OPENAI'S GPT-6.1 TERRA COSTS HALF AS MUCH — AND THE PRICE WAR IS ON

OpenAI's GPT-6.1 Terra costs less — a lot less. The company says its standard API prices are 50% lower than those of GPT-5.6 Terra and GPT-6.1 Sol.

The listed prices are $1 per million input tokens, $0.05 per million cached input tokens, and $5 per million output tokens, according to an AI week-in-review roundup of the October 26 to November 1 stories.

Terra was one of five AI stories that mattered this week for builders: a cheaper model from OpenAI, a security-focused one in Google's Gemini 4 Carbon, and an open-weights one in Mistral's Large 4, while Oracle announced plugins to connect its software to ChatGPT.

The thread through the week is a market splitting in three directions at once — cheaper, more secure, and more open — as every major lab tries to win developers before the next model cycle locks them in.

The caveat, as the roundup notes, is that this week's AI news is mostly vendors describing their own products: prices and benchmarks come from OpenAI and Google themselves, not independent tests.
