Could you build this?
No This is a flagship frontier multimodal foundation model developed by OpenAI, requiring tens of millions of dollars in compute, custom supercomputers, and deep AI research teams.
What it would actually take: Building a frontier LLM like GPT-6 requires pre-training on clusters of tens of thousands of modern GPUs (e.g., H100s/B200s), petabytes of filtered multimodal training data, and custom distributed training frameworks (Megatron-LM, DeepSpeed). It also necessitates cutting-edge post-training pipelines including RLHF/RLAIF, test-time compute scaling, and custom hardware interconnect infrastructure.
