If your goal is a smaller bill

Neither OpenRouter nor Vercel AI Gateway guarantees that your bill goes down. apicuts does: we switch on caching, routing, batching, and prompt and output fixes for you, and if your all-in cost isn't at least 20% lower after our 10% fee, you pay nothing. It uses the OpenAI API format, so it can also sit behind either of them.
