PhD internship position in AI research focusing on model development for autonomous agentic AI.

Our 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 d
Research areas include: • Post-training & reinforcement learning, off-policy robustness • Self-verification and learning from feedback • Synthetic data generation at scale • Efficient reasoning • World modelling & Env generation
Alongside interesting research, you’ll enjoy a very high GPU-to-researcher ratio.
