Staying Under the Radar
Every AI provider (OpenAI, Anthropic, Google) imposes rate limits on their APIs. If your agent makes too many calls too quickly, it will be blocked. **Rate Limiting** in LangChain ensures your application respects these limits by queuing requests and using "Exponential Backoff" to retry after a delay.
Token-Based Limiting
Beyond simple request counts, we also implement token-based limiting. This tracks how many tokens are being sent and received per minute, ensuring you don't hit "Tokens Per Minute" (TPM) limits that are common in high-traffic enterprise environments. It is a critical requirement for any production-grade agentic system.
Conclusion
Reliability requires discipline. By implementing robust rate limiting in your LangChain applications, you protect your infrastructure from being blocked and ensure a consistent, uninterrupted service for all your users.
