5 statements about GPT 5.1, every show
Willison: GPT-5.1 and Claude Opus 4.5 marked an inflection point for coding agents
“In November, we had what I call the inflection point where GPT, 5.1 and Claude Opus 4.5 came along and they were both just, they were incrementally better than the previous models, but in a way that crossed a threshold where previously, if you had these coding…”
McGrath: GPT-5.1 dramatically reduced token usage over GPT-5 while boosting evals
“Yeah, and so you can see, like, from five to 5.1, our overall evals, you know, we bumped some. But if you look at a two D plot of how many tokens it takes for us to get that, it went way down.”
Fioca: GPT-5.1 allows disabling preambles, unlike the reasoning-dependent Codex model
“So Five One, you can turn that off, you can prompt it not to do that, but the Codex model can't actually do that, and it relies on the reasoning summarizer to give you that update.”
Kaiser: RL is a major component in post-training tone steering
“I don't work on post-training and it certainly has a lot of quirks, but I think the main part is, is indeed RL where you say, okay, is this response cynical? Is this response like that? And you say, okay, if you were told to be cynical, this is how you should …”
Coogan: GPT-5.1 Widens Model Routing for Variable Reasoning Time
“I saw some charts that showed that it's more that they're just pushing the model router further to the edges, so it can Reason for even longer if it needs to, and it can reason for even less time if it just can come up with the answer quickly, more quickly.”
