This article explores a fantastic approach to improving user experience with Large Language Models (LLMs) by implementing Server-Sent Events (SSE) in FastAPI using Azure OpenAI. The design addresses latency concerns and potential timeout issues, ensuring a smoother and more responsive interaction for users. This is a crucial step towards building more engaging and efficient AI applications.
Key Takeaways
- •Implements Server-Sent Events (SSE) to enable "character-by-character" responses from an LLM.
- •Addresses latency problems and prevents timeouts in AI applications.
- •Demonstrates a practical application of FastAPI with Azure OpenAI for streaming LLM results.
