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.

## The facts

- The listed context length is 1,050,000 tokens.
- GPT-6.1 Terra Pro uses `reasoning.mode` set to `pro`.

## 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.
