In May 2026, OpenAI quietly swapped the default model for ChatGPT to GPT-5.5 Instant. At the API level, this corresponds to a rather peculiar name: chat-latest.

xAI officially launched Grok Build in May 2026, and it has been the talk of the developer community for less than a week.

It includes performance benchmarks from OSWorld and Terminal-Bench, along with 5 typical application scenarios. Over the past two years, almost every "impressive" AI Agent demo has relied on a core capability: the…
If you're currently using Cursor as your editor for Claude Code, your experience likely looks like this: Cursor handles file management and code editing, while Claude Code runs heavy agentic tasks in the terminal. Occasionally, you run into those awkward "stutter + conflict" moments where they fight over file indexing, hog memory, or both the…
By the end of April 2026, Zed 1.0 was officially released. Built by the former Atom team using Rust, this editor finally stepped onto the mainstream stage after five years of development on GitHub. It isn't just another VS Code fork; it’s a "brand-new foundation" with a custom-built rendering pipeline and AI Agent protocol. It…
I recently received a classic inquiry: a user wanted to "distill" hundreds of thousands of words from a prolific writer into a Large Language Model to serve as a stylistic foundation, but they weren't sure how to feed the Markdown corpus in most cost-effectively. Three common approaches come to mind: uploading files one by one…
On May 14, 2026, Anthropic published "The Founder's Playbook: Building an AI-native startup" on the official Claude blog.

This article breaks down the manual…

This article provides a quick breakdown of what this means for AI developers and…
