An OpenAI-compatible gateway is not exciting because it is compatible. It is exciting because compatibility lets you change the economic layer without changing the tool your team already likes.
That distinction matters.
A lot of developer infrastructure gets sold as if the feature itself is the point. "We support many providers." "We support many models." "We support many endpoints." Fine. But most developers do not buy a gateway because they want a prettier collection of provider logos.
They buy it because something hurts.
For Codex-style workflows, the thing that hurts is usually cost.
Once a coding agent is useful enough to become part of the day, it starts running constantly: repo scans, bug explanations, test generation, refactors, reviews, migrations, scripts. Some of those tasks deserve a premium model. Many do not.
An OpenAI-compatible gateway gives you a clean way to separate the workflow from the route.
The workflow can stay familiar:
OPENAI_BASE_URL=https://incat.ai/v1
OPENAI_API_KEY=sk_incat_your_key_here
OPENAI_MODEL=incat-smarter
The route underneath can change.
That is the practical value. You can keep the client shape and test whether cheaper model options are good enough for routine coding tasks.
The wrong way to use this is to chase the cheapest possible model for everything. That usually creates hidden cost because the developer spends more time fixing bad output.
The better way is routing by risk:
In other words, do not replace judgment. Price it correctly.
This is where inCat fits. It is a prepaid OpenAI-compatible gateway for developers who already like their AI coding workflow but want a smaller bill and clearer usage logs.

Keep Codex. Cut the bill.
