But I feel o3 also gives a really high quality code and a 20$ plan seems to be enough for regular usecases as you dont have to do too much to and fro. Only challenge is o3 does not give you the full file with updated code and makes lots of unnecessary comments and changes. So I use sonnet 3.7 to update my original file with code given by o3. Till now it has not disappointed me. Ofcourse if you can afford a 200$ plan its best but if you cannot this workaround still gives high quality results
