Notion Adds GPT-5.4 Series and Model Comparison
Notion made several AI model updates this month — three in one go:
GPT-5.4 is here, OpenAI's latest flagship model. It excels at long-chain reasoning — planning, breaking down complex problems, and executing multi-step operations across your workspace.
GPT-5.4 mini and Nano have also been added to the Custom Agent model picker. They're faster and cheaper, ideal for simple tasks like formatting text or quick classification.
