This. People keep asking me for my setup. It's really just any harness, multiple agents concurrently, barely any skills, and using adversarial reviews. There's no magic sauce (or source!). The models are great out of the box.

Day 1/
We have optimized the default speed to be ~50% faster across GPT-6 Astra and GPT-6.1 Sol through the subscription across all our products and partners using Sign in With ChatGPT (including OpenCode, Pi, Amp, Devin, ...).
No changes needed on your end and this should be felt within the next two hours.

turns out you can get indirect prompt injection to ~0 on unseen attacks if you stack enough layers (model training + input probes + a classifier checking intent). didn't expect that a year ago. auto mode is default in claude code as of next week

astra is a powerful model and we are working to make it generally available.
we do not think it is a good strategy to keep powerful models to a chosen few.
given its cyber capabilities, we need a little big longer to do do this safely. but hopefully not too long!

We just shipped a huge update to Claude's voice mode!
- Works with Sonnet and Opus models.
- Has access to connectors including Slack, Gmail, Notion, etc
- Can now speak in Spanish, French, Hindi, and more.
tl;dr, you can now ask things like
- Summarise what I missed in Slack over the last few hours
- Share a tl;dr of my new project PRD Google Doc, and send it to Nick in Slack
Huge shoutout to the team for all their work on this! And, as always, please send any feedback our way.

ChatGPT Voice is now in the desktop app.
Control your computer and direct multiple agents running in ChatGPT Work or Codex, using just your voice.
It's powered by GPT-Live, so it can speak, listen, and coordinate work in the app at the same time.
Rolling out globally today on macOS and Windows to Plus, Pro, Business, Edu, and Enterprise plans.

Claude Code on desktop now works with the iOS simulator.
Build and run your iOS app, and the simulator opens in a panel right next to your conversation. Available today in public beta.

My current loop:
Build something.
Ship it.
Talk about it.
Get ignored.
Learn why.
Improve it.
Ship again.
This is probably what building in public actually looks like.

Also adding to that:
I might not always be a distribution problem.
Sometimes you can have good distribution but you have built a product that doesn't solve enough of a painful problem for people to actually put in their credit card. So validation before distribution is also key.

If you think codex sucks at design, try "use imagegen to re-imagine this design and implement that".

Stopped chasing many tails. Stopped vibe coding all day. Focused in a big goal.
You should probably do the same... or you'll burnout. That's it, that's the truth.

Five books that genuinely changed how I think:
📖 The 4-Hour Workweek — Tim Ferriss
→ Question the default path.
📖 Sapiens — Yuval Noah Harari
→ See humanity from a much bigger perspective.
📖 The Creative Act: A Way of Being — Rick Rubin
→ Creativity is a way of living, not just making.
📖 The Almanack of Naval Ravikant — Eric Jorgenson
→ Wealth, leverage, happiness, and clear thinking.
📖 The Psychology of Money — Morgan Housel
→ Good financial decisions are more about behavior than intelligence.
