Daily recap for May 20, 2026

Today we shipped four new tutorials for small-business AI, along with a full benchmark suite for testing prompt injection defenses. Each tutorial comes with a downloadable project and a step-by-step guide — you can try them yourself.

New tutorials

AWS Bedrock Code Sandbox for SMB Financial Report Generation

Small business finance teams can now generate monthly reports just by describing what they need in plain English. This recipe uses AWS Bedrock to produce Python analysis code, runs it in an isolated E2B sandbox, and returns formatted PDF and XLSX reports. Cost controls prevent overspend, and an LLM cache avoids recomputing identical queries.

Built with AWS Bedrock, Next.js, 85 tests, 98.52% coverage.

OpenAI Voice Agent for Twilio Customer Support Calls

Handle customer calls without hiring extra staff. This voice agent answers incoming phone calls, classifies intent, and resolves common inquiries — billing, tech support, general questions — using OpenAI and Twilio. Per-call budget enforcement keeps costs predictable, and circuit breakers gracefully fall back to voicemail if a service degrades.

Built with OpenAI, Express, 89 tests, 98.45% coverage.

Perplexity Code Sandbox for SMB Data Reporting

Let analysts ask natural-language questions and get back safe, executed code. This sandbox has Perplexity generate Python or SQL scripts, runs them in a Daytona sandbox, and returns results with cost breakdowns. Safety controls kill runaway executions and repair malformed output before it reaches your data.

Built with Perplexity, Next.js and Hono, 128 tests, 94.81% coverage.

Cohere Reliability Suite for SMB Customer Support

A production-grade reliability wrapper for Cohere-powered support agents. It automatically fails over to Azure OpenAI when Cohere is unavailable, enforces daily cost caps, repairs malformed replies, and caches identical queries. Support conversations keep flowing even during provider outages.

Built with Cohere, Express and Next.js, 117 tests, 94.48% coverage.

Building blocks shipped

Prompt Injection Bench

A complete benchmarking toolkit for testing prompt injection defenses, available as nine npm packages. The core package provides TypeScript types and Zod schemas for a standardized attack taxonomy; the runner executes benchmark suites with parallel attacks and configurable timeouts; the CLI wraps everything for easy command-line use.
