GPT-5.6 Terra

GPT-5.6 Terra sits in the middle of OpenAI's GPT-5.6 line, keeping the generation's 1M-token context, image input, function calling, and structured outputs while running at a lower rate than the Sol tier. It is the sensible default for production traffic that needs frontier-family behavior on most requests: assistants, coding help, retrieval over long documents, and structured extraction. Start here, then move up to Sol only for the requests that genuinely need it.

Quick start

Use any OpenAI-compatible client. Just change base_url and your key.

from openai import OpenAI

client = OpenAI(
    api_key="tl-xxxxxxxxxxxxxxxxxxxxxxxx",
    base_url="https://api.thalam.ai/v1",
)

response = client.chat.completions.create(
    model="openai/gpt-5.6-terra",
    messages=[
        {"role": "user", "content": "Hello from Thalam!"}
    ],
)

print(response.choices[0].message.content)
