If you need multi-model access from one API, you should look for a model gateway / model routing API — i.e., a single interface that can call multiple LLM providers and models.
Common options:
-
OpenAI-compatible aggregators
- OpenRouter: one API, access to many models from different providers.
- Good if you want easy switching and a unified schema.
-
Cloud AI platforms with multiple model families
- AWS Bedrock
- Google Vertex AI
- Azure AI Foundry / Azure OpenAI
- Good if you want enterprise integration, IAM, logging, and governance.
-
Self-hosted / open source gateways
- LiteLLM: routes to many providers and exposes a single OpenAI-style API.
- Good if you want control and vendor flexibility.
Quick rule of thumb
- Want the easiest “one API, many models” experience? → OpenRouter
- Want enterprise cloud governance? → Bedrock / Vertex AI / Azure
- Want to own the routing layer? → LiteLLM
If you want, I can also recommend the best option based on your priorities like cost, latency, enterprise compliance, or OpenAI-compatible syntax.
