CodeRabbit positions Luna as a low-reasoning first-pass lane for summaries and lightweight prechecks in review pipelines (a positioning recommendation, no Luna scores given).
Task: code-review | 2026-07-09 older than 90 days
Practitioner report coderabbit.ai - +
A r/codex poster switched their default from Sol high to Luna max for planning and brainstorming, with subagents on Luna xhigh and Sol high for plan review; says Luna medium is roughly on par with GPT-5.5 medium and as cheap as small models. Relayed secondhand; original not fetched.

In the same thread one user rated Luna Max the best of the 5.6 lineup for UI design, and another says Luna solved problems that GPT-5.5 xhigh could not (anecdotal).

Dissent in that thread: Luna Max loads very slowly versus Sol, and lower-tier models may falsely report Git operations as completed.
