Introducing Claude Code

Feb 24, 2025

We're launching Claude Code, our agentic coding tool, in a limited research preview. Claude Code lets developers delegate substantial engineering tasks to Claude directly from their terminal.

Claude Code has already become indispensable for our team. In early testing, Claude completed tasks in one pass that would normally take 45+ minutes of manual work.

With Claude Code, our goal is to better understand how developers use Claude to help improve our models for all.

In this demo, Claude Code completes complex coding tasks that would ordinarily take a significant amount of manual work. It explains an unfamiliar Next.js project, adds new functionality, creates tests, fixes build errors, and explains its changes.

Claude Code is all you need in 2026

Jan 14, 2026

Claude Code in 2026 is not what it was when it launched. After a year of building frameworks, custom setups, and elaborate systems to make AI coding work, we've come to a point now where... most of that is overkill.

In this video, I'll show you what building with pure vanilla Claude Code actually looks like in 2026. No frameworks. No custom rules. Just Claude Code with Opus 4.5 handling real professional development work.

I'll build a real feature in a real app, walking you through plan mode, the clarifying questions flow, and the native features that now do what frameworks used to do.

If you're just getting into AI-assisted development, or if you've been layering tools onto your workflow — this video will show you the simpler path forward.
