Real-Time Data and LLMs: Brainstorming Use-cases

Most popular LLMs like GPT-4 / Llama are powerful but limited by outdated data. I found a GitHub repo that pairs GPT-4 with real-time Amazon discounts. As I'm typing this, I'm exploring if recently released Vertex AI updates by Google provide this. But I'm wondering—what are some important solutions that can arrive with such capabilities? Real-time data could very well transform LLMs into dynamic reasoning engines, opening up new AI possibilities. Mentioned Github repo (not mine): https://github.com/Boburmirzo/chatgpt-api-python-sales
