Do you think this is redundant?

Doesn't ChatGPT already have its custom GPTs?

It's not redundant because of "GPTs", it's redundant because it's quicker and easier to find a pair of shoes (as in their example) by checking a few boxes for size, style, brand, price, etc, than having a conversation about shoes with a robot.

Looks like it provides embeddable widgets and an easy to use frontend?

By that logic almost all saas products and plugins are "redundant" if the bare functionality is available by developing your own.

Good point regarding that specific use case.

Do you see a situation where this tool would actually be worth using?

If you mean that specific site, I'm probably the wrong person to ask as I don't see the point of turning searches into conversations at all, which seems to be what it does.

As for what to train on where the response is not a chat but a specific answer, I'd say documentation/data where objectively correct answers exist, like programming, mathematics, technical howtos, or even more critical things like medical or legal services if there's at least one human professional checking and validating the output.

Using an LLM like ChatGPT is probably a lot easier, but I think it's better long term to train smaller language models for specific tasks. That way you're not tied to a costly service that can increase in price, censor you, ban you or just stop working one day.

You nailed it on the head. The company that delivers REAL EXPERTISE using an AI Chat format will end up EATING SEARCH ENGINES' lunch.

All of Google's E-A-T and YMYL initiatives are just ineffective ways of trying to gin up authority / actual expertise using a decentralized model
