Could you build this?
No Training a 770B MoE frontier LLM with 1M context requires massive high-performance GPU clusters, tens of millions of dollars in compute, and advanced distributed ML systems expertise.
What it would actually take: Requires thousands of interconnected high-end GPUs (e.g., H100/H800 clusters), 3D parallelism frameworks (Megatron-LM, DeepSpeed), proprietary MoE routing algorithms, petabytes of high-quality tokenized text and code, and specialized RLHF post-training research teams.
