You:

Hey Iker, got a minute? I wanted to run something by you.

Iker:

Sure, what's on your mind?

You:

I've been thinking about open-sourcing the eval framework we built internally. It's gotten pretty solid over the last few months.

Iker:

Interesting. I see where you're coming from, but honestly, my first thought is maintenance burden.

You:

Yeah, that's fair. What specifically worries you?

Iker:

Once it's public, people file issues, expect responses, maybe even pull requests. We're not exactly staffed for that.

You:

There's definitely a trade-off there. But there's a recruiting angle too. Candidates could see how we actually build things.

Iker:

That's a good point, actually. It could also bring in useful feedback from people outside our bubble.

You:

Exactly. What about the security side? Any red flags there?

Iker:

We'd need to scrub any internal API keys and hardcoded endpoints from the config first. And legal would have to vet the license.

You:

Right, that's non-negotiable. What if we didn't open-source the whole thing at once?

Iker:

Go on.

You:

We could start with a stripped-down version, just the core evaluation logic, no internal integrations. See how much traction it gets.

Iker:

A phased approach. I like that a lot better than going all in. It's worth a shot.

You:

Great, I'll draft a proposal and loop in legal and security next week.

Iker:

Sounds good. Send it my way before you circulate it, I'd like to add a couple of points.

You:

Will do. Thanks for talking this through with me.

Iker:

Anytime. This could turn into something good.
