Merge launches Gateway for teams managing LLMs on prod

Merge announced Gateway, a control plane for running LLMs in production, launching on March 31.

Gateway provides a single API endpoint that routes to multiple providers and handles provider switching via configuration.

The product centralizes API key management, budget controls, PII detection, and unified observability across vendors.

Gateway ships with Python and TypeScript SDKs and is compatible with OpenAI, Anthropic, and LangChain clients.
