Four Shorts went out today. The one I keep coming back to is Anthropic's report on its own agents. My AI picks, Q1 vs Q4 2026: every tool I picked in February has a replacement now, starting with Claude Opus 5.5 for coding. https://youtube.com/shorts/fM7M64APoFs Full breakdown with sources: https://www.500xengineer.com/blog/ai-stack-q1-vs-q4 Why your AI forgets: the context window has a fixed size, the oldest turns fall out first, and facts buried in the middle of a long prompt get missed. Put key instructions at the start or the end. https://youtube.com/shorts/zM5ENvPflRY Full breakdown with sources: https://www.500xengineer.com/blog/context-window Anthropic studied its own team: by August, the agents its employees direct logged 6x the hours of the people running them, and interactive sessions sat around 80% idle, waiting for human input. https://youtube.com/shorts/n7kmGI8K34E Full breakdown with sources: https://www.500xengineer.com/blog/anthropic-agent-hours Higgsfield's new Content Factory turns one "What if..." idea into a faceless explainer video, 15 seconds to 5 minutes long. https://youtube.com/shorts/bsbvDocEnSQ Full breakdown with sources: https://www.500xengineer.com/blog/higgsfield-explainers This week's question: if your agents spend most of their time waiting on you, what's the first part of your review loop you'd hand to another agent, and what would you never hand off? Drop your answer in the comments, then bring it to Wednesday's Live Build + Q&A at 12pm ET (Calendar tab).

One developer, Brandon Thomas, rebuilt seven Adobe apps (Photoshop, Premiere, Lightroom and four more) as free, open-source Rust apps, with Claude writing much of the code. They're early alpha, and he says so himself. My takeaway: understanding and rebuilding a focused app is now a one-engineer job. https://youtube.com/shorts/Q28ndwNzttw Full breakdown with sources: https://www.500xengineer.com/blog/artcraft-rea-app-cloning If you'd rather sell this than just watch it, the free Legacy App Rescue playbook in Service Playbooks walks through the offer step by step. Earlier today's Short, on how I make AI Shorts for about a dime: https://youtube.com/shorts/FDS0cHUUJqI It's Friday, so this is the wins thread. This week my stack moved to two Shorts a day on the 500x Engineer channel, eight since Tuesday. Your turn: what did you ship this week, and where are you stuck? Drop both in the comments, even if the win is small.

Anthropic just renamed the Claude plans. Max 20x is now Ultra (still $200/mo) and Max 5x is now just Max (still $100/mo). If you're a subscriber, there's nothing to do. The big change: verified Ultra accounts lose the 5-hour session limit. It's rolling out today, starting with most existing subscribers. Newer accounts keep a temporary limit until Anthropic verifies them. The catch: the weekly limit doesn't change. It's 10x Pro per week, plus a separate weekly cap for Fable. The old "20x" was per 5-hour session, so this isn't a cut. Quick check: open Settings › Usage. No "Current session" bar means you're verified. If you run Claude Code agents all day, you now budget the week instead of the 5-hour window. I'm spreading long runs across the week so I don't hit the cap by Wednesday. The Short: https://youtube.com/shorts/aKnnKzTb2FA Source: https://support.claude.com/en/articles/17728952-what-is-the-ultra-plan Are you on Max or Ultra, and is your session bar gone yet? Tell me in the comments.

Most people know they should post Shorts. Very few want to film themselves every day. YouTube now lets you skip that part: record one selfie, read a few lines, and it builds an avatar with your face and voice that stars in clips up to 8 seconds long. https://youtube.com/shorts/U_8Ft4ZzO6k Full breakdown with sources: https://www.500xengineer.com/blog/youtube-ai-twin Today's get-paid idea: run avatar Shorts for local business owners who will never film daily. A dentist answering one common question a day. A realtor sharing one neighborhood fact a day. Who buys: owners who know they should be on Shorts and don't have the time. What you deliver: a month of scripts written as 8-second beats, with the hook in the first line and claims you've checked. The owner records their own selfie, the avatar stays on their account, and YouTube's AI labels stay on every clip. How to start: make five avatar Shorts for your own channel this week, then show them to one business owner you already know. The free lesson "Make AI Videos That Don't Look Like Slop" in the AI Video Creative track covers the disclosure rules. Earlier today: why OpenAI sells AI instead of building every app itself. https://youtube.com/shorts/XkWmO2dO5tg Which local business would you pitch first? Tell me in the comments.

I run dozens of coding agents in parallel, and the slowest part of my day is now the pull request queue. So when Thomas Dohmke, GitHub's former CEO, launched Entire this week with a plan to replace the PR with agent-run review (he calls it Trails), I had to dig in. New long-form video: https://youtu.be/HDpCiIv_6C4 What's in it: - what Trails actually does differently from a PR - the math behind the "89x faster than GitHub" claim, and its footnotes - what it costs and how switching works - two ideas for getting paid with review agents Question for you: what's your bottleneck right now, writing code or reviewing it?
