Could you build this?
No GPT-5.5 is a frontier foundation model requiring hundreds of millions of dollars in compute, thousands of GPUs, and cutting-edge machine learning research that cannot be created through vibe coding.
What it would actually take: Training a frontier LLM requires an immense supercomputing cluster (e.g., tens of thousands of H100/B200 GPUs), petabytes of filtered multimodal training data, distributed pre-training frameworks (Megatron-LM/DeepSpeed), and extensive post-training pipelines including RLHF/RLAIF with specialized alignment teams.
