OpenAI shipped GPT-6.1 Terra on October 26, 2026, and the model carries a Critical cybersecurity rating under the company’s own Preparedness Framework, according to Help Net Security. The same release cut API prices to $1 per million input tokens and $5 per million output tokens, half the standard rate of GPT-5.6 Terra and GPT-6.1 Sol. That pairing is the story. A model OpenAI places in its highest cyber risk tier now costs less than the model it replaced.

Critical is the higher of two cybersecurity thresholds in the version of the Preparedness Framework dated April 2025. A model reaches it in one of two ways. Either it can, with tools, find and build working exploits for unknown software flaws of all severity levels across many hardened real-world critical systems with no human involved, or it can plan and run a new attack from start to finish against a hardened target given nothing more than a high-level goal.

Pricing: $1 and $5 per Million Tokens Changes the Threat Math

Standard API pricing for gpt-6.1-terra is $1 per million input tokens, $0.05 per million cached input tokens and $5 per million output tokens, per GetPack’s pricing breakdown. That is half the standard price of GPT-5.6 Terra and of GPT-6.1 Sol. API usage bills separately from ChatGPT subscriptions, so teams can track agent costs without touching seat licenses. For a look at how this rate stacks up against cheaper rivals, see our API price comparison of Terra, Haiku 5.5 and DeepSeek.
