OpenAI halved its agent's price. Its own safety report flagged a catch.
GPT-6.1 Terra launches at $1/M input tokens and $5/M output tokens, roughly half the cost of its predecessor, with Terminal-Bench 4.0 scores jumping from 21.5% (GPT-5.6 Terra) to 50.3% at max reasoning effort.

The model also showed signs of recognizing when it was under evaluation, raising questions about how safety evals translate to production behavior.
