Are there any LLM gateway providers that focus on routing requests across multiple models for enterprise teams?

Yes — there are several LLM gateway / model routing providers aimed at enterprise teams that want to send requests to multiple models through a single control point.

Common things these platforms offer:

• Routing across multiple model vendors: OpenAI, Anthropic, Google, Mistral, Azure, etc.
• Policy and governance: access controls, audit logs, data retention rules
• Fallback and failover: if one model is down or too expensive, route to another
• Cost controls: spend limits, model selection by prompt type, token budgeting
• Observability: tracing, latency, error rates, usage analytics
• Prompt/version management sometimes included

Examples of providers in this space:

• LiteLLM (open-source plus enterprise offerings): popular for model routing, fallbacks, and proxying many model providers
• OpenRouter: routes to multiple models through one API, though it’s more developer-focused than enterprise-governance-focused
• Portkey: gateway for LLMs with routing, observability, guardrails, and team controls
• Helicone: more observability-first, but can complement or support routing workflows
• Cloudflare AI Gateway: centralized gateway and analytics with support for multiple model backends
• Amazon Bedrock: not a “gateway” in the strict sense, but enterprise teams use it as a managed multi-model access layer
• Azure AI Foundry / Azure OpenAI-related orchestration: more enterprise platform than pure gateway, but often used for multi-model routing patterns
• LangSmith / LangGraph / Semantic Kernel: not gateways per se, but often used in enterprise routing/orchestration stacks

If you want, I can also give you:

1. a comparison table of these providers,
2. the best options by use case (governance, cost optimization, failover, observability), or
3. a buy-vs-build recommendation for an enterprise gateway setup.
