About Polybee
We are a Brazilian AI research and engineering company with a global outlook and an open-core philosophy.

Models are part of a larger system. Data, agents, tools, memory, evaluation and compute also determine how AI works.
Polybee researches and builds at these layers. Our mission is to expand who can understand, build, control and benefit from this technology.
Explore our research agendaRooted in Brazil
Language and context shape what systems need to be.
We want Portuguese to be treated as a first-class language in models, data, voice, multimodality and evaluation.
Building from Brazil means developing our own expertise while participating in a global frontier. We combine international collaboration with a real ability to choose.
Research and engineering
Ask questions about models, data, systems and infrastructure, even without a defined product.
Connect inquiry with code, tools, models and infrastructure that can be used in the real world.
Examine behavior, recognize limits and use results to guide new questions.
Open-core sustainability
Sharing knowledge can accelerate an ecosystem. Research also requires resources, infrastructure and time to investigate hard problems.
We open components when doing so expands collective capability, while developing intellectual property, products, licensing, infrastructure and services that sustain the mission. The availability and terms of each technology should be verified when it is released.
