PromptLayer Bakery Demo

We recently built a demo website called Artificial Indulgence to showcase how PromptLayer works in a real-world application. It's a fake bakery site, but everything you see is powered by live prompts managed through PromptLayer. Let me walk you through how it all works. The Setup The bakery

Orchestrating Agents at Scale (OpenAI DevDay Talk)

Building dynamic UIs for complex agentic workflows used to take months of custom engineering—now it takes minutes. At OpenAI's DevDay 2025, the company unveiled AgentKit, a revolutionary toolkit that transforms how developers build, deploy, and optimize AI agents. This isn't just another incremental update; companies

How OpenAI's Deep Research Works

OpenAI's Deep Research can accomplish in 30 minutes what takes human researchers 6-8 hours—and it's powered by a specialized reasoning model that autonomously browses the web, reads dozens of sources, and produces fully cited reports. Deep Research represents a new category of agentic AI that

OpenAI RL Fine-Tuning: What you need to know and when you should use it

OpenAI dropped Reinforcement Fine-Tuning (RFT) in late 2024, bringing academic RL techniques to everyday developers—one AI researcher called it "RL for the masses." Unlike traditional fine-tuning where models memorize examples, RFT trains models through trial-and-error with rewards, creating a breakthrough moment for developers trying to squeeze better

What we can learn from Anthropic's System prompt updates

Claude's system prompts evolved through dozens of versions in 2024-2025. Each change reveals concrete lessons about production prompt engineering. Find all their system prompts here https://docs.claude.com/en/release-notes/system-prompts Let's read them and see what we can learn! This post extracts the patterns

Code World Model: First Reactions to Meta's Release

Imagine an AI that doesn't just autocomplete your code but actually understands what happens when code runs. That's the revolutionary promise of Code World Models (CWMs) — a new breed of AI that bridges the gap between pattern-matching and true computational reasoning. While traditional code AI learned

AI doesn't kill prod. You do.

I had a conversation with a customer yesterday about how we use AI coding tools. We treat AI tools like they're special, and something to be scared of. Guardrails! Enterprise teams won't try the best coding tools because they are scared of what might happen. AI

Building Agents with Claude Code's SDK

Run Claude Code in headless mode. Use it to build agents that can grep, edit files, and run tests. The Claude Code SDK exposes the same agentic harness that powers Claude Code—Anthropic's AI coding assistant that runs in your terminal. This SDK transforms how developers build AI

The first platform built for prompt engineering
