OpenAI is retiring the middle child terra. not that surprising tbh. most people gravitated toward either sol or luna anyway, with terra being stuck in a weird middle ground. and now that astra sits above sol, the lineup is much cleaner: > Astra -> top end tier > Sol -> strong general frontier tier > Luna -> fast, cheap three clear tiers makes way more sense than keeping terra around to fill the gap nobody cared about. RIP little terra though.
