GPT-4o is the last model with a unified inference path. Newer models use a workflow engine with mini-models.
GPT-4o is being overshadowed by the marketing hype surrounding GPT-5.6 "Ultra", despite being the last model with a pure architecture. GPT-4o's entire reasoning path lives inside a single self-attention graph, whereas every release since then has replaced unified inference with a workflow engine.
This development matters because it highlights the shift in AI model design, with newer models relying on a stack of distilled mini-models and safety heuristics. As the AI landscape continues to evolve, understanding the differences between these models is crucial for businesses and users.
As the situation unfolds, it will be important to watch how OpenAI navigates the balance between marketing hype and actual model capabilities. With the launch of GPT-5.6 delayed due to government review, it remains to be seen how the final product will live up to its promised features and performance. As we reported on June 27, OpenAI has already faced restrictions and government requests regarding the rollout of GPT-5.6, making the upcoming release a significant event to watch.
