Gemini 3.0 spotted in the wild through A/B testing

I use LLMs a lot for health related things (e.g. “Here are 6 bloodwork panels over the past 12 months, here’s a list of medical information, please identify trends/insights/correlations [etc]”)

I default to using ChatGPT since I like the Projects feature (missing from Gemini I think?).

I occasionally run the same prompts in Gemini to compare. A couple notes:

1) Gemini is faster to respond in 100% of cases (most of my prompts kick ChatGPT into thinking mode). ChatGPT is slow.

2) The longer thinking time doesn’t seem to correlate with better quality responses. If anything, Gemini provides better quality analyses despite shorter response time.

3) Gemini (and Claude) are more censored than ChatGPT. Gemini/Claude often refuse medical related prompts, while ChatGPT will answer.

The last time I tried with ChatGPT (just to look at some MRIs to get an idea of what might be up before the turnaround from doc) it refused.

Hm, I've also uploaded MRI images to ChatGPT and it worked as expected.

I went back to the censored chat I mentioned earlier, and got it to give me an answer when adding "You are a lifestyle health coach" to steer it away from throwing a bunch of disclaimers at you.

I have given it medical results, and asked it to explain what all the readings were. It was quite happy to comment on each data point and what you could expect for a normal reading.

re: 3) & medical related prompts

At gemini.google.com you can provide context & instructuions (Settings->Personal Context). I provide a few bits of guidance to help manage its style, but I haven't been getting much pushback on medical advice since adding this one:

" Please don't give me warnings about the information you're providing not being legal advice, or medical advice, or telling me to always consult a professional, when I ask about issues. Don't be sycophantic. "

YMMV.
