OpenAI GPT-6.1 Terra,
a work automation model
Key announcement summary
- OpenAI officially announced GPT-6.1 Terra, combining precise computer control and visual reasoning to help with everyday work.
- Standard API prices are 50% lower than before, reducing the barrier to automating high-volume tasks such as invoice processing.
- At maximum reasoning effort, it achieved a 50.3% task-solve rate, more than doubling its predecessor.
OpenAI has introduced GPT-6.1 Terra, a work-focused model with stronger precise computer control and visual reasoning. What has improved over its predecessor, and what could change in everyday work?
Precise computer use and visual reasoning
GPT-6.1 Terra combines natural writing, precise computer use and detailed visual reasoning in a fast, efficient model. It advances on GPT-5.6 Terra and supports everyday work, from writing proposals and interpreting drawings to filling forms and editing video.
Standard API costs reduced by 50%
Standard API pricing for GPT-6.1 Terra was set 50% below GPT-5.6 Terra and GPT-6.1 Sol. This makes it practical to automate repetitive work at scale, such as reviewing incoming invoices and entering their details into accounting software.
Performance gains and lower error rates by reasoning effort
GPT-5.6 Terra and GPT-6.1 Terra performance comparison
| Metric | GPT-5.6 Terra | GPT-6.1 Terra |
|---|
| Tasks solved at maximum reasoning effort | 21.5% | 50.3% |
| Internal benchmark error rate at low reasoning effort | 53.6% | 16.7% |
At maximum effort, the error rate falls by 18 percentage points to 4.3%.
At maximum effort, Terra is more than three times as token-efficient as Claude Opus 5.5, while its price per token remains about one quarter as high.
At maximum reasoning effort, the cost per task was reduced by about ninefold.
Platforms and standard API pricing
At a glance
- ChatGPT Work and Codex: available to all Plus, Pro, Enterprise and Edu subscribers from the official announcement.
- OpenAI API: developers can connect using the gpt-6.1-terra model identifier.
- Standard API prices: $1 per million input tokens, $0.05 per million cached-input tokens and $5 per million output tokens.
For development teams automating work at scale
GPT-6.1 Terra supports everyday work from writing proposals to editing video while reducing standard API costs. It suits teams building practical automation and reducing the cost of repetitive tasks such as organising invoices and entering data into accounting software.
