The GPT-5.5 API,25% cheaper.
The exact model OpenAI serves, running on Azure. Point your client at our base URL, keep the rest of your code, and pay less on every token.
Works with
from openai import OpenAIclient = OpenAI(base_url="https://www.draftworks.dev/v1",api_key="dw_live_...",)# nothing else changes
Cheaper, quick, and you can prove what ran.
Served from Azure
Same weights as api.openai.com, with less sitting in front of them. First token usually lands under half a second.
Typical streaming time-to-first-token from us-east. Don't trust the bar: every response ships its own timing in usage.latency_checkpoint.
Up to 25% cheaper
Every token costs less than OpenAI list. You start at 20% off and drop to 25% once you've bought $5,000 in credits. One credit is one dollar of inference.
Per 1M tokens.
Signed on every response
Some resellers quietly route you to a cheaper model. We can't. Each response is signed with Ed25519 over the model id and a hash of the exact bytes we sent back.
Check any response yourself, no account needed.
Proof you got GPT-5.5, not a knockoff.
When a reseller sits between you and the model, the response alone rarely tells you what actually ran. So we sign it. Every reply carries an Ed25519 signature over the model id, the token counts you paid for, and SHA-256 hashes of your exact bytes in and out.
Pull any receipt from GET /v1/receipts/{id} and verify it against our public key, in your own code or straight from the browser.

Nothing you send trains a model. We keep SHA-256 hashes and token counts for billing and receipts, and the Responses API store flag defaults to off.
One line to switch. 25% off to stay.
