I recently sat down with Lenny Rachitsky to discuss why AI Evals are becoming the most sought after skill for product builders.

As a bonus, we step through an end-to-end example of building an eval in a spreadsheet so everyone can understand. See reply for links.
I think it’s more like 99% 🤣 the 1% worked super hard on data modeling
This one is going to be spicy. 80% of the time I've seen a graph DB in production, it's been an overcomplicated mess (especially in AI applications).

In this talk, Jo and I will discuss when GraphDBs are overkill and when they actually make sense.

For technical domains especially, getting non-DSes involved in analyzing outputs is vital. It’s hard to build anything good without it bc v1s almost always have major fail modes. Finding the appropriate system design—let alone optimizing—requires a tight coupling of output analysis and system design
Can non-data scientists write AI Evals? The answer is nuanced and not just "Yes". @eugeneyan.com and I discuss this in the context of the "analyze-measure-improve" cycle from our course.

I've been eval pilled by @hamel.bsky.social . Everyone is all let's build some MCP servers and ship a minimal AISRE as quickly as possible. And I'm writing a design doc about how to build evals with @runme.dev so we can iterate rapidly on the AI

As genAI projects mature, proper evals are becoming table stakes for production deployment. But how do we evaluate probabilistic machines?

Looking forward to learning about the latest techniques and best practices from @hamel.bsky.social and Shreya Shankar next month!

@hamel.bsky.social & his wisdom on evals, error analysis, looking at your data is what we need. Here are his 10 Don'ts:
• Don't skip error analysis
• Don't skip looking at your data
• Don't gatekeep who can write prompts
• Don't let zero users be a roadblock
• Don't be blindsided by criteria drift
