Foundation models keep getting smarter. But as the gap between them narrows, the features that build daily habit are becoming just as important.

The pet was never just a pet

OpenAI shipped Codex Pets on May 1. Sam Altman, CEO of OpenAI, tweeted about it himself: “ok it’s not the most important thing we’ve ever done but i find it more useful than it seems on the surface.”

Why would the CEO of one of the world's most watched AI companies personally flag a feature he'd just described as a footnote? Because sometimes, the small things reveal where product experience is headed.

Codex Pets places an animated companion on your desktop that floats above open windows, surfacing real-time updates from the AI agent running in the background. Eight built-in options, plus a /hatch command to generate a custom pet from any image. Within hours of launch, the community had produced recreations of Clippy, Goku, and Patrick Star.  

Small feature. Real utility. Instant emotional pull.

It makes the product easier, more visible, and more enjoyable to live with.

Access is not adoption

Most enterprises have AI deployed. The question is whether people are building it into their daily work.

Access is not adoption. Many AI tools sit open in a tab while teams continue working around them. The budget is approved. The rollout is complete. The announcement is sent. But the habit never forms.

That’s the gap Codex Pets speaks to. It doesn't improve the model, but it keeps the tool visible without making it intrusive. Status updates surface at the edge of your screen. A click sends a reply. You stay in flow.

That's a product decision optimised for retention, not performance.

From capability to habit

Codex Pets is a small feature. But it points to something worth taking seriously.

The first principle: user experience is a retention strategy. A product that fits quietly into your day gets used more often. It does not need to shout for attention; it simply needs to be present at the right moments.

The second principle: the best AI investments aren't always the most visible ones. For reps and marketers building daily workflows, the more important question is whether the tool feels good to use on an ordinary Tuesday. Does it reduce friction? Does it fit around how you already work?

When AI capability reaches parity across the major players, the product that earns daily use is the one that feels best to live inside. For enterprise teams, that means the tools worth investing in aren’t just the most capable ones, but the ones your people will still reach for six months from now.  

Capability gets AI approved. Experience gets AI adopted.
