I code daily with AI - real programming tasks, professional, real work, read customers, I use below 3:
- codex 5.5 medium - best results less hand holding medium speed
- opus 4.8 max - mediocre with hand holding medium speed
- glm 5.2 max - mediocre with hand holding and super slow
- composer 2.5 - mediocre with hand holding and super fast
I use all, since i run mulitple coding in parallel.
disclosure - I use rexide which we created for all these agents to run in parallel with good visibility and feedback.
