For now, I'm planning to stick with Opus 4.5 as a driver in VSCode Copilot.
My workflow is to give the agent pretty fine-grained instructions, and I'm always fighting agents that insist on doing too much. Opus 4.5 is the best out of all agents I've tried at following the guidance to do only-what-is-needed-and-no-more.
Opus 4.6 takes longer, overthinks things and changes too much; the high-powered GPTs are similarly flawed. Other models such as Sonnet aren't nearly as good at discerning my intentions from less-than-perfectly-crafted prompts as Opus.
Eventually, I quit experimenting and just started using Opus 4.5 exclusively knowing this would all be different in a few months anyway. Opus cost more, but the value was there.
But now I see that 4.7 is going to replace both 4.5 and 4.6 in VSCode Copilot, and with a 7.5x modifier. Based on the description, this is going to be a price hike for slower performance — and if the 4.5 to 4.6 change is any guide, more overthinking targeted at long-running tasks, rather than fine-grained. For me, that seems like a step backwards.
- trueno 6mo ago> 4.7 is going to replace both 4.5 and 4.6 as in 4.5 is no longer going to be avail? F. ive also been sticking with 4.5 that sucks

- xstas1 6mo agoPromotional pricing? Are they saying that after the promotion, it will cost more than 7.5x??
- freely0085 6mo agoYup
- roygbiv2 6mo agoWell fuck that then
- d0gsg0w00f 6mo agoHmm, maybe they're discouraging copilot+Claude through pricing, nudging people to anthropic suite of tools. That sucks. I've been super happy with copilot+opus/sonnet.
- axpy906 6mo agoWhy not just use Sonnet?
- rectang 6mo agoI've used Sonnet a lot. It is not as good as Opus at understanding what I'm asking for. I have to coach Sonnet more closely, taking more care to be precise in my prompts, and often building up Plan steps when I could just YOLO an Agent instruction at Opus and it would get it right. I find that Opus is really good at discerning what I mean, even when I don't state it very clearly. Sonnet often doesn't quite get where I'm going and it sometimes builds things that don't make sense. Sonnet also occasionally makes outright mistakes, like not catching every location that needs to be changed; Opus makes nearly every code change flawlessly, as if it's thinking through "what could go wrong" like a good engineer would. Sonnet is still better than older and/or less-capable models like GPT 4.1, Raptor mini (Preview), or GPT-5 mini, which all fail in the same way as Sonnet but more dramatically... but Opus is much better than Sonnet. Recent full-powered GPTs (including the Codex variants) are competitive with Opus 4.6, but Opus 4.5 in particular is best in class for my workflow. I speculate that Opus 4.5 dedicates the most cycles out of all models to checking its work and ensuring correctness — as opposed to reaching for the skies to chase ambitious, highly complex coding tasks.
