How I AI

Alex Cornell is a design director at Meta, where he leads design on Muse, Meta’s consumer AI agent. He came to the role with a long background in software product design, including time as a founder, and has spent the past year building one of the most thoughtful agent interfaces in the consumer AI space. Muse ships with a custom avatar, a three-layer status display, a personalized ideas surface, and a generative feed. Alex has been sharing the reasoning behind each of those design decisions publicly on Threads.

What you’ll learn:
Why Alex built Muse to feel like messaging, not an AI app
How Muse’s three-layer status system accommodates different levels of technical expertise
What generative UI actually means in a shipped consumer product
How Alex turned years of forgotten Instagram saves into a daily shopping catalog
Why his mom apologized to her Muse, and what it means for AI design
How he uses Muse to track his golf game, shot by shot, as he works toward a single-digit handicap
The mindset shift designers need when the output is never pixel-perfect
When to use the main chat versus a side chat, and where the architecture still falls short

John Lindquist created egghead.io, a developer education platform used by hundreds of thousands of working engineers. These days he’s building mega.dev, a hands-on program specifically for developers who want to do real work with AI agents, not just prototype them.

What you’ll learn:
Why Jev is a decision engine, not a chatbot, and what that distinction actually changes about how you build
How John built a real-time voice to-do app that classifies and executes commands with no visible pause
The data deduplication pattern that merges messy records in milliseconds using confidence scores
Why Jev works best as a router, and how a single text input can navigate users deep into an app
What a chess match between Jev and a low-reasoning LLM reveals about speed, cost, and when to use which
The multi-step classification pattern John reaches for when one Jev pass isn’t enough
Where Jev falls short, and when you should still reach for a full generative model

I spent the day at OpenAI’s DevDay in San Francisco, and I have good news and bad news: OpenAI released a lot of stuff.

In this episode, I break down the announcements worth paying attention to - and show you what happened when I tested some of them early. We’ll meet my Dot, explore why Spaces and Sites could matter for how teams work, and get into the model and API updates I’m most excited about as a developer.

I use the Decisions API to find podcast thumbnails where nobody looks awkward, build a collaborative sketchpad with Astra ultrafast, and let my kids redesign a 3D world in real time. That last experiment cost about $97. My wallet has thoughts.

These are my early impressions: what’s promising, what still feels rough, and what I think you should try first.

What you’ll learn:
What OpenAI’s Dots can do, how I’ve been using mine, and why I’m waiting to give a full verdict
Why Spaces might be one of the most underhyped announcements for collaboration between humans and agents
How Sites with connectors and plugins could help teams share internal tools with the right data permissions
Where GPT-6.1 Sol fits in my model stack—and why speed and cost matter
What vision adds to the Decisions API, including my thumbnail-selection and hot dog demos
What Astra ultrafast makes possible for interactive AI apps, from collaborative drawing to a changing 3D game
Where the speed feels magical, where the experience still needs work, and what it costs

(06:57) Spaces: working with humans and agents
(10:37) Sites, connectors, and sharing internal tools

Jev is TypeSafe AI’s new decision model. It returns type-safe structured values (a choice, a score, a probability) instead of generated text, at 4 cents per million input tokens with no output charge. This week I ran it on five real projects: PR categorization, a meta-analysis of my own Claude and Codex sessions, Gmail triage, the ChatPRD product insights graph, and a live audience dashboard built from 4,500 YouTube comments.

What you’ll learn:
What makes Jev fundamentally different from every other model I’ve used
How I analyzed 1,700 PRs for 9 cents and what I found out about where my engineering effort actually went
The personal meta-analysis you can run on your own Claude and Codex sessions right now
Why I stopped using Jev alone, and what I pair it with now
How I turned 4,500 YouTube comments into a searchable audience dashboard for almost nothing
The real-time app I built in an afternoon that shows something surprising about Jev’s speed
Why Jev’s pricing model is different from any LLM I’ve used, and what it makes practical to build
The ChatPRD product insights project: 1,100 signals, 200,000 classifications, and what it cost me
