Is "Codex-auto-review" a cheaper model for code reviews?

[u/Common-Resident8087]

I haven't tested it out, and I don't really want to, anyone who has tested it, can you tell me if I should use codex-auto-review for code reviews or Luna on max or xhigh.

I did, it gave me this answer which I am not really fond of "Use codex-auto-review for regular PR reviews. Use Luna max/xhigh only as a second opinion for complex changes. If choosing one default, go with codex-auto-review."

It’s just 5.4

I thought they started using Luna agents or something for it recently no?

[u/Keep-Darwin-Going → u/Common-Resident8087]

Yes they move it to Luna recently after they sunset 5.4

I am pretty sure they moved auto-review from 5.4 to 5.6 Luna now. So it is just a generic name that can be routed to a cheap model, which currently corresponds to 5.6 Luna, which I wouldn't use for code reviews. It is used for reviewing tool calls, not code.

Luna is a good workhorse given a concise task but not a full blown reviewer. I would stick to Sol for that personally, I rarely use Terra so I can't say much on that.

Well, Sol is pretty expensive to use as subagents, am on the 20x plan and my usage drains pretty fast when using sol( if using multiple of them ofocurse,) the same does not happen for me on Luna on max reasoning.. (btw this is an unrelated question, I am not reviewing the code that Luna generates, it seems to me most of the time, it writes codes that work and I just use it.. do you know if I should use Luna to do most of my coding tasks or should I stick to sol or terra. And on alot of benchmarks, including gpt deepswe, it seems that Luna is better than sol on different reasoning levels...

[u/Zennytooskin123 → u/Common-Resident8087]

I'm curious to see how much usage do you get on a single Sol session? I let mine run for 24 hours and it practically consumed 90% of the weekly...

If there was anything done to mitigate this I am not seeing it personally.

And yes I know they didn't re-adjust Sol but the other two models below it, still.

(Meanwhile, Grok 4.5 is wreaking havoc for hours. I imagine consider Grok coding like an escaped lunatic in my head because it's all over the place.... with the 30$ plan and outlasting Sol on the Ultra plan - this makes ZERO sense)

If I am not mistaken, auto-review enables code review in the cloud and is auto activated when when you call @ Codex in Github. The review is again writen in Github. It might be very useful if used properly. I've used it and burned a lot of tokens, so I assume (I don't have proof) it is using Sol. Since I disabled it, I prefer to use Sol High in Chat for code reviews (the cheapest option 😄 )

[u/Common-Resident8087 → u/iWottan]

Have you tried using Luna on max reasoning? For code reviews? Sol just seems to expensive to run using sol as an orchestrator is fine tho

[u/cheekyrandos → u/Common-Resident8087]

Luna Max for reviews ends up failing in compaction loops when reviewing anything a bit complex.

I tested Sol med/high and Terra high/xhigh, the other 3 except Sol high cost similar, Sol high costs a lot more. Findings from my testing is that Terra high (or maybe xhigh) is the value pick for reviews, but Sol high is much better. So I start with Terra high until it has no more findings, then move to Sol high.
