The layer / Models

LLM gateway, live

ModelRouter

An Anthropic-compatible gateway with no provider lock-in.

ModelRouter speaks the Anthropic Messages API and forwards each call to Claude, Gemini, a local Ollama model or Nvidia Cloud. Coding agents and internal tools keep working unchanged while the model behind them is chosen by policy.

Why it matters.

Agent tooling is increasingly built against the Anthropic API. ModelRouter lets an organisation adopt that tooling while retaining the freedom to run sensitive or high-volume work on other providers, or entirely on its own hardware.

Drop-in compatibility

Works with any client that speaks the Anthropic API, including Claude Code.

Multiple back-ends

Claude, Gemini, local Ollama models and Nvidia Cloud behind one endpoint.

Policy-based switching

Change the provider for a team, tool or time window with a single setting.

Unified cost view

Consolidated usage and cost across every provider in one report.

Where teams use ModelRouter.

Coding agents

Run Claude Code against the most suitable model for each task.

Data residency

Route sensitive workloads to a model hosted on your own infrastructure.

Overnight batches

Move long-running work to lower-cost models without touching the tooling.

How ModelRouter connects.
