Suspected OpenAI "6.1 Luna" spotted in Arena; ex-Vercel dev defends cheap small models

- A new model believed to be OpenAI's "6.1 Luna" has been spotted in the Arena, with outputs looking weaker than the "Terra" codename (unverified).
- The original poster questions why OpenAI ships small models while competitors lead, hoping for a whole new frontier family instead.
- Ex-Vercel engineer Brandon Galang argues the opposite: frontier control brings brand halo and high-margin spend, but most real use cases just need cheap, cost-effective tokens — 99% of what he shipped at Vercel ran on Luna-class small models in prod.
