I use Opus 4.6 Fast-mode. It produces significantly better results in my work than any Codex 5.3 tier.

Me too. It's great that my employer pays for it and there's basically no budget, because this configuration is 10x more expensive than the regular default Sonnet.

Rapid iteration would possibly make up for the drop in quality, but I can't afford to use fast mode as I'm a contractor and pay for my own AI usage :(
