Control LLM reliability and spend from one place

Every model provider your engineering team integrates with comes with its own API,  rate limits, failure modes, and bill. 

This leads to fragmented routing, unclear spend, and inconsistent performance. 

When a provider goes down at 2am, someone gets paged. When costs spike, nobody knows which feature caused it. When sensitive data passes through a model, there's no record.

Merge Gateway eliminates this entirely. It’s a single integration point between your application and every model provider.

Routes every request to the right model. Gateway selects the best provider for every call based on the policies you set for latency, cost, and output quality. If your primary provider slows down or fails, Gateway automatically reroutes traffic based on your fallback settings or via intelligent routing.

Control your LLM spend. Set spend limits by team, project, or customer. Gateway tracks and enforces budgets in real time. Context compression reduces input size without degrading output quality, and semantic caching reuses responses for equivalent requests.

Log every AI action. Merge's competitors skip this. Gateway records every request with its routing decision, cost, latency, and policy outcome. When something goes wrong in production, you have a complete record of what happened and why. Merge CEO, Shensi Ding, shared "These are governance failures, not infrastructure failures." 

Merge isn’t new to this problem. AI-native startups, Fortune 500s, and leading SaaS and financial institutions already use Merge Unified to access hundreds of integrations through a single unified API, as well as Merge Agent Handler to give AI agents secure, scoped access to third-party tools. 

Gateway is the newest layer: one that makes model calls reliable, cost-efficient, and auditable.
