Show HN: LLM Playground, compare results side by side (retool.com)

I was surprised by the quality of the results from Claude, I hadn't used it until recently. I asked it for strategic advice about playing a game of Magic: The Gathering and it gave what felt like pretty nuanced advice (talked about "resolving" spells, which is parlance only really used by avid players).

Nice work! I'm equal parts impressed and terrified that CSS can do this.

Does this use your own API keys? Several of the models basically don't load for me, and I assume it's being hugged to death.
