Character Engine
Persona modelling that holds a consistent voice, motive and boundary across thousands of turns — not just the first ten.
We believe the next great storyisn't written for you.It's lived with you — one message at a time.
WHO WE ARE
OSHIMOS is an AI-native character lab. We build the models, the memory and the craft that let a character hold a conversation worth coming back to — then ship it to millions of people, in their own language, on their own terms.
Registered in Singapore. Building for the world.
Six systems we own end to end. No middleware between us and the experience.
Persona modelling that holds a consistent voice, motive and boundary across thousands of turns — not just the first ten.
A character remembers what mattered and lets go of what did not. Continuity is a retrieval problem, and we treat it like one.
A multi-model gateway that picks the right model for each turn, balancing latency, cost and craft in real time.
Portraits, scenes and voice generated in-context, so the character you imagine is the character you see and hear.
Offline evals before release, online experiments after. Every change to a character is measured against the conversation it produces.
Layered moderation, age assurance and region-aware policy, built into the pipeline rather than bolted on at the edge.
OUR PRODUCT
AI Character Chat & Roleplay
Thousands of characters, written by a community and brought to life by our engine. From personality to conversation style, anyone can create an AI that feels truly alive.

HOW WE WORK
One team owns a surface from model to pixel. No handoffs, no translation loss.
Every release is an experiment with a hypothesis attached and a number that settles it.
Architecture decisions, evals and post-mortems are documents anyone inside can read.
CAREERS
We are hiring across model research, inference infrastructure, product engineering and trust & safety. Remote-friendly, Singapore-registered, English and Mandarin both work.
