OpenAI presented the GPT-6.1 Terra model, which in performance tests significantly outpaces the GPT-5.6 Terra version. The new unit achieves results at the level of GPT-6 Astra, but requires only one tenth of its price per token and completes tasks on average more than three times faster. For developers and companies using autonomous AI agents, this means a substantial cost reduction with higher operating speed.
OpenAI presented the specifications of the GPT-6.1 Terra model in an announcement on platform X. The provided information indicates that the new version significantly outperforms the GPT-5.6 Terra model in the Agents’ Last Exam test. This benchmark assesses how effectively AI agents handle software in everyday work.
Higher Speed at Ten Times Lower Cost
The most interesting comparison is the new model against the existing high‑end variants. According to OpenAI, GPT-6.1 Terra matches the capabilities of the GPT-6 Astra model while costing only one tenth of the price per token.
The model also stands out in response time. Data published by the creators shows that GPT-6.1 Terra completes assigned tasks on average more than three times faster than both GPT-6 Astra and GPT-6.1 Sol.
What does this mean for users?
If you build applications based on AI agents or use them to automate software workflows, this change directly impacts costs and task execution time. A ten‑fold reduction in token price compared to the Astra model enables building more complex operation sequences without the risk of quickly exhausting the budget.
Meanwhile, the threefold acceleration of agent work means lower latency in ready‑made tools, which in practice simplifies automation deployment in scenarios where fast response time matters.
