@martyk Those are the top AI frontier models. Google Gemini is the other. The numbers are just their latest versions. I have used them all and find I consistently obtain better results from Claude. Plus, I like Claude's company Anthropic more than ChatGPT's company OpenAi. Anthropic still has some morals. For deeper research I suggest switching Claude's model mode from Sonnet 4.6 over to Opus 4.5 and select the "research" option. I hope that helps. Other readers may have different opinions than me.

These tools help me with research. The trick is know how to describe your questions for the AI prompt. There are many videos on YouTube that could help you get started as a beginner if you give it a try. Just keep in mind that AI gets its training from the internet and does its search on the internet, so junk in junk out. However, there's real intelligence in those systems.

It's amazing what they can find and explain. However, they shouldn't be a substitute for your providers but instead a way to prepare questions for the next time you meet them. For me personally, I've been getting much more information from AI than from my medical providers. Think of it this way, the AI can quickly scan millions of medical articles, research papers, etc. within seconds. My doctors only knows what's in their heads and so little research because they are booked with patients. I think once all doctors adopt AI as a tool, we should see the level of care quality increase. Or at least they will have more information at their fingertips.
