How do I update Python code that used a Line Code model?

Line Code ids stopped working on Nov 1, 2026. Swap the id and catch 410 so an old config can't break silently.

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.gateway.clatterlabs.xyz/v1",
    api_key=os.environ["CLATTER_API_KEY"],
    default_headers={"X-Clatter-Account": os.environ["CLATTER_ACCOUNT_ID"]},
)
import openai

REPLACE = {
    "line-code-fast": "supercosmos-flash",
    "line-code-ultra": "supercosmos-max",
    "line-code-ultra-fast": "supercosmos-heavy",
    "line-code": "supercosmos",
}
model = REPLACE.get(configured_model, configured_model)
try:
    r = client.chat.completions.create(model=model, messages=msgs)
except openai.APIStatusError as e:
    if e.status_code == 410:
        raise SystemExit("Retired model id in config: " + configured_model)
    raise

410 responses are never billed. Prices differ from Line Code; see prices.

The client setup above (base URL, key and the X-Clatter-Account header) is the same in every Python example; see Set up the Python SDK. Full parameter list: Create a chat completion.
