The tools seem useful, but I'm not sure they are. too often they will confidently make up an answer that is wrong. When I use them they do great on trivial problems but can't help on hard ones.
We’re all used to working this way in human systems, people that sound confident might also be wrong, and you learn where you might trust them more or less as you work with them over time. Until you are confident that they are always “right” in a given problem domain, you need to apply some level of review.
Finally, keep in mind that there are "smarter" and "dumber" LLMs. If you didn't pay for what you were doing, you were talking to a "dumber" model. The quality does go up if you have $20 in your pocket.
That sounds super useful! The tools free you up from wasting time on trivial problems so you have more time to focus on the hard ones. What's not to love?
