Gotta be the most confusing subscription in existence. I see like 5 different prices for this thing I pay for X Premium+ ($33/mo), and that gives me Supergrok Plus ($100/mo) included? Doesn’t include Bot though Cursor Ultra ($200/mo) and Supergrok Heavy ($300/mo) include Bot But I can upgrade from X Premium+ to Supergrok Ultra on the Bot app for $259.99/mo (less than Ultra by itself?)

Was excited to give Grok Bot a try, but saw it's $350/mo just to kick the tires. What's up with that @johnbai !?

@chrisbarber Stirred Not Shaken is definitely the sleeper hit. Weird opening hours (the owner splits his time between two shops a couple of hours away) but the cookies are fantastic

CSS + canvas animations with Fable are *dramatically* better One of the things Anthropic has RL'd into Fable is a frame stopper Build a Fable animation and you'll notice it adds a URL anchor system (ex. # t=3.66) so the model can reliably screenshot at specific times

What are your favorite scraping, anti-detect, and AI agent browser services? Eg: @brightdata, @browser_use, @browserbase, @nottecore Working on a report

@Medaiseo 1) if you’re an iCloud Relay user it’s helpful to know that depending on your country, it may be less randomizing than you think it is relative to other VPNs 2) if you’re in risk, it’s helpful to have another data point to key anonymous traffic on. In this case, lowering risk

You can detect if someone is using iCloud Private Relay super easily Apple publishes a database of their egress IP addresses and the entire world's iCloud Private Relay traffic exits through ~105K IPv4 addresses. I analyzed it and found some surprising stuff. Let's dig in:

@james_raftery Extremely cool idea. Love the concept of tying revenue to fraud rules directly and modeling it as protecting-the-upside rather than just the downside Did you do it with anything other than ASNs?

But iCloud Private Relay users can rejoice: its traffic is typically associated with *lower* levels of fraud because it requires having a valid Apple ID with a working credit card. So (good) fraud models treat this as a risk reducer, despite it being a VPN
