i don't think you can assume that - "real time" in this context could just mean they feed every article into their training system as soon as it's published.
Fine-tuning, which is cheaper and faster, has been proven to not be a good solution to "teach" models new facts.
I think what's most likely here is that Gemini will have access to a form of RAG based on a database of AP articles that gets updated in real-time as new articles are published.
