens/sec) and sub-90ms latency requires custom GPU kernel optimization and specialized model distillation/fine-tuning.
What it would actually take: The core product relies on custom inference runtimes (e.g., FlashAttention, vLLM/TensorRT-LLM with custom Triton or CUDA kernels) deployed on dedicated GPU clusters (H100/B200s). The hard part is fine-tuning and distilling specialized fast models (speculative decoding, context compaction, diff-apply) that maintain accuracy while achieving orders of magnitude faster execution than general LLMs. This requires elite AI infrastructure and CUDA/low-level systems engineers.
