A lower-cost way to connect GPT applications
Compare an OpenAI-compatible API on the dimensions that matter: current model price, reliability, latency, limits, and how much code you need to change. Русский запрос: недорогой API GPT с совместимым endpoint и понятной оплатой.
OpenAI-compatible endpoint
Use the standard /v1/chat/completions endpoint with the official OpenAI SDK or any client that accepts a custom base URL. The same integration can be used from Python, JavaScript, cURL, Cursor, Codex, and other development tools.
from openai import OpenAI
client = OpenAI(
api_key="sk-your-api-key",
base_url="https://router.cheap/v1",
)
response = client.chat.completions.create(
model="gpt-5.6-sol",
messages=[{"role": "user", "content": "Reply with OK"}],
)A practical migration checklist
- Set the base URL to
https://router.cheap/v1and keep your API key in an environment variable. - Call
/v1/modelsto discover the models enabled for your account. - Compare output quality, latency, error handling, and total token cost on representative prompts.
When this route is a good fit
cheap OpenAI API guide is useful when you already use the OpenAI SDK and want to evaluate another provider without rewriting your application. It is also a useful starting point for prototypes where predictable usage-based billing matters more than a bundled consumer subscription.
Do not choose on a headline discount alone. Compare the same prompts, token mix, tool calls, latency targets, and failure recovery in a small test before moving production traffic.
Frequently asked questions
Is this an official OpenAI API key?
No. router.cheap is a separate API gateway. Use a router.cheap key and the documented base URL; do not paste an OpenAI secret into a third-party service.
How do I know whether it is cheaper?
Use the live catalog and your own token mix. Prices and model availability can change, so a workload-specific comparison is more reliable than a permanent cheapest claim.
Can I keep the OpenAI SDK?
Yes. Point the SDK at the router.cheap OpenAI-compatible base URL and select a model listed by /v1/models.
