🚀Function Overview

A lower-cost GPT-5.6 preview option for teams that want to evaluate the family without paying Sol pricing on every task.

Key Features

Official OpenAI GPT-5.6 family member with model ID gpt-5.6-terra
Positioned by OpenAI as less capable and more cost-effective than Sol
Useful for staged evaluation before escalating to GPT-5.6 Sol
Official standard and batch token pricing published by OpenAI
Preview access can vary by account and rollout phase

Use Cases

•Cost-controlled GPT-5.6 family experiments
•Coding or analysis tasks that need more capability than a cheap baseline but do not justify Sol
•A/B routing between Terra, Luna, Sol, and older OpenAI models
•Preview API testing with explicit access and cost checks
