OpenAI has launched GPT-6.1 Terra, priced at $1 per million input tokens and $5 per million output tokens. This is half the cost of prior comparable models.[^1]

GPT-6.1 Terra has a documented 1.05M token context window, 128,000 maximum output tokens, and a June 1 2026 knowledge cutoff.[^2]

OpenAI determined existing model safeguards were sufficient to publicly release the model despite documented test findings.[^3]
