OpenAI launched GPT-6.1 Tera.
It has not been updated for a long time, and is now a full space between Sol and Moon. Prices per million tokens (entry / exit): GPT-6 Luna – $0.10 / $0.50. GPT-6.1 Tera – $1 / $5. GPT-5.6 tera - 2 dollars / 12 dollars. GPT-6.1 Sol and Sonata 5.5 – $2 / $10. Opus 5.5 – $4 / $20.
By quality: Compared to the previous Terra. In coding 50.3% compared to 21.5%, the errors in provocative queries are 3 times less. against Sol. The maximum explanation is bypassed, and 3 times faster. Against Opus 5.5. Less than 5 points behind at a 5+ times lower price. Luna is still ten times cheaper. It remains for classification and easy extraction. It's designed for computer use, so it's fine for agents filling out forms and passing interfaces. And the $2/$10 Sonata now seems a bit pricey. We are waiting for an answer from Anthropit).
