OpenRouter has listed OpenAI’s GPT-6.1 Terra Pro in batch mode. It uses the same underlying model as GPT-6.1 Terra, but sets `reasoning.mode` to `pro` for higher-quality responses on complex tasks.
OpenRouter warns that pro mode spends far more, but the listing gives no specific price. It shows a context length of 1,050,000 tokens.
Why it matters
For developers using OpenRouter, the listing offers a pro-reasoning option for complex tasks, but the unspecified higher cost makes the price of using it unclear.
