GPT-6 on xKiro — Sol, Luna and Terra

Three sizes of the new OpenAI family: flagship reasoning, everyday engineering, and a fast tier for volume. Same endpoints, same keys.

No end date announced

GPT-6 Sol, Luna and Terra now available on xKiro

About this offer

OpenAI's GPT-6 family arrives on xKiro in three sizes. Sol is the flagship for the hardest reasoning and long-horizon agent work; Terra sits in the middle for everyday engineering; Luna is tuned for speed on high-volume work. All three run through the same OpenAI-compatible and Anthropic-compatible endpoints as every other model on xKiro, with reasoning effort mapped automatically so an agent written for one family keeps working on another.
