## Detailed walkthrough ### [00:00](https://www.youtube.com/watch?v=enPbh_A5F7E&t=0s) The Origins and Growth of the Codex Ambassador Program
Pauline Narvas and VB open the conversation by diving into their favorite subject: community. Pauline reflects on the unique alchemy that happens when curious minds gather in one room, noting how early concept sketches turn into tangible projects, introductions morph into lasting friendships, and the entire ecosystem matures into a genuine community. Turning to VB, she asks about the origins and trajectory of the Codex Ambassador Program, which VB immediately flags as one of his favorite initiatives across OpenAI.
VB explains that the program began with modest, exploratory expectations: the team envisioned recruiting just 15 to 20 ambassadors around the world to host a handful of online and in-person gatherings. The fundamental goal was simply to bring the capabilities of Codex and the GPT-5 model series directly into the hands of practitioners. Over time, that initial grassroots experiment expanded dramatically into a worldwide network spanning over 150 ambassadors in more than 80 countries, collectively hosting upwards of 300 events. At its core, VB emphasizes, the mission remains focused on empowering tinkerers, unlocking creative potential, and showing developers the practical "art of possibility."

- **Original pilot size**: 15 to 20 ambassadors worldwide. - **Current program scale**: 150+ ambassadors across 80+ countries. - **Total community gatherings**: Over 300 events hosted both online and in person. - **Core model integration**: Centered on Codex and OpenAI's GPT-5 series models.

[01:49](https://www.youtube.com/watch?v=enPbh_A5F7E&t=109s) Memorable Moments: Metro Hackathons and Global Build Week
When reflecting on their most memorable community highlights, Pauline highlights a uniquely inventive meetup hosted by ambassadors in Kochi, India. Rather than convening in a conventional office or conference room, the Kochi organizers chartered and boarded an active, running metro train. The carriage was completely packed with developers working side by side on their laptops, writing code and bringing ideas to life using Codex while in motion. Pauline describes witnessing this mobile hackathon as a pure expression of grassroots community spirit, noting with excitement that it has since sparked a broader trend.
```mermaid flowchart LR accTitle: Build Week Global Activation accDescr: Flow diagram showing the release of GPT-5.6 triggering worldwide 24-7 events across major hubs.

For VB, the standout milestone was the global "Build Week" organized around the launch of the GPT-5.6 model series. Designed to give developers immediate, guided access to the new capabilities of GPT-5.6 paired with Codex, the initiative activated the full ambassador network and resulted in more than 60 events across a single seven-day window. VB recalls the exhilaration of checking Slack every morning to find round-the-clock updates and photographs from meetups running non-stop in Tokyo, India, London, and San Francisco. Seeing tangible products materialize within hours validated both the technical capacity of the models and the organizing power of the ambassador network.
- **Kochi Metro Hackathon**: Indian ambassadors ran a live coding workshop onboard a moving city metro train. - **Build Week trigger**: Celebrated and supported the release of the GPT-5.6 model series. - **Build Week output**: 60+ individual events held over the course of seven days. - **Key 24/7 event hubs**: Tokyo, cities across India, London, and San Francisco.

[03:47](https://www.youtube.com/watch?v=enPbh_A5F7E&t=227s) Building with Heart: What Defines a Codex Ambassador
Pauline praises the ambassadors as some of the most dedicated community leaders she has worked with, emphasizing that what elevates their work is that they consistently "build with heart" and pour genuine passion into every meetup and talk they coordinate. Asked what OpenAI looks for when selecting ambassadors, VB breaks down the essential criteria: first and foremost is deep curiosity and a willingness to question consensus reality, challenge existing workflows, and push contemporary AI models to their absolute technical limits. Second is a commitment to mentorship—bringing peers up to speed with rapid product releases while cultivating an approachable, inclusive environment where newcomers feel completely safe asking foundational questions.
Pauline reinforces this point by dispelling the misconception that an ambassador needs to be an encyclopedic expert on Codex before joining. Technical knowledge can be developed, but curiosity and a generous spirit toward helping others are the true prerequisites. The conversation concludes with an open invitation to developers and creators worldwide: regardless of location or experience level, everyone is invited to get involved, collaborate, and build alongside the global Codex community.
- **Core ambassador traits**: - Unbounded curiosity and an appetite to challenge assumptions about what software can do. - A drive to push frontier models to their limits. - Dedication to mentorship, education, and keeping peers abreast of new OpenAI releases. - Cultivating psychological safety and an inclusive environment for beginners. - **Key qualification myth**: Candidates do not need exhaustive, pre-existing mastery of Codex; curiosity and generosity with their time are the decisive factors.
