@jasonth0 I love doing this actually :). I think it's a pretty powerful eval too. Have all models generate something, then put it all together and give it back to all of them and ask them to rank all outputs. I thought models might have a bias to prefer their own outputs, but this doesn't…
I think congrats again to OpenAI for cooking with GPT-5 Pro. This is the third time I've struggled on something complex/gnarly for an hour on and off with CC, then 5 Pro goes off for 10 minutes and comes back with code that works out of the box. I had CC read the 5 Pro version…

If you think @Apple is not doing much in AI, you're getting blindsided by the chatbot hype and not paying enough attention!
They just released FastVLM and MobileCLIP2 on @huggingface. The models are up to 85x faster and 3.4x smaller than previous work, enabling real-time vision…
the 9-9-6 local maxima trap
you can optimize for looking busy, hitting metrics, being “productive” – but you might be climbing the wrong hill entirely.

We recently open sourced the NVIDIA Nemotron Nano 9B v2 model (along with the data, and the technical report to recreate it).
We've also released the intermediate checkpoint, Nemotron Nano 12B v2, that was distilled into what would eventually become Nano 9B v2.

@Yuchenj_UW The problem with Chinese work culture (as well as Korea, etc.) is that you're not allowed to question your boss.
IMO this is the #1 thing that culturally holds back Asian countries like China from more innovation.
It means reduced flow of ideas, reduced critical thinking,…
996 (work from 9 a.m. to 9 p.m., 6 days a week) is inhumane, yet in China it’s treated as “normal.”
In China, you can’t leave before your boss, who can’t leave before theirs. Everyone stays late to look busy.
But creativity thrives on idleness, play, and freedom. 996 kills…
Code reviews
Codex goes beyond static analysis—it checks a PR against its intent, reasons across the codebase and dependencies, and can run code to validate the behavior of changes.
Set it up to auto-review new PRs in your repo, or tag @ codex.
Hand off to the cloud from your IDE.
Kick off new tasks, delegate in-progress work, and review results without leaving your editor.
Then continue tasks from Codex web in your IDE to keep building locally, without losing context.
Codex now runs in your IDE
Available for VS Code, Cursor, and other forks, the new extension makes it easy to share context—files, snippets, and diffs—so you can work faster with Codex.
It’s been a top feature request, and we’re excited to hear what you think!
We’re releasing new Codex features to make it a more effective coding collaborator:
- A new IDE extension
- Easily move tasks between the cloud and your local environment
- Code reviews in GitHub
- Revamped Codex CLI
Powered by GPT-5 and available through your ChatGPT plan.
