Not a new model: it's GPT-6.1 Terra with pro reasoning turned on.
Billed at Terra's rates, but each answer uses more tokens, so the same question costs more.
Slower than standard mode. Best for hard problems that can wait a bit.

Until it's on TeamoRouter, use these three

Same key, just switch the model ID.
