I turned one image of my AI cohost into two sprite sheets. ChatGPT image generated both from a single picture. I'm using them to animate him.

Another beatiful Sunny Day in SF. Just had a chat with @0xSero. He dropped so much knowledge and alpha. Video coming soon...

I used 2.2 billion tokens in one day. It was for Swyx's Kill My SaaS competition. I looped agents on conference scheduling software and had adversarial verifier agents check the work until it hit the target state. What is the most tokens you have burned in a day?

Help me pick the overlay style for my Sero interview. My agent rendered 14 options on the same frame, from a hacker terminal to a split-flap board. Reply with the name of your favourite and I'll use the winner.

After this chat I was inspired to take cyber security more seriously. Sero says he has an agent do a >daily routine check and audit of his home device/network. I am setting one up for myself now.

I built the same landing page 14 times to test 5 anti-slop design skills. 9 of them wrote the same headline. Two skills never ran until I named them in the prompt. Hallmark was the cheapest run and my favourite page. Which design skill should I test next?
