MULTI-PROVIDER MODEL ACCESS
Built for AI developers
Practical gateway features for teams that want model access without provider sprawl.
One endpoint
Connect apps and AI tools to many model providers through a single RexLLM base URL.
Familiar SDKs
Keep OpenAI-compatible and Anthropic-compatible client code while routing through RexLLM.
Routing controls
Use configured providers, combos, and fallback chains to keep requests moving when capacity changes.
Provider coverage
Expose premium and alternative model sources from one operational surface.
Credential safety
API keys and provider credentials are handled through the app's secured auth and encryption flows.
Usage visibility
Track usage, request history, model access, balances, and plan limits from the dashboard.
Choose the right plan
Start with pay-as-you-go or use a subscription plan when your workload becomes predictable.
Pay as you go
20-30x lower API cost
Use shared provider capacity and only pay for usage instead of maintaining separate provider accounts.
Subscription
Over 50x lower API cost
Subscription plans can reduce effective API cost even further for predictable workloads.
