Could you build this?
No Frontier foundation language models require massive supercomputing clusters, tens of millions of dollars in compute, novel ML research, and petabytes of curated data.
What it would actually take: Training a frontier LLM requires thousands of interconnected high-end GPUs (e.g., H100/B200 clusters), specialized distributed training frameworks (Megatron-LM, custom Triton kernels), vast web-scale datasets with sophisticated filtering, and top-tier AI research teams specialized in pretraining, post-training, and RLHF/RLAIF.
