How I AI

Anthropic just released Fable 5.2, their new frontier model, and I spent two days actually building things with it before recording this. I made an animated marketing video from a single tweet, assembled a pile of unboxed furniture using only blurry floor photos, and extended our CXO brand sprites into a full bug-defense game complete with a trailer. In this episode I walk through what impressed me, what fell down, and how I’m thinking about routing tasks between Fable 5.2 and Opus 5.5 going forward.

What you’ll learn:
What Anthropic launched with Fable 5.2 and Mythos 5.2, and when to reach for Fable instead of Opus 5.5
My pros and cons after a couple of days of hands-on testing
How Fable 5.2 turned a tweet and a brand book into an animated video that doesn’t look like slides
The geometry test every other model failed: assembly instructions for flat-pack furniture with no manual
How it handled a real re-architecture of ChatPRD’s product intelligence pipeline
Why I still wouldn’t let it design a website on its own
The 3D typewriter it built me, and how you can get access to the model

William Imoh is the founder of Hackmamba, a developer marketing company, and the creator of Mural, a real-time voice app he built to learn Norwegian after moving from Dubai to Norway. He has a chemical engineering degree, taught himself to code, and spent four years as a product manager, but he had never written a line of Swift. In this episode, William shows how he used Codex and GPT-Live to build Mural natively for iOS and Android, then walks through the Lord of the Rings–themed Grok Bot “fellowship” that helps him run a team of about 25 as a solo founder.

What you’ll learn:
The design prompt that made Mural look nothing like any other language app
Why 1,000 days of Duolingo left him unable to hold a conversation in Norwegian
What GPT-Live-1 costs per session and the latency threshold that makes or breaks a voice tutor
How he assigned every solo founder role to a Lord of the Rings character in Grok
Why he gave his agents access to everything across 15 open tabs, except one thing
What he still has to do himself after the models improved
Why the fear that keeps him up isn’t replacement—it’s dependency

Ezra Mechaber is a growth product manager at Figma whose goal is to be “lazy in the right places.” When he joined Figma, he found almost no one outside engineering using AI to get real work done, so he and a couple of fellow PMs turned his personal Claude Code setup into PM OS, a shared repo of 31 skills that every PM at Figma now uses. In this episode, Ezra walks me through his favorite skills, how he bug bashes with Codex, AutoXP—an automated growth PM that found a huge win on its very first experiment—and a real-time writing assistant he built with Jev.

What you’ll learn:
Why PM OS is a repo, not a product
The skill Ezra runs six times a day to tame Slack
How one repo keeps 60 to 70 PMs in sync
Why his bug-bash agent catches things he never would
How AutoXP runs experiments with one human checkpoint
Why Jev took over every meeting he was in for two weeks
What to do when you want to yell at your AI

I have personal-agent fatigue, so I ran the first How I AI personal-agent benchmark: Grok Bot, Dot, Muse, and Claude Duet across nine real tasks, from a Slack reply and a Sentry bug to a Figma thumbnail, inbox triage, a family newspaper, physics homework for a fourth grader, shoe shopping, and a ChatPRD launch video. I used computer use to operate them: Claude ran Dot, Codex ran the rest and scored the results live. Here’s the scoreboard—and which agent I’d actually trust for work vs. life.
