gpt-5.6-terra

The mid-tier GPT-5.6. Meaningfully cheaper than sol while staying in the same generation — a sensible default for agent loops and high-volume work.

Output	$12.00	$2.40	80%

Cached input is billed at a fraction of the input rate, so agent tools that resend the same context — Codex, Claude Code, Cline — cost considerably less in practice than the raw token count suggests.

What a real session costs

A coding session through Codex on this platform used 90,459 tokens across five requests — roughly seventeen minutes of back-and-forth over a codebase. At list price that is $0.178. The customer paid $0.036.

That is real billing data, not an estimate. Heavy context reuse is exactly where the saving compounds: the same work, one fifth of the invoice.

How to call gpt-5.6-terra

The API is OpenAI-compatible. Point your base URL at APICLAN and pass the model name — nothing else in your code changes.

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_KEY",
    base_url="https://apiclan.us/v1",
)

resp = client.chat.completions.create(
    model="gpt-5.6-terra",
    messages=[{"role": "user", "content": "Hello"}],
)

Using Claude Code or the Anthropic SDK? Those clients append /v1/messages themselves, so their base URL is https://apiclan.us with no /v1. Full setup for every client is in the Quickstart.

gpt-5.5	$1.00	$6.00

Prices above are what you pay, not list price. Cheaper models in the same family often handle routine work at a fraction of the cost — worth testing before defaulting to the largest one.
