GPT-6.1 Terra API
The mid-size GPT: fast and inexpensive for most tasks.
Good for
OpenAI’s models, from tiny Nano and Luna for bulk requests to Astra for heavy reasoning. They work with Codex CLI, the OpenAI SDK and any bot.
| Model ID | gpt-6.1-terra |
| Vendor | OpenAI |
| Family | GPT |
| Balance rate | ×0.5 / ×2.5 |
| Cache read | $0.005 per 1M tokens |
Requests longer than 272,000 tokens are billed at the vendor’s higher long-context rate, here too.
Both API formats
The model answers in the Anthropic Messages format and in the OpenAI Chat Completions format. Only the address and the key change.

How much does GPT-6.1 Terra cost on KLINCH?
$0.1 per 1M input tokens and $0.5 per 1M output tokens. OpenAI’s list price is $1 and $5. The balance is charged ×0.5 per input and ×2.5 per output token.
How do I call GPT-6.1 Terra through the API?
Use the KLINCH API address, your kl_live_… key and the model gpt-6.1-terra. The Anthropic SDK, the OpenAI SDK, Claude Code, Cursor and any client with a custom base URL work.
Is there a subscription?
No. You buy a token pack once and tokens are charged as you use them.
Is this the official OpenAI API?
No. KLINCH is not affiliated with OpenAI. We provide access to the model through our own gateway that speaks the Anthropic and OpenAI APIs.
One key, one balance, every top model
Claude, GPT, Gemini, DeepSeek and Grok at a tenth of the official price. No subscription, pay as you go.
