> Sonnet 4.5 quality is about as low as I'm willing to go.

literally a 30 day old model and you've moved the "low" goalpost all the way there haha. funny how humans work

Yup - just like sibling comment said - my "low bar" is going to be whatever the best model is that isn't unreasonably costly/expensive.

Speed of model just isn't the bottleneck for me.

Before it I used Opus 4.1, and before that Opus 4.0 and before that Sonnet 4.0 - which each have been getting slightly better. It's not like Sonnet 4.5 is some crazy step function improvement (but the speed over Opus is definitely nice)

I think Opus 4.1 is still much better than Sonnet 4.5

If cost is not considered- absolutely. That being said sonnet 4.5 and using thinking where it makes sense feels like way more bang for your buck and usually good enough. I really don't use opus anymore

Yes? Because why should we settle for less now that it is available?
Re:Cursor Composer: Building a fast frontier model with RL by swyx on Wednesday October 29, 2025 @01:27PM (#45750168)
because engineering is the art of "good enough" and composer is clearly "good enough but a lot faster" which makes up for intelligence gaps in interesting ways

It's not good enough for a lot of us, though, clearly.

For me the bar for barely good enough is and always has been Codex. Before I found frontier models more trouble than they're worth. And there is still a massive amount of room to grow before I can genuinely say working with these tools is more enjoyable than frustrating for me and now I use them (and how I think they should work).

Not sure about parent, but my current bar is set by GPT-5 high in codex cli. Sonnet 4.5 doesn't quite get there in many of the use cases that are important to me. I still use sonnet for most less intelligence phases and tasks (until I get crunched by rate limits). But when it comes to writing the final coding prompt and the final verification prompt and executing a coder or a verifier that will execute and verify well it's GPT 5 high all the way. Even if sonnet is better at tool calling, GPT 5 High is just smarter and has better coding/engineering judgement and that difference is important to me. So I very much get the sentiment of not going below sonnet intelligence 4.5 for coding. It's where I draw the line too.
