GPT-6.1 Terra
Pricing Calculator
Estimate token cost for GPT-6.1 Terra, then compare the same workload with GPT-6.1 Sol. Calculations run locally in your browser.
Terra is $1 input and $5 output per million tokens.
At published standard token rates, GPT-6.1 Terra is half the price of GPT-6.1 Sol. It is designed for visual reasoning, computer use and scoped work; choose Sol or Astra when a harder task needs more capability.

USD per one million tokens, at published standard rates. Tool calls and regional processing may add separate charges.
| Token category | GPT-6.1 Terra | GPT-6.1 Sol | Terra difference |
|---|---|---|---|
| Input | $1.00 | $2.00 | 50% lower |
| Cached input | $0.05 | $0.10 | 50% lower |
| Output | $5.00 | $10.00 | 50% lower |
03 / DECISION
Choose the model for the job, not only the price.
Consider Sol or Astra for
- Ambiguous or long-horizon reasoning
- Complex software projects
- Tasks where quality has more value than token savings
- Workloads that need a larger capability margin
Cost note:
The calculator compares published text-token prices. It does not estimate charges for tools, images, search, computer use, regional processing, or an application’s own infrastructure.
04 / FAQ
GPT-6.1 Terra pricing answers
How much does GPT-6.1 Terra cost?
Standard token pricing is $1.00 per million input tokens, $0.05 cached input tokens, and $5.00 output tokens.
Is Terra exactly half the price of Sol?
For the published standard text-token input, cached-input, and output rates, yes. Your application’s total bill can still differ because tools and other modalities have separate prices.
Can I use Batch or Flex pricing?
OpenAI documents Batch and Flex pricing as 50% lower than standard token rates. Use the calculator switch to model the token-price difference.
Where do these prices come from?
They were checked against OpenAI’s GPT-6.1 Terra model page on October 27, 2026. Confirm current pricing before production deployment.
