OPENAI UNVEILS PLANS FOR SEEMINGLY LIMITLESS EXPANSION OF COMPUTING POWER

OpenAI has laid out its vision for a $1 trillion build-out of computing warehouses across the US and abroad. It announced five new datacenter sites across the US, built with Oracle and SoftBank, which together will bring online nearly 7 gigawatts of power. The company envisions that it will need more than 20 gigawatts of computing capacity to meet demand for ChatGPT. Each gigawatt is expected to cost roughly $50 billion.

GETTING AI TO WORK IN COMPLEX CODEBASES

AI coding agents are great for new projects or small changes, but they often make developers less productive in large, established codebases. This post discusses a family of techniques called 'frequent intention compaction' that involves deliberately structuring how context is fed to AI throughout the development process to improve performance on large codebases. The technique has allowed a team to use AI to handle Rust codebases with 300,000 lines of code, ship a week's worth of work in a day, and maintain code quality that passes expert review. It shows how AI for coding is actually a deeply technical engineering craft.

CHROME DEVTOOLS (MCP) FOR YOUR AI AGENT

The Chrome DevTools Model Context Protocol (MCP) server brings the power of Chrome DevTools to AI coding assistants. It allows AI coding assistants to debug web pages directly in Chrome and benefit from DevTools debugging capabilities and performance insights. Use cases include verifying code changes in real-time, diagnosing network and console errors, simulating user behavior, and automating performance audits. A video showing how the Chrome Dev Tools MCP server works is available.

MICROSOFT LOOKS TO BUILD AI MARKETPLACE FOR PUBLISHERS

Microsoft's Publisher Content Marketplace (PCM) will launch as a pilot program with a limited set of publishers. The company's Copilot assistant will be the first AI buyer on the marketplace. Most AI companies have focused on brokering licensing deals that pay publishers upfront for access to content rather than on a per-use basis. PCM will help Microsoft deepen its relationship with publishers as it expands its AI capabilities and restructures its relationship with OpenAI.
