OpenAI has introduced GPT-6.1 Terra, a new model in the GPT-6.1 family, with an announcement post and API documentation. In this episode we go through what OpenAI says Terra can do, how it is positioned and priced, and what the Hacker News discussion around the launch focused on.

Why it matters: every new API model changes the cost and quality trade-offs for developers building on OpenAI. If you are choosing a model for a product or an agent, you need to know where Terra fits next to GPT-6.1 Sol and Astra, and how it compares with other frontier and open-weight models.
