Still mind-boggling how far we've come: > Ask in Slack > Watch a video > Merge on Github app All the friction is gone. Coding is like online shopping now: the larger display is nicer, but not required.

TL;DR: Droid finished 2x faster than Claude Code with less tokens.
This is why @FactoryAI is hiring EPD in SF only. We’re also hiring fewer engineers than before, even as growth continues, so there’s less need to hire in more markets. A top engineer can amplify their output by orders of magnitude with agents, whereas others would just multiply bad decisions and bad code faster. Many of our largest projects are already bottlenecked on a single engineer because the shipping pace is so fast. Adding more people often wouldn’t meaningfully speed up timelines.

GLM-5.2 was already fast, so technically this should be called faster
4 of the last 5 PRs I merged in the last 3 days were one-shots from a single Slack message. Slack has become the default interface for my job. We've set up enough guardrails (hundreds, from CI checks, lint rules, security scans, e2e/unit tests, automated QA) that shipping a bug is virtually impossible here. On the off chance the result is drifting off course, I can take over the live session from the app to steer it back into place. Just like FSD with a Tesla, but the default is auto-pilot. Most of the time I skip manually testing. I read the droid summary, skim the code, run the preview deployment, click around a bit, or just watch the GIF the QA bot records of itself going through the app. Last week I tagged Factory for a fix, and the PR was created, passed CI, approved, and merged in under 12 minutes. 1 min to spin up a sandbox, 3 min to code, 6 min for CI to pass and finally 2 min for review. The software factory is real, and it is here.
