OpenAI Launches GPT-6.1 Terra with 3x Faster AI Agents, 50% Lower Pricing
OpenAI said the midrange model is faster on office tasks and costs 50% less than GPT-5.6 Terra, while internal tests flagged security risks.
- OpenAI introduced GPT-6.1 Terra today, a new model designed to deliver substantial performance gains while cutting API costs to $1 per million input tokens and $5 per million output tokens.
- Terra bridges the performance gap between GPT-6.1 Sol and GPT-6 Luna, operating at roughly 50% the cost of GPT-5.6 Terra and positioning itself as a cheaper alternative without sacrificing quality.
- On Terminal-Bench 4.0, Terra solved 50.3% of problems at maximum reasoning effort, demonstrating performance nearly comparable to GPT-6 Astra despite the lower price point.
- OpenAI classifies Terra as having "Critical" cybersecurity capability under its Preparedness Framework, citing a 24.5% success rate in developing arbitrary-code-execution exploits during internal testing.
- Available today in ChatGPT Work and Codex, the lower-cost model aims to automate computer tasks and boost vulnerability research accessibility, though OpenAI acknowledges heightened safety vigilance is essential.
