Your RTX 3090 ships with about half its prefill speed locked away.
@0xSero explains how, plus the 81GB model he runs on a base M4 Mac mini with a 3090 over Thunderbolt 5.
We also cover his hacked X account, the OpenCode hack, and why chips ship locked.

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.
I realised timestamps probably wont work during live premiere but should work after! – at San Francisco, CA
You can watch/listen to our chat
with timestamps at the premiere:
youtu.be/1LK-k3noEbY
or on x at ~9pm SF time
ok first time ive had a major issue with bb
> user : what next
> opus 5.5 high : 1000+ CLI bb Processes
might have to try @aicodeking IDE – at San Francisco, CA

only been up since the challenge started ! 🚀
but are we on track??
@grok please calculate
hand offs > forks
@grok debate 3 points each
+1 one-prompt @get_bb_app plugin
cross harness slash commands + bonus UI
Longform dropping tommorow at 9pm PT
Shortform coming throughout the week
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.
