Developer uses warm EC2 and Lambda fallback to beat 9-sec serverless chatbot timeout

By PulseAugur Editorial · [1 sources] ·

A developer has outlined a cost-effective method for integrating a chatbot into a website while adhering to a strict 9-second serverless function timeout. The solution involves running lightweight LLMs like GPT-4-All-J or Mistral-7B-Instruct on a continuously warm, low-cost EC2 instance. A Lambda function acts as a wrapper, forwarding requests to the EC2 instance and providing a static FAQ fallback if the inference exceeds the timeout. AI

IMPACT Provides a practical, low-cost method for integrating LLMs into web applications without exceeding serverless function limits.
