Could you build this?
No Step-5 is a foundational frontier large language model requiring massive compute clusters, petabytes of curated data, and specialized ML research teams to pretrain.
What it would actually take: Pretraining a frontier LLM requires an infrastructure cluster of thousands of high-end GPUs (e.g., H100s), massive distributed training frameworks (Megatron-LM, DeepSpeed), proprietary high-quality datasets, and advanced post-training alignment (RLHF/DPO/reasoning distillation).
