Gemini 3 Pro vs. ChatGPT 5.1 Pro vs. Grok 4.1 (and Codex 5.1 Max!)



Hey Reader,


What a week for AI coding! I have been diving deep into AI coding assistants and this week was incredible!

  • Gemini 3 Pro launched
  • Grok 4.1 is in beta (API somewhere?)
  • ChatGPT 5.1 Pro dropped (The best intelligence)
  • GPT 5.1 Codex Max launched

It'll take some time, but I have some early thoughts in the video below . . .

Want to see my workflow?

Watch my live demo with each of these new tools. It's unedited, so you'll see exactly how I work, and all the failure points. (Spider warning ... I show off my spider apps in this video)

video preview

I cover:

  • The best person to follow on X.com for AI coding
  • AI tools and agent.md rules
  • My AI workflow with Ghostty and codex CLI

This video is my first time using all of these new tools. I didn't plan anything other than trying to see if AI can solve this one tricky prompt. You'll see exactly what happens as we wait for code and test it live.

Want to learn with me on a weekly basis and finally publish your app on the App Store?

Join the waitlist for the App Launch Community here (ETA: January 2026).

I'll be showing what works and helping people in the community make huge progress towards their app goals. Join the waitlist if you want to learn how to sell a product and earn side income.

Danergous Spider App

I'm working on a dangerous spider app using Machine Learning (ML). If you're interested in learning about spiders, Core ML, Create ML, image classifiers, or image detectors, I can send you the beta.

Want to try the spider app beta? Reply and I'll send you the TestFlight beta invite.

I'm using AI to build all of these tools:

  • Import CLI tool (iNaturalist postgres)
  • Image Quality macOS app (Good/Bad)
  • Arachnid Detector macOS app (Test harness around ML models)
  • Macro Camera iPhone App (Macro photography + ML)
  • Crop CLI tool using my Arachnid detector

Codex is great for prototyping. It's way better than Claude Code (which is why you don't see that in the video). I used to use Claude Max, but stopped after it became super frustrating to use. (It lies about doing work or tests, so I can't trust it to finish tasks without babysitting 100%). Codex is more truthful and honest (not always, but overall).

Create ML - Machine Learning

Create ML is the training tool I'm using to create my initial MVP image classifiers and object detectors. It's Apple's harness for building intelligence into your apps. At some point that may change, but it's a great visual starting point. You can write your own training code in Swift when you need more control (which I imagine I'll be doing soon).

In the image above you can see a simple Object Detector model I trained on 914 spider images that I annotated with RectLabel (macOS). I plan to train a new model on 10,000+ images in the near future to improve accuracy.

Talk to you soon,

P.S. I help developers publish iPhone/Mac apps. If you’re interested in working with me on your next app, I’ll be kicking off a new group with weekly office hours. Join the waitlist for the App Launch Community here (ETA: January).

Super Easy Apps Weekly - Paul Solt

Join 5,712+ developers learning iPhone app development and App Store publishing. Every week, I share iOS tips on how to create polished, intuitive apps—backed by insights from shipping seven apps and working at GoPro, Apple, and Microsoft.

Hey Reader, This week is exciting. GPT-5.3-Codex launched today, so I put together a short video covering the five key updates (and a demo of what it can do). I didn't want to go back to GPT-5.2, after I got early access to GPT-5.3-Codex last week. The 5.3 model is faster and smarter. I can do more in less time. Watch here: GPT-5.3-Codex Launches Today — 5 Things You Need to Know The new Codex App + Plan mode + GPT-5.3-Codex helped make this video possible. Try it out and let me know what you...

Hey Reader, I had early access to Codex app this past week. The OpenAI team is moving insanely fast with Codex CLI, and watching this new app unfold was incredible. Take a look, and see for yourself. Download link in the video. Codex app feels like the missing IDE layer for the Codex CLI.One-click to open Xcode, run iOS/macOS apps, review diffs, and manage agents. I have mine configured using Makefiles (More on my setup in another email). Talk soon, Paul SoltPaul@SuperEasyApps.com P.S. Codex...

Xcode Build Failed

Hey Reader, AI agents struggle with iOS development for a simple reason: they can’t actually run Xcode. In this video, I have an impromptu conversation with Cameron Cooke from the UK about XcodeBuildMCP, a tool that finally lets AI build and run iOS apps in the Simulator. We talk through the backstory, the real problems it solves, and why this changes how AI agents work with iOS and macOS apps. If AI + Xcode is Broken for you, then you might need this tool.
