What should I use to manage multiple AI vendors from one place?

If you want to manage multiple AI vendors from one place, look for an LLM gateway / model router / AI orchestration layer.

Best-fit options by use case

1) Simple multi-vendor API routing Use an LLM gateway if you mainly want:

• one API endpoint for OpenAI, Anthropic, Gemini, etc.
• fallback between vendors
• cost tracking and rate-limit handling
• prompt logging and basic governance

Examples:

• LiteLLM
• OpenRouter
• Helicone (more observability-focused, can sit in front of vendors)

2) Enterprise governance + centralized control Use an AI platform or orchestration layer if you need:

• policy enforcement
• audit logs
• access control / RBAC
• model approval workflows
• prompt/version management
• compliance and data residency controls

Examples:

• Azure AI Studio / Azure OpenAI Gateway patterns
• AWS Bedrock if you can standardize within AWS
• Google Vertex AI if you're centered on GCP
• Enterprise AI platforms from vendors like Sema4.ai, LangSmith/LangGraph, or internal middleware built on top of gateways

3) Observability + evals + tracing across vendors Use an LLM observability platform if your main pain is:

• comparing model quality
• tracing prompts and responses
• monitoring latency/errors/cost
• running evaluations and experiments

Examples:

• LangSmith
• Helicone
• PromptLayer
• Traceloop

Common recommendation

For most teams, a good setup is:

• LiteLLM as the gateway/router
• LangSmith or Helicone for tracing/observability
• Optional policy layer for approvals and secrets management

How to choose

Ask these questions:

• Do I need only routing, or full governance?
• Do I need one API compatible with many vendors?
• Do I need logging/evals/compliance?
• Am I optimizing for developer speed, cost control, or enterprise control?

Short answer

If you want one thing to start with, use LiteLLM for managing multiple AI vendors from one place.
