Ask HN: Which LLM are you using to evaluate your ideas?

Question as in the title. Curious about your experience and which LLM helped you out the most without saying yes to everything..

I’ve started using different models for different stages.

GPT mostly for product direction and positioning discussions. Codex for implementation-heavy changes and large refactors. v0 more for landing page structure / UI iteration.

I still find product judgment and SEO decisions require a lot of manual thinking though.

I actually haven’t gotten to evaluating ideas yet I’ve been too busy asking each llm why they thought they would be best for the task. Just kidding

I use ChatGPT and Gemini and Claude in various ways in my workflow

I landed with Claude as my daily driver LLM. As it is still limited in some capacities I do also work with ChatGPT and Gemini where they give better results in specific circumstances.

I am mostly using Gemini, but that's a decision I made 2-3 months ago. I try my best not to hint at what answer I am hoping for/would benefit me, and I play devil's advocate as much as possible.

		I only use Gemini 3.1 Pro. In my opinion, it's is better/cheaper/faster. I'm not coding with it much.

For now, I'd say Claude. I tried to work with other LLMs such as Gemini, Codex, GPT and Grok(high versions), but still Claude (4.8) gave me the best outcome.
