Model Gateway.

Route AI work through one governed model gateway.

An OpenAI-compatible gateway for local CLIs, hosted model APIs, and policy-controlled AI execution. Reduce token spend, preserve repo context, enforce controls, and capture evidence from every model workflow.

Capabilities

What Model Gateway does.

Cost-aware routing

Route heavy implementation, refactor, review, and test-fix loops through local CLI executors. Reduce direct API token spend on repo-heavy work without giving up hosted provider fallback when needed.

OpenAI-compatible interface

Your tools keep speaking the API shape they already expect. Route execution through Claude Code, Codex CLI, Gemini CLI, local models, or hosted APIs behind one endpoint.

Policy enforcement

Apply redaction, approval gates, model allowlists, rate limits, project rules, and secret-handling controls before prompts leave the workstation or runtime environment.

Local context leverage

Use local files, git state, terminal output, and repo-aware CLI sessions instead of repeatedly sending massive codebase context through raw API calls.

Fallback chains

Keep work moving when a model, CLI, or provider hits usage limits or latency constraints. Define ordered fallback chains across executors and providers.

Evidence capture

Log prompts, outputs, routing decisions, approval events, blocked requests, cost signals, and retest artifacts for audit, governance, and buyer security review.

Routing targets

One interface, many executors.

Keep the OpenAI-compatible interface your tools already expect while routing execution to the right target for each request type.

Policy modes

Control what leaves the environment.

Define per-route or global policies. Enforce them before prompts reach any executor.

Redact then allowStrip PII and secrets first

BlockReject with policy reason
Log onlyObserve without intervention

Evidence capture

Every model workflow leaves a trail.

The gateway logs routing decisions, policy events, approval actions, cost signals, and output traces. Export them for buyer review, auditor inspection, or governance sign-off.
