Released by the vendor

Not a separate model: GPT-6.1 Terra with "reasoning": {"mode": "pro"} in the Responses API.
OpenRouter has listed it as openai/gpt-6.1-terra-pro since October 26, 2026.
Billed at GPT-6.1 Terra's standard rates; a pro answer uses more tokens, so the same question costs more.
Slower than standard mode. OpenAI recommends pro mode for difficult tasks that can tolerate higher latency.
