Aishwarya Naresh Reganti: evaluation

11 Jan 2026 Lenny's Podcast Why most AI products fail: Lessons from 50+ AI deployments at OpenAI, Google, and Amazon

“I mean, if you think of it's also the most beautiful part of AI, which is, I mean, we are all much more comfortable talking than following a bunch of buttons and all of that. So the bar to using AI products is much lower because you can be as natural as you would be with humans, but that's also the problem, which is there are tons of ways we communicate and you want to make sure that that intent is rightly communicated and the right actions are taken because most of your systems are deterministic and you want to achieve a deterministic outcome, but with non-deterministic technology and that's where it gets a little messy.”

Transcript context

…So let me give you a few more examples of this kind of progression that you recommend. And the reason I'm spending so much time here is this is a really key part of your recommendation to help people build more successful AI products. This idea of start slow with high control and low agency and then build up over time once you've built confidence that it's doing the right sort of work. So a few more examples that you shared in your post that I'll just read. So say you're building a coding assistant, V1 would be just suggest inline completion and boilerplate snippets. V2 would be generate larger blocks like tests or refactors for humans to review. And then V3 is just apply the changes and open PRs autonomously. And then another example is a marketing assistant. So V1 would be draft emails or social copy, just like here's what I would do. V2 is build a multi-step campaign and run the campaign. And V3 is just launch it A/B tested auto-optimize campaigns across channels. Awesome. Yeah. And again, just to summarize where we're at, just to give people the advice we've shared so far. One is just important to understand AI products are different. They're non-deterministic. And you pointed out, and I forgot to actually mirror back this point, both on the input and the output. The user experience is non-deterministic.People will see different things, different outputs, different chat conversations, different maybe UI if it's designing the UI for you. And also the output obviously is going to be non-terministic. So that's a problem and a challenge. And then- I mean, if you think of it's also the most beautiful part of AI, which is, I mean, we are all much more comfortable talking than following a bunch of buttons and all of that. So the bar to using AI products is much lower because you can be as natural as you would be with humans, but that's also the problem, which is there are tons of ways we communicate and you want to make sure that that intent is rightly communicated and the right actions are taken because most of your systems are deterministic and you want to achieve a deterministic outcome, but with non-deterministic technology and that's where it gets a little messy. Awesome. Okay. I love the optimistic version of why this is good. Okay. And then the other piece is this idea of this trade-off of autonomy versus control when you're designing a thing. And I imagine what you're seeing is people try to jump to the ideal, like the V3 immediately and that's when they get into trouble both. It's probably a lot harder to build that and it just doesn't work. And then they're just like, "Okay, this is a failure. What are we even doing?"…
