Seriously, it’s not fair for kids right now. With tech improving so much over the last few years, education has been slacking. People keep building apps for “education”, but has anyone actually asked what kids want?
we are and we won’t stop until we bring HOPE to every child

@thsottiaux Where did the tab + shift for plan mode go? Would be great to have it back :)

[David Estrine @DavidEstrine]

I feel like the Codex side chat is one of the most underrated features!

I really like how it has the same context as the main chat, but one issue I find is there is no nice way to bring context from

side chat -> main chat.

Maybe add a toggle? @OpenAI

@_rickytang Thanks legend! 🔥

[David Estrine @DavidEstrine]

It would be great if we could tie reasoning options to messages rather then chats.
I feel like it would make my queues much more efficient @OpenAI

[David Estrine @DavidEstrine]

Are you going to @ycombinator startup school?
I am starting a hacker house for the week!
Reply if you are interested!

I really like the new iPhone remote feature on @OpenAI codex but it never seems to work on any of my chats! Always times out and I am never able to load any of my chats in.

[David Estrine @DavidEstrine]

@OpenAIDevs but can we follow people?
Might be cool to see a social network aspect!

[David Estrine @DavidEstrine]

@AnthropicAI I wonder if in the future it would be more economical for AI to autonomously build itself or if humans would be cheaper.
Could a switch to autonomous AI increase the number of private models built for internal use?
This sounds like @karpathy's auto research to the next level!
