Nvidia now has a free API for GLM-5.2
GLM-5.2 is one of the best open-source coding models right now. No need to buy Z.ai's Coding Plan. Just use Nvidia's free tier. Nvidia's free tier is notoriously slow. Peak hours, you queue up and wait. But free beats nothing, and off-peak it's honestly pretty solid. build.nvidia.com/z-ai/glm-5.2

I stuffed an agent into an Android phone.
You've probably run into those short videos lately where an agent drives a phone around by itself. This one is called Mika, and it's a free open-source project. It's an Android app that works in the background through accessibility mode, so it can use pretty much any other app you have installed. Reply to someone on WeChat, scroll Xiaohongshu, drop something in a cart and check out. It finds the buttons by looking at the screen. There's no API to wire up, and it doesn't care what resolution your phone is. When it reaches a payment step or a captcha it stops and lets you finish. 🔗 github.com/wangzan101/Mika

My product went profitable, and something in me broke.
Someone on Xiaohongshu posted a while back that she sells phone keyboard skins she made with Codex. Eight, ten yuan a pack. Over a thousand a month. I've been at mine for months. October: a few hundred copies, $1,200 gross. Platform fee 30%, tax 10%, so 60% should have landed. It came to just over a thousand dollars. I still don't know how the math pulled that off. I have an overseas bank account. Once lost $500 to a wire transfer off one. I'd still tell you to take payout through WorldFirst: less hassle, lower fees. You can also get a Hong Kong USD credit card tied to it that spends your WorldFirst balance directly. Digital card is free. Physical is $4. Mainland purchases under ¥200 skip the processing fee, and right now there's 1% cashback.
