I'm a happy customer. They provide a good service that saves me hundreds of tiny chunks of time during research. The instant ads hit, I'm out. Any distraction from the results is a time and mind suck which users like me will have no tolerance for. Thankfully, what they're doing is "only" as complex as driving searches with LLMs. And it probably doesn't even involve fine tuning, given that they're able to run new LLMs the same day they're released. I hope to soon be a happy customer of the natural open source replacement for this.
