How to use GPT-6.1 Terra on OceanToken

Three steps from no account to a working request. The same key and balance work for every model in the catalog.

  1. Create an account and get an API key

    Create an OceanToken account, then create a key. One key works for every model your account can use.

    Get API Key 

  2. Add credits

    OceanToken is prepaid: add credits, and each request is billed from that balance. Your console shows the rate for your tier.

    Add credits 

  3. Call GPT-6.1 Terra from your code

    Point an OpenAI SDK at https://api.oceantoken.ai/v1 and use the model ID openai/gpt-6.1-terra. The code below sends one request.

    Get API Key 
    from openai import OpenAI
    # Your API Key from the OceanToken console
    client = OpenAI(base_url="https://api.oceantoken.ai/v1",
                    api_key="YOUR_API_KEY")
    reply = client.chat.completions.create(
        model="openai/gpt-6.1-terra",
        messages=[{"role": "user", "content": "Hello"}])
    print(reply.choices[0].message.content)

    Specs, request sample and alternatives in the docs 

GPT-6.1 Terra is the mid-tier model in OpenAI's GPT-6.1 series, priced below GPT-6.1 Sol.

GPT-6.1 Terra costs $0.90 per 1M input tokens and $4.50 per 1M output tokens. Cached input costs $0.05 per 1M tokens, and cache writes cost $1.25 per 1M tokens. Web search costs $0.01 per search. That is 10% off the official price ($1.00 per 1M input tokens and $5.00 per 1M output tokens), for every account. Prices as of November 5, 2026, charged per use to your prepaid balance; the console always shows the current price.

GPT-6.1 Terra has a context window of 1.05M tokens (1,050,000 tokens).

GPT-6.1 Terra supports tool calling, structured outputs, image input (vision) and reasoning. It takes file, image and text input and returns text.

Send requests to https://api.oceantoken.ai/v1/chat/completions with the model ID openai/gpt-6.1-terra and your OceanToken API key. The API is OpenAI-compatible, so an OpenAI SDK needs only the base URL https://api.oceantoken.ai/v1 and your key. The Responses API and the Anthropic Messages API (/v1/messages) work too. The same OceanToken API key works for every model your account can use. Full reference: docs.oceantoken.ai.

OceanToken is prepaid. Open Credits in the console, choose an amount and pay by card on Stripe's hosted checkout page (Link works too). Your balance updates a few seconds after payment. Have a trial code? Redeem it on the same page.

Purchased credits are valid for 12 months from the date of purchase. Credits from trial codes, promotions or gifts may have a shorter validity. All purchases are final and non-refundable, except where the law requires a refund. Section 6 of the Terms of Service has the details.

Not if the request never ran: a request refused for an insufficient balance or by a safety check, or one whose provider fails before returning any output, is not charged. A video job that fails releases the amount it held. If a request breaks off after the model has started producing output, for example a stream cut off part-way, you pay for the tokens that were processed and generated for it.
