LangChain has launched the public beta of LangSmith LLM Gateway. This centralized governance layer sits between agents and underlying models, aiming to solve critical production issues like cost overruns, outages, and vendor lock-in.
Key Features
- Cost and Reliability Controls: Set spend and rate limits, track usage, and configure model fallback policies across any model or provider.
- Sensitive Data Protection: Automatically redact sensitive data such as PII and secrets before requests reach the model provider.
- Avoid Vendor Lock-in: Offers a unified gateway compatible with both closed and open-weight models, giving teams the flexibility to switch providers easily.
