in codex - luna high for 80% of everything. This keeps me within the $100 a month plan. Then every so often Sol 6 high or even Astro xhigh but rarely. Also a lot of chat on xhigh or astro because that's billed seperate so I can have chat do a code review of what luna high just did and paste it to luna. Luna is always so embarrassed and agrees with the review.

gpt 5.6 sol. assuming the prose is similar with the gpt 6 series, if it was available at work that's probably what i'd be using instead.

i'm well aware of opus and fable's superior engineering qualities for writing code, however i find that as a swe who needs to understand every engineering decision that is made and is held accountable for their actions for safety critical code, understanding trumps speed every time.

and the gpt model series is far and above easier for me to understand the outputs of than claude, even with the prose improvements in fable 5.1 and opus 5.5.

luna for day to day tasks. opus for design / specs.
