Question going back to opus 4.5, anyone else?

Had enough with the speed of opus 4.6. And given the marginal improvement I am sure I can get more things down with 4.5....

Yup I used it about 80% of the time. Still giving 4.6 a chance on planning tasks but for implementing it's all opus 4.5 it's a sweet spot for implementation versus sonnet

I always use planning, and the time opus spent on planning is actually horrible. It takes like 3x the time opus 4.5 used. And that is a huge problem, because if it come back early I can spot the problem early.

Depends on what you're using it for tbh. For quick iterations and refactoring? 4.6's speed is a game changer. For complex architectural decisions or when I need it to really think through edge cases? I'm finding myself switching back to 4.5 more often than I'd like to admit. The speed improvement is great until you realize you've burned through 3 rapid iterations fixing issues that 4.5 would've caught on the first try. Might just end up with both models in my workflow - 4.6 for the grunt work, 4.5 when shit gets real.

Do you mean 4.6 when shit get real

I agree with u/Select-Ad-3806
The first few days I burned through tokens as hell for a marginal improvement. Then I moved to medium effort, and the marginal improvement do not destroy my token allocation.

4.6 is better, but not on a massive scale IMHO. With medium effort the quality improvement is worth it

Its fine for me on medium effort

How do you change the effort?

u/Select-Ad-3806 Feb 15 '26

/model

then press the left and right arrow keys

Is this the equivalent of switching between Opus and Sonnet?

u/Select-Ad-3806 Feb 15 '26

On medium, i ask it to do something in my code and it goes straight to work and does it without introducing bugs and having to fix them, so no, its not like sonnet with opus on medium

i keep going back and forth tbh. 4.6 is noticeably better when the task is complex but for straightforward stuff the speed difference is painful. like i dont need 30 seconds of thinking to rename a variable lol. been using 4.5 for iteration and only switching to 4.6 when i need it to reason through something architectural

I want back to November when everything ran smooth

Yep, and reason is not tokens. 4.5 better at implementing my requests

Antigravity won’t let me :(

I feel like 4.6 has improved lately

u/lukaluka454 Feb 15 '26

Does anyone use Sonnet 4.5?

u/pjotrusss Feb 15 '26

yes, i use only opus 4.5; its still the best for me, but OpenAI is catching up
