Just tried it out, withe some questions about ceramic firing in a electric kiln. Seems to have similar accuracy to chatgpt, maybe closer to gpt4.
It's not clear when using it what version it's on, so this may have been Claude 1, I'm unsure where to check.
I asked perplexity that same question. It kind of did better, it made no errors in temperature's like the others do. It just left those details out, initially. After asking follow-up questions it answered correctly, but also gave some unnecessary and unrelated information.
I didn't use any of the prompts, I was asking about saggar firing processes and temps, the prompts were just ceramics related.
