Dialogflow vs ChatGPT

I have seen many people ask if ChatGPT makes Dialogflow irrelevant (or something to that effect).

But they are not just very different tools, they also target different audiences in my opinion.

Here is a comparison:

Dialogflow	ChatGPT (OpenAI API)
Can only answer questions defined in your intents	Can answer nearly any question
Need to provide a lot of training phrases	Fairly good question answering ability out of the box, but may not be best suited for your business domain
Will not hallucinate in its response (Generative Dialogflow CX is an exception)	Sometimes does hallucinate in its response
Easier to measure accuracy	Harder to measure accuracy
Easier to improve accuracy	Quite hard to improve accuracy
Easier to use for non-programmers	Much harder for non-programmers to use

Some additional notes:

For generative tasks, Generative Dialogflow CX is decent but not as good as OpenAI API.

Non-programmers can train Generative Dialogflow CX to perform information extraction. This is not easy to do using ChatGPT API.

To summarize:

ChatGPT is much more powerful than Generative Dialogflow CX

Dialogflow CX offers a good tradeoff between ease of use and power.

In some scenarios, Dialogflow ES is sufficient (and nearly free since it has a very generous free tier)
