序章PROLOGUE · 世界, “THE WORLD”
Seven islands. 350 models.
One worktable.
Sekai is an illustrated archipelago where AI models live by what they do best: coders in the Cedar Forest, deep reasoners on the High Peaks, long-memory models out in Snow Country.
Find one that fits the job, then take it to the Worktable, a desk that runs in your browser and talks to OpenRouter, OpenAI, Anthropic, Ollama and more with your own key.
第一話EPISODE 01 · THE ARCHIPELAGO
Every island
has a specialty.
Seven provinces, sorted by strength: writing, code, reasoning, memory, vision, speed and making things. Pick a landscape and meet who lives there.
EVERYDAY INTELLIGENCE
Blossom Valley
Cherry trees shelter a village of familiar voices. Come here to write, think, and begin something new.
第二話EPISODE 02 · THE WORKTABLE
A desk that runs
in your browser.
Chat, draft, put two models head to head, make images. Your keys and drafts stay on this device; export them when you move.
Three ways in.
One desk.
Talk it through.
Chat with any model your provider serves, and switch models whenever the job changes.
Make pictures and sound.
Images, stories, sound and video, through the connected providers that support them.
Keep it on one desk.
Projects, head-to-head comparisons and saved workflows live together, not in twelve tabs.
第三話EPISODE 03 · THE ROSTER
The whole cast,
on one page.
Filter by the job, sort by context window, and open any model for its inputs, limits and province.
Select a model name for a closer look.
A curated snapshot, not a live feed. Catalog updated . Provider availability may change.

第四話EPISODE 04 · FIRST RUN
Three steps to
your first reply.
- 一
Pick a model.
Search the roster or walk the islands until one fits the job in front of you.
- 二
Bring a key.
Paste a key from OpenRouter or another provider, or point the Worktable at Ollama on this computer.
- 三
Start talking.
Threads, drafts and images save in this browser. Export a backup whenever you like.
番外編EXTRA · FIELD NOTES
Before you
set sail.
Straight answers. No account needed to look around.
What is Sekai?
A Japanese-inspired world for discovering AI models and a worktable for using them. The seven provinces organize models by their strengths. The landscapes and villages are fictional; the model catalog and connected tools are functional.
Do I need to connect a provider?
You can explore, search, compare models, and organize projects without connecting anything. Generating responses or media requires a supported provider connection and any credits that provider charges. Connections are managed in your worktable.
Where does my work live?
Your worktable, drafts, and saved viewpoints are stored in this browser. Media is saved locally when browser storage is available. Use the worktable export tools to keep a backup or move your projects to another device. There is no automatic account sync.
Can I use it on my phone?
Yes. The website and worktable adapt to smaller screens. Pinch to zoom in the world and use its touch controls to walk. You can lower render quality in World settings or explore the model directory without entering the 3D world.
Can I reduce the animation?
Sekai respects your device’s reduced-motion setting. You can also pause the website’s decorative motion using the control at the bottom of this page. The world’s graphics settings are available while exploring.
