Pasting Schematics and DataSheets

I have successfully pasted a number of different schematics and data sheets to ChatGPT 4 and had the circuit correctly analysed. I then chatted about suggested changes and was even more surprised when asked for the data sheet on a component in order to complete the maths and equation.

The only strange thing is some chats can do this if I open an old one and continue, But some new chats on the same day/time cannot. Maybe this is a resource issue?

If anyone knows please add to this topic. But wow thanks OpenAI what an ability.
