I don’t usually watch ChatGPT feature release videos because I find the just-sitting-around-a-table-chatting vibe a bit cringe, but I ended up watching Introduction to ChatGPT agent out of curiosity more than anything else.

As an agent, it does what you’d expect: accomplishing a task by running a virtual computer that controls multiple tools (text and web browsers, a terminal for running code). It looks capable enough (the primary example was planning a wedding trip; at one point, the agent realized it needed to understand “what does ‘black tie optional’ mean?” to figure out what type of suits to suggest), but what sparked this mention was the mini-demo at the end.

This demo starts at 22:44, where the presenters ask ChatGPT to build a plan to visit all 30 Major League Baseball parks in one summer. The agent pulls schedules, prioritizes day games, identifies the optimal routes between parks, and even highlights the best food in each park. It compiles a spreadsheet with all the information and generates a map.

I was gobsmacked. For the results, sure, but mainly for the topic itself. I’ve long aspired to visit all 30 MLB parks in a summer. I even bought and parked a domain name forever ago—BigLeagueRoadTrip.com—to document my progress.

That was 2016. The realities of work kept the idea for such an excursion firmly in the realm of pure imagination, but I recently started again considering what such a trip might look like—and again balked at the logistical nightmare it would be.

Now, a huge chunk of the work could be delegated to agentic software—accomplishing tasks that would take hours or days if done manually, but that can now be completed in seconds or minutes by software.

I felt like this demo existed specifically to convince me to use ChatGPT agent. If it was a micro-targeted drop-in, I wouldn’t be surprised.

Which might mean a legitimate shot at a Big League Road Trip in 2026.
