GPT-5.6 Terra Pro

openai/gpt-5.6-terra-pro is GPT-5.6 Terra served with reasoning mode set to pro, for higher-quality answers on complex tasks. It spends far more reasoning tokens than standard Terra, so use it where answer quality matters more than latency and cost. It has a 1,050,000-token context window and a 128,000-token maximum output, takes text and image input, and answers in text, with reasoning, streaming, and tool calling. Nous Portal lists it at $2 per million input tokens and $12 per million output tokens.
