Lenny’s AI Builders

i looked at OpenAI's reported maths results, the GPT-6 Sol and Opus 5.5 price fight, Grok 4.7, Muse with Shopify and Qwen-Image-2.1. Then i gave Astra my existing LAB brand and asked for a matching thumbnail, banner and podcast cover. Astra directed the work in Codex; native ImageGen made the images. I show the finished set, the references and the checks. Give it your brand first. The maths result is OpenAI's claim, not an independently established result here. Some model details were reported or rumoured when this was recorded. Qwen's downloadable model needs suitable hardware. Threadify sponsors this episode.

What is Lenny’s AI Builders?

less scrolling. more “oh shit, i could use that”

i’m Lennox. five days a week, i dig through AI Twitter, pick the updates worth your time, and bring you one thing i’ve tested myself. what worked, what broke, and what you can try with it.

for people making products, content and useful systems with AI. you don’t need to write code to build something worth using.

each episode is under 15 minutes. grab the field notes for the prompts, steps and bits to watch out for.

this feed also keeps the earlier L E S S O N S episodes from my journey building with AI.
