GPT-6.1 Terra API pricing
OpenAI · Mid-range price tier · Proprietary · released 2026-10. Prices in USD per 1 million tokens. Data snapshot: 2026-10-27.
A support ticket workload of 100K requests a month costs $400.00 on GPT-6.1 Terra; the next cheaper model in the Mid-range price tier for this workload, Palmyra X5, does it for $390.00. GPT-6.1 Terra has held the same list price since 2026-10-27 and is the 66th cheapest of 117 models in the Mid-range price tier. Only one host, OpenAI, sells it, so there is no second price to shop. No Arena score is published for it, so it carries no Efficiency score and cannot hold the FinOps Friendly badge.
- Input: $1.00 per 1M tokens
- Output: $5.00 per 1M tokens
- Batch API (in/out): $0.50 / $2.50 per 1M tokens
- Prompt-cache read: $0.05 per 1M tokens
- Context window: 1M tokens

Market position
On blended price ($3.80 per 1M tokens at 30% input, 70% output) it is cheaper than 42% of models in the Mid-range price tier: 66th cheapest of 117, tied with 2 others. Across every price tier it is cheaper than 26% of priced text models in the catalogue: 228th cheapest of 311, tied with 2 others. No Arena score has been published for GPT-6.1 Terra, so this page does not rank it on quality and OptimNow's quality bars do not apply to it. 65 of the 117 models we list in the Mid-range price tier carry one. An unranked model is unmeasured, not poor: the benchmark needs votes, and a recent release has not had time to collect them.
Licence, size and capabilities
GPT-6.1 Terra is recorded here as proprietary: access is through an API, priced by the token. Its parameter count is not published. Listed capabilities: Text, Vision, Reasoning, Agents. Filling its 1M context window once costs $1.00 in input tokens at list price.
Pricing by host
A host is a company that runs the model and sells it by the token: the model maker, a cloud platform like Amazon Bedrock, Azure or Vertex, or an independent host. One model, several hosts, and often several prices. This model is sold by 1 host. The price we quote elsewhere on this page is marked. We quote one host's rate so that models stay comparable; it is not a recommendation to buy there.
OpenAI is the only host with a published rate, $1.00 input / $5.00 output per 1M tokens, which is the price we quote.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| OpenAI (model maker, price we quote) | $1.00 | $5.00 |

Monthly cost at 100K requests, by business use case
From the after-discounts figure (prompt caching on the cached input share, batch API for async workloads, only where OpenAI publishes those rates), which assumes you implement both, to the list price. One figure means no discount is published.

It publishes a batch rate, and that discount is conditional: when the batch discount applies.
These are list prices. Your real cost also depends on caching and batching, negotiated discounts, marketplace agreements, and the contracts you already have. OptimNow audits exactly that.
