Two community events back-to-back in Seoul. A snapshot of why Korean AI builders are no longer a regional story.
TL;DR
Two events, one weekend, one signal: Korea is becoming a major export hub for AI agent harnesses — the orchestration layer that sits between humans and frontier models like Claude, Codex, and Hermes.
Event | Date | Sponsor / Venue | Scale | Headline |
OmOCon Seoul 2026 | Held just before May 10 | Sponsored by Hashed | 15 speakers + crowd | Builder-first, no corporate keynotes |
Hermes Agent Community Meetup @ Seoul | May 10, 2026 | Officially sponsored by Nous Research / Hosted by Sionic AI | 1,000+ RSVPs | Official merch & hoodies shipped from Nous, signaling Seoul as a top-tier global hub |
OmOCon = oh-my-opencode conference. The first edition (~100 people) was held on March 28, 2026 in San Francisco. Seoul is the second.1. Who's in the room
Korean builders shaping the global agent stack:
Name | Project | Why it matters |
YeonGyu Kim | oh-my-openagent (formerly oh-my-opencode) — multi-model agent orchestration harness | Now joined Sionic AI. The spiritual anchor of the OmOCon series. 160+ contributors. |
Yeachan Heo | oh-my-codex, oh-my-claudecode (OMC) | The OpenAI Codex team is reportedly watching. OMC's mantra: "Don't learn Claude Code — just use it." Magic keywords like ralph, ralplan, ulw, autopilot. |
Woonggi Min | Co-author on the OMC line | — |
Junghwan Na | Ouroboros — Socratic-interview harness with ontology convergence (≥0.95) and ambiguity scoring (≤0.2) | Got 2M+ views on X for the GitHub-suspension-and-recovery saga earlier this year. |
Goobong Jeong | Ralphthon organizer, leader of Team Attention | Built around the Ralph Loop — long-running autonomous agent loops. The hackathon's signature rule: "Touch your computer, lose points." Humans write specs; the loop writes code. |
Junho Lee | Building an opencode-based harness from Busan | A non-Seoul builder hub forming. |
Austin Wang (YC) | Cmux — multitasking terminal | OmOCon Seoul 2026 speaker. Korean-American builder shipping from the YC orbit. |
Yuha Han | OpenAI Korea | The foundation-model side of the network. |
Seojoon Kim | Hashed — sponsor backbone | Hashed runs offices across SF, Singapore, Seoul, Bangalore, and Abu Dhabi. With EO, they're the capital + reach behind Korean builders going global. |
2. The Korea → global pipeline (Ralphthon case study)
Ralphthon is the clearest export path right now:- Seoul → SF → Singapore. OpenAI sponsors the SG edition; W&B hosts in San Francisco.
- Sponsor stack expanded to include Kakao, Naver, and OpenAI (per Seoul Economic Daily, March 2026).
- The signature "humans clock out, AI does the coding" rule was reproduced in the W&B SF office, with Alex Volkov (@altryne) helping host until 3 AM — a notable case of US influencers importing a Korean format rather than the other way around.
- Intellectual lineage: Karpathy's autoresearch experiment (700 self-directed runs, 11% training-time reduction on a GPT-2 baseline) is the zeitgeist backing for the Ralph Loop philosophy.

4. Four things that make this scene unusual
Pattern | Evidence |
Periphery-to-frontier inversion | A line that surfaced in the OmOCon recap: "There are moments when San Francisco actually feels slower than Seoul." |
Korea as a major harness exporter | oh-my-openagent, oh-my-claudecode, Ouroboros, opencode-based harnesses — Korea is supplying an outsized share of the global agent-harness layer. |
Nous Research's home-court treatment of Seoul | Official sponsorship + physical merch & hoodies shipped in. Seoul is among the first major global meetup cities after SF/NY for Hermes. 1,000+ RSVPs confirms the heat. |
Builder culture as antithesis to corporate keynotes | Demos and peer debate over one-way talks. Ralphthon takes this to its logical extreme with a "don't touch the keyboard" rule. |
5. Quotes from the moment
"Software is the prompt for the next version of software."
— Marc Andreessen (a16z), in an X post cited in the OmOCon recap.
"Beyond the for-vs-against debate, the real task is: how each of us, in our own seat, builds something meaningful with this technology."
— From the OmOCon Seoul 2026 recap.
"I believe a culture of openly sharing the joys and struggles of building, and cheering each other on with 'good work, that's impressive' — that culture makes the world a slightly warmer place."
— From the OmOCon Seoul 2026 recap.
6. What to watch next
- Aftershock from the May 10 Hermes meetup. Sionic AI hosts Park Jin-hyung — reportedly the world's #1 Claude Code token consumer (~1.5B tokens). Expect concrete Korean-flavored Hermes use cases to surface within weeks.
- Next Ralphthon legs. Seoul → SF → Singapore (OpenAI-sponsored) is the current trajectory. Tokyo and a second SF edition are plausible next.
- OmOCon as a recurring institution. Edition 1 in SF (March), edition 2 in Seoul (May), edition 3 TBD. The "builder salon" format is hardening.
- Cross-stack synergy. The same names that sat in the OmOCon room — Hermes (via Nous Research) ↔ Ouroboros (Junghwan Na) ↔ Korean-domain skill libraries — already map cleanly onto a documented three-layer agent stack: Hermes (runtime + messaging gateway) → Ouroboros (spec/quality/cost control) → domain skills (Korean public APIs, real estate, transit, etc.).
7. Why this matters for non-Korean readers
If you're building agents and you're not watching Korea, you're missing:
- A live laboratory for harness design — the people most likely to ship the next abstraction layer for Claude / Codex / Hermes are sitting in this room.
- A working playbook for translating builder energy into global presence without a Bay Area zip code. Hashed + EO + foundation-model partnerships make the path repeatable.
- A culture that treats agent orchestration as the product, not the model. That framing matures faster here than almost anywhere.
The 1,000+ RSVPs for Hermes in Seoul aren't a curiosity. They're the leading indicator.
