OpenAI GPT-6.1 Terra: Key capabilities

One of the main improvements in GPT-6.1 Terra is its ability to understand visual information and perform tasks using computer applications. OpenAI tested the model on professional tasks, including creating 3D models from architectural drawings and reviewing animated films to prepare time-coded reports.

According to the company, GPT-6.1 Terra scored 15 percentage points higher than GPT-5.6 Terra on the Agents’ Last Exam benchmark at medium reasoning effort. It achieved this with one-third the cost. OpenAI also said the model completed tasks more than three times faster than GPT-6 Astra and GPT-6.1 Sol.

The company has also worked to reduce factual errors. On its internal benchmark, the error rate at low reasoning effort dropped from 53.6 per cent with GPT-5.6 Terra to 16.7 per cent with GPT-6.1 Terra. At maximum reasoning effort, the error rate fell to 4.3 per cent.

GPT-6.1 Terra also brings improvements in software development. On the Terminal-Bench 4.0 coding benchmark, it solved 50.3 per cent of tasks at maximum reasoning effort, more than double the 21.5 per cent score published for GPT-5.6 Terra.

OpenAI noted that GPT-6.1 Sol and GPT-6 Astra remain better choices for the most complex coding tasks.
