SAME MODEL · TWO BUYERSON A SUBSCRIPTION
6.5Claude Max · ChatGPT Plus · GLM Coding — flat rate, tokens don't bill
Luna is the family's smallest tier: fine for everyday backend and Laravel work, and Luna max even handled a six-hour backlog run, but commenters question its top-end accuracy and note it wasn't built to rival Opus 5.5. Flat-rate buyers will gravitate to Terra/Sol for heavy lifts.
ON PER-TOKEN API
8.5Enterprise / pay-per-use — $/1M, latency, token efficiency bite
The API story is the inverse: same price as GPT-5.4-Mini but smarter, efficiency scales proportionally with effort levels, it matched Claude's rocket-test result at ~150x lower cost, and devs call it their cost sweet spot. Cheap, fast, good enough for daily work — excellent per-token value.
