Role summary

Together AI is seeking a Research Intern for their Frontier Agents team to work on cutting-edge AI systems capable of complex, multi-step tasks. This role focuses on agentic AI, alignment, reliability, and scalability, operating at the intersection of agent capabilities, HCI, and infrastructure. Interns will research and implement novel techniques, design experiments, and contribute to scientific publications. Requirements include a Ph.D. pursuit in a related field, strong ML/DL fundamentals, experience with deep learning frameworks (PyTorch, JAX), understanding of LLMs, and Python programming skills. The internship program runs 12-14 weeks, with competitive compensation.

About the Role

The Agents team investigates how to build, align, and scale frontier AI systems that can tackle complex, multi-step tasks and workflows across text and speech, with a particular focus on agentic and scientific domains. Our work sits at the intersection of agent capabilities, human-computer interaction, and infrastructure—from designing post-training methods for agentic behavior to developing evaluation frameworks for open-ended tasks where traditional metrics fall short.

As a research intern, you will work on problems at the frontier of agentic AI, where challenges in alignment, reliability, and scalability are deeply intertwined. Projects may involve developing new training recipes for self-learning and long-horizon reasoning, curating datasets for non-deterministic scientific and agentic tasks, studying failure modes in agentic behavior, or building infrastructure that enables agent operations at scale. You'll operate in a space where algorithmic innovation, dataset and interaction design, and systems work come together to push the boundaries of what AI agents can reliably accomplish.
