Have you taken a look at alting.ai? I tried it w/ #spring-ai and a paid plan. It serves popular models from a single OpenAI compatible endpoint.

* dep - add spring-ai-openai-spring-boot-starter in pom.xml or build.gradle
* doc - github.com/cf-toolsuite...
* config - github.com/cf-toolsuite...

Just got here. Is it truly a breath of fresh air?
