GPT-6.1 Terra fixed all 20 bugs in my app for about $.06 a run GPT-6.1 SOL did the same for $.22 and opus 5.5 for $.78 GPT-6 Luna and Haiku 5.5 cost less but missed bugs in every run
GPT-6.1 Terra: delivering fast and capable computer use at a lower price. GPT-6.1 Terra understands what’s on screen, takes action across apps, writes naturally, and is a more capable model for your whole workday with the efficiency to take on more of it.

Haven’t read the thread, and I’m still sleepy, just woke up. But the premise that the “agent has to learn everything in the project from scratch” is false. It doesn’t need to understand the entire project to implement a new feature or fix a bug. This is obvious true, because much can be inferred from a single file from the interfaces it interacts with. And the more self-contained your files and modules are, the less context it needs. Of course, some tasks require a broader understanding of the codebase. But that can be rediscovered as needed. This is something I realized pretty early on. And it’s still one of the things I actively control as the human in the loop: I decide what context the agents get, and what they need to know. A well specified prompt will make the agent state whether more context is needed, but the agent can figure that out by itself anyways. I’d go further and argue that “knowing everything about the project” is detrimental. The underlying architecture is still the same, and everything in the context competes for attention. Things unrelated to the task injected into the context can only be detrimental.

The year is 2040. Robots do all blue collar work. AI does all the white collar work. Life expectancy is 125 years old. Drones keep humans in check.

for the community, i did my part today to save Astra demand: i removed my workflow skill for new tasks. the skill creates a branch, commits, runs tests, pushes changes, and adds comments to the ticket which is now a a make command. youre welcome. what have you done?

REMINDER: If you just walked into a university to study computer science and the curriculum doesnt include AI and/or agentic coding, LEAVE THAT UNIVERSITY.

This is GPT-6 Astra. Anything you can do on a computer, Astra can do for you. Fast.

Local developer agentic setups are going to have to end in team environments. There’s going to have to be a single team harness. The code coming out of multiple developers laptops is wildly different. I typically see 1-2 devs with a good setup
