GPT-5.6 Terra Overview
GPT-5.6 Terra is the middle tier in OpenAI's GPT-5.6 family, designed to balance intelligence and cost for production workloads. It roughly maps to the mini tier from earlier GPT-5 families while retaining a 1,050,000 token context window, 128,000 max output tokens, image input support, structured outputs, function calling, and broad tool support for applications that need strong performance without flagship pricing.
