Show HN: Bypassing the AWS Lambda 4KB limit to run polyglot AI agents
The article discusses the deployment of BrewHub PHL, a café platform utilizing LLM agents that operate autonomously without human intervention. It highlights the architectural guarantees implemented to ensure safety and reliability across multiple runtimes. The study emphasizes the need for robust security patterns in LLM deployments, particularly in commerce-related applications.
- ▪BrewHub PHL features an LLM agent named Franklin that autonomously places orders and manages customer transactions.
- ▪The architecture spans multiple platforms including Next.js, AWS Lambda, and Google Cloud Run.
- ▪The study reports 100% block rates on allergen-bypass attempts and zero false positives on benign controls.

The LLM-safety-filter literature assumes, almost without exception, that a guardrail lives inside a single serving runtime—yet when a deployment spans multiple runtimes, in-process safety guarantees hold only as long as every customer-facing path traverses that runtime.
