Everything Bill Chen said on any show that made the record, most notable first. Each card names its show and opens the statement there.
Chen: Naming custom tools identically to terminal tools boosts Codex performance
“We found some, like, partners of ours, like, they discovered that what you can do is that you can actually still have a lot of the tools just named in the same way as the terminal tools, as well as having the same input and output. And all of a sudden, the too…”
Chen: Codex performs better when search tools are named 'rg' over 'grep'
“So if you call it grep, it actually does a little bit Worse. But if you call it RG, it actually does really well.”
Chen: AI agents will master GUI-based computer use by 2026
“And I can continue just by sort of like saying that that's definitely going to be something I think is going to be something that we'll be capable of in 20, 26.”
Chen: AI software abstraction is shifting from raw models to packaged agents
“So we're actually shipping this Entirety, entire agent altogether, then you can actually build on top of that agent. That's one of the patterns that we're seeing here is rather than focusing on optimizing with every single model release, you're actually just b…”
Chen: Terminal coding agents are actually general-purpose computer-use agents
“So what would you think about it is are those coding agents are actually a computer use agent, but for the terminal. They're actually incredibly general.”
Chen: Approximately 50% of OpenAI employees adopted Codex at launch
“Initially when Codex first launched, it was around 50% of folks that open AI started using it.”
