No Training, post-training, and serving a state-of-the-art 1M-context frontier LLM requires massive GPU clusters, distributed systems infrastructure, and elite AI research expertise.
What it would actually take: Requires thousands of high-end GPUs (e.g., H100s/H800s), specialized distributed training frameworks (like Megatron-LM), custom low-level CUDA/Triton kernels for long-context attention, and substantial post-training (RLHF/DPO) pipelines supported by millions of dollars in compute capital.
