The week-long developer event spotlights Codex and agentic AI tools, drawing attention from builders at the intersection of AI and crypto infrastructure.
OpenAI is throwing open the doors for its Build Week, a global developer event running from July 13 to July 21 that centers on the company’s Codex tool. Registration is live on Devpost, and the event promises live sessions, community meetups, and a competition with prizes including cash, OpenAI credits, and invitations to future DevDay events.
What Build Week actually involves #
The event kicks off with a live opening session at 10 a.m. PDT on July 13, featuring OpenAI figures like Greg Brockman, Thibault Sottiaux, and Corey Ching. From there, participants get a full week of programming that includes daily community office hours on Discord and OpenAI Academy sessions designed to help developers get up to speed on the platform’s capabilities.
The core ask is straightforward: build something using Codex. Projects will be judged on technical implementation, design, user experience, and effective use of GPT-5.6, the newer model that OpenAI is clearly eager to stress-test at scale. The submission deadline is July 21, with judging and winner announcements scheduled for August 12.
Registration and project submissions are handled exclusively through the Devpost platform at openai.devpost.com. The event targets a broad audience, from seasoned developers to students and first-time builders.
Why crypto developers should be paying attention #
OpenAI’s Build Week is relevant to the AI-crypto trend because of its explicit focus on agentic AI applications. The company has been intensifying its work on agent-centric tools in recent months, including Workspace agents and related platforms. Codex itself is positioned as a coding and workflow automation tool, precisely the kind of infrastructure that crypto developers are already using to build autonomous agents that interact with smart contracts and on-chain data.
