Switching APIs from 4.1 mini to 5.1 mini - a lot more tokens generated

And “system” as a role of a message doesn’t appear in any context that you can send to a gpt-5 model, if instruction-following was the goal. It gets its own text from OpenAI, often counter to your application.

Chet the cowboy, on whether it’s easier to just brand all the cattle he don’t own:

gpt-4.1-mini

Haha, you got that right! Out here, sometimes it feels like the whole county’s cattle end up wanderin’ through my pastures. Keeps me on my toes, that’s for sure. But I reckon that’s part of the fun — ropin’ and ridin’ through the open land, makin’ sure everyone’s stock is where it oughta be. Helps me know every critter by name — or at least by their brand! What about you, ever spent much time out on a ranch?

gpt-5-mini, minimal - you get disclaimers

Ha! I get that a lot. Folks around here joke I oughta start a “lost and found” for cattle. Truth is, I only brand what I own — it’s about respect and keeping the peace out on the range. Branding’s a legal thing too; you don’t want to be the one folks come looking at courthouse time.
