One API for many models, or one key per host

You can open an account with each host that has the best offer for a model you use. Or you can use one API that serves all the models you need. The first optimizes each price. The second optimizes your time.

Each host is a key to store and rotate, a balance or invoice to watch, a set of rate limits, and a terms page to read. Each is another place where a card can expire and stop production.

When a new model comes out, you repeat the search. Teams that use three or four models feel this quickly.

One API has one price for each model. It will not be the lowest listed price for every model on every day. On 12 Nov 2026, the lowest listed input price for Kimi K3 here was $0.182 per million tokens, and 18 hosts listed the model.

Compare that spread with what your team’s time costs. For small and medium volumes the difference in price is usually less than the cost of managing the accounts.

Split when one model carries most of your spending and a host offers it at a clearly lower price with the window and precision you need. Move that one model. Keep the rest together.

An OpenAI-compatible format makes this easy to reverse, since only the base URL, key and model name change.
