Enterprise LLM gateway that routes, compares and monitors 200+ models through a single OpenAI-compatible API with zero markup.

Unified OpenAI-Compatible API: Access 200+ models for text, image, video, embeddings and speech from one endpoint and swap models without code changes.
Smart Auto Router: Routes each request to the best model based on cost, latency, throughput or output quality.
Automatic Failover: Retries across providers, fallback model lists and virtual model aliases keep applications running during failures.
Cost Control and Governance: Project and API key limits, member roles and access controls prevent spend spikes.
Model Council and Playground: Compare latency, quality and cost side by side and combine models to cross-check outputs.
Observability and Insights: Unified dashboards, activity logs, alerts and weekly Insights that rank cost-saving changes.
Self-Hosting: Run the full gateway in your own cloud so prompts, responses, logs and provider keys stay in your network.

An engineering team replaces several provider SDKs with one OpenAI-compatible endpoint to simplify integration.
A product team cuts LLM spend by routing simple requests to cheaper models and reserving premium models for hard ones.
A platform team keeps a customer-facing app online by defining fallback model lists across providers.
A finance-conscious leader sets per-project and per-key limits to avoid surprise bills.
A regulated enterprise self-hosts the gateway so prompts and provider keys never leave its network.
A developer compares candidate models for latency, quality and cost in the playground before shipping.
