**It’s been one year of building with Claude Code, and we’re celebrating with a virtual hackathon and a ****[birthday party in SF.](https://cerebralvalley.ai/e/anthropic-claude-code-bday)**

Join us for **Built with Opus 4.6: a Claude Code virtual hackathon**!

**Opus 4.6 is our most powerful model yet**, and we want you to push the boundaries of what's newly possible. Whether you're creating agents, reinventing workflows, or solving problems we haven't even imagined, **show us what you can build in one week with Claude Code**.

We’ll select 500 participants and give each one $500 in Claude API credits to build for a week. **Compete to win $100k in Claude API credits** and the opportunity to share your project at [Claude Code’s 1st Birthday Party](https://cerebralvalley.ai/e/anthropic-claude-code-bday?tab=guest-list) in San Francisco on February 21.

Judges include **[Boris Cherny](https://x.com/bcherny)**, **[Cat Wu](https://x.com/_catwu)**, **[Thariq Shihpar](https://x.com/trq212)**, **[Lydia Hallie](https://x.com/lydiahallie)**, **[Ado Kukic](https://x.com/adocomplete?lang=en)**, and **[Jason Bigman](https://www.linkedin.com/in/jason-bigman-a134a024/)** from the Claude team.
