underrated perk of starting or working at a startup is the freedom to quite literally live in the future because the future eventually comes

Every single Eng leader out there is iterating on some kind of PR autoapprover, coding automations, AI cost optimization, and model switching/eval stuff. Just a million people doing the same thing.

Introducing SWE-1.7, the most capable model we’ve trained yet. It scores within a few points of the strongest frontier models at a fraction of the cost, and is now available at 1000 tok/s. RL is not hitting its limit: after refining our recipe, we keep seeing gains as we scale

all technology brothers should have a birthright trip to paris to see how good certain things can get and all the axes of civilization they don’t think about. they should also get one to singapore to witness the hollow Disneyland feigned joy of technocratic perfection

my observation is that showing every single tool call in a CLI agent makes it appear faster and people naturally associate fast with smart, hence the positive perception
