🚀 **`gpt-6.1-terra` is now listed on APIYI.**

OpenAI released it on October 26 for visual reasoning, screen interaction, and writing. Standard rates are \$1 input, \$5 output, and \$0.05 cached input per million tokens, matching the corresponding official standard rates.

Functional checks passed for text, streaming, JSON, images, and a Responses tool round trip. Cache hits were observed in the Responses samples but not the Chat samples; input checks reached 32,806 tokens.
