My life mission is to make Korea proud.
I turn every moment into an inspiring story to reach that goal.
Money doesn't inspire for long, but a great story does.
> Quit Intel 2yrs ago, burned the boats.
> Love fast iterating and building.
> All my life, I cared about what others thought. Now I'm learning not to.
> Not fluent in English, but made 20+ close US friends in 3 months.
> Love crashing through any kind of barrier.

Building AI-native game for kids: "how can we define fun?", "core-fun-loop?"
There is the kind that fills you and returns you to where you were: a snack, a rest, the near miss at a slot machine that teases a craving it invented. It feels good and changes nothing.
And there is the other kind, the kind that asks effort of you and leaves you slightly larger than before. The level you died at ten times and cleared on the eleventh. The crooked fort you built with your own hands and are prouder of than any perfect one you could have bought.
The difference is simple. Pride lives not in the thing but in the effort of making it. Deep fun is the reward stamped on growth, and its size is proportional to the resistance you crossed.
Remove the resistance and you remove the reward.
spent 8 months as a solo-founder, I started my startup journey with 2 co-founders.
what I found is solo-founder doesn't work for me.
To build a product, we need to do tons of things. Some of them could be automatically operated by AI agents, but still human need to think for making a better plan and reviewing results.
As a single human, it's hard to think all the things.
solo-founders, how do you manage your time? how do you set the priority and make plans?
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

To ICML 2026 authors,
I’m organizing a networking event for researchers and builders interested in AI and education.
If you’re working in this space and would like to share your research, ideas, or products, I’d love for you to join us.

Why do people love vibe coding?
It’s basically similar to a slot machine in a casino.
Instant output. Near misses.
“One more prompt will make it work.”
Please stop chasing dopamine.
Do engineering. Do coding.
Everyone’s talking about the Fable.
I don’t think the future is about using AI
to reproduce what already exists.
thinking a lot about what an AI-native game looks like, and how we can make it both fun and educational.
interested in AI, games, or learning, I’d love to chat.
I don’t like to be an average person.
I don’t wanna just flow along with the river called “the world".
I’m building a nAI-native game for kids.
Not for the everyone
Not on Roblox or Minecraft.
I’m thinking deeply about the core play instincts of humans, especially kids, and how AI can amplify them.
Not in a dopamine-driven way.
I wanna understand what makes children curious, immersed, creative, persistent, and alive while they play.
That’s the kind of world I want to build.
Kids are growing up with AI before they fully develop their own thinking skills.
That changes everything.
Many parents already feel this anxiety:
“How do I help my child prepare for the AI era?”
But kids do not want AI lessons.
They want to play.
That’s why I think AI-native games may become one of the most important learning environments of the next decade.
Not games that simply use AI.
Games where kids naturally learn:
how to ask better questions
break problems into smaller tasks
judge whether AI outputs actually make sense
solve problems with AI
But there’s one important condition:
The game has to be genuinely fun.
If it feels educational first, kids will leave immediately.
One of the best examples of this philosophy is LEGO.
Kids simply enjoy building, while parents instinctively feel something valuable is happening underneath.
That’s the kind of experience we want to build with Sunny Street.
Have you ever imagine about "AI-native game for kids"?
- Cozy farm simulation with AI NPC
- Problem solving with AI (drought, supply shortage)
Want to chat with someone who interests in this field.

Made cutscene video for my game by using GPT5.5 + Image2 + Seedance2 + Elevenlabs.
1. Generate story board (#1~#7)
2. Get images for each episodes
3. Use seedance for making videos (#1~#2, #2~#3, ..)
