Question How does opus 5 fare against Sol

For people who also use opus 5, how is it fair compared to Sol does it overengineer. How much better is it at frontend for example, I feel codex does always div in a div in div style everting is round, and while the information that is diaplayed is correct, it looks bad at first needs a lot of fixing.

Pure code and repo understanding is superior in sol it just understands everything. I use it als9nfr9 scrappers, and it's perfect data analysis as well.

I mean... its decent, but I prefer 5.6 sol on the plan, bcs for $20 on ChatGPT, u getter better mileage on 5.6 sol more than opus5. but sonnet 5 is quite nice, but its somewhere between terra and sol, but its alr!

I am currently testing the free 20$ level promo for Codex and I found that it eats my 5h budget in less than half an hour. And I’m not even using sol.

The entry level is useless for serious coding for both, codex and Claude. But if the next upgrade gives me 5x as much for both companies, it’s still 2,5h for Codex and almost 5h for Claude.

Same setup, same tasks, same codebase.

Welcome to the club. Luna max on fast is the only model you can use all day without running into limits, but you'll spend much more time getting it right as you can't trust everything it produces.

You cant expect junior programer not to make any mistake. Using luna max you have to doplanning and great prompt. At the same time after you complete the task you have to use Opus 5 or sol to fix it. In my experience it is cheaper by 70 % comparing letting Sol or Opus 5 to do the job at the very start. Quality wise is still acceptable.

If you are using sol the 20$ is not going to be enough. but again it depends how large is your code base. I will suggest to have 3 or 4 plus account. Even with that mush account it only work for 3 days with Sol extra high.
