We promote a mindset of openness, learning, and collaboration, where everyone has something to contribute.
About the Team
The Models team builds the foundational models that power our cutting-edge agentic technology.
We focus on training techniques to optimize model capabilities specifically for agent applications.
This allows us to achieve the best performance at a given inference cost.
Our work spans the development of Large Language Models (LLMs) and Vision‑Language Models (VLMs), enabling agents to perceive, understand, and act within complex environments.
We are deeply involved in enhancing these models through training methods with a focus on improved instruction following, tool use, and interaction with dynamic environments via large‑scale reinforcement learning and reward modeling.
We operate at the intersection of research and product, translating cutting‑edge research into practical solutions that drive the next generation of AI.
We are looking for bright, motivated individuals to join our ranks and shape the future of superintelligent AI.
