& LLM Guides
Practical guides on writing better prompts, cutting token costs and building with LLM APIs, for ChatGPT, Claude and Gemini users.
Exponential Backoff for OpenAI API Calls
How to implement exponential backoff with jitter for OpenAI API calls in Node.js, and why queue concurrency matters more than your retry formula.
AI Error Summarization for Node.js APIs
How to add AI error summarization to a Node.js API the right way: background queue, Slack alerts, and no blocked requests when OpenAI is slow.
Caching OpenAI API Responses in Node.js
Caching OpenAI API responses in Node.js with Redis: exact-match vs semantic caching, the real tradeoffs, and code that actually cuts your costs.
Fixing OpenAI API Timeouts in Laravel Jobs
OpenAI API calls timing out inside your Laravel queue? Here's why jobs fail mid-request and how to set timeouts that actually agree with each other.
Stream OpenAI API Responses in Node.js with SSE
Learn how to stream OpenAI API responses in Node.js using Server-Sent Events, with real Express code and the mistakes that break streaming in production.
