yeah, you’re literally living in the age with best access to information EVER. go download some textbooks and do your own PhD in the evenings after work.
there’s like a hand full of free LLM models, just ask them what you are curious about and tell them to suggest books and build a syllabus for you.
also arXiv Xplorer and ChatPDF are two tools that I find very helpful.
I also use local instances of Deepseek and Llama on LM Studio for when I want to ask spicy stuff that I want to keep private. Plus you can edit the model responses and kinda hack around content filters hehe
