LangSmith LLM Gateway launches public beta for runtime controls in LLM agents

LangSmith LLM Gateway is now in public beta, acting as a central governance layer between agents and models to enforce runtime controls like spend caps, rate limits, model fallbacks, and sensitive data protections. These controls can be applied at Organization, Workspace, API key, and User levels, helping teams consistently govern model usage without vendor lock-in and preventing issues like cost overruns or outages.
