Role summary

Together AI is seeking Research Interns for its Inference Research team for Summer 2027. This role focuses on building efficient, scalable, and reliable serving systems for large foundation models, contributing to open and transparent AI. Interns will work on distributed inference, compiler-aware optimization, and novel inference strategies, co-designing software, algorithms, and models to reduce cost and latency. Responsibilities include designing and conducting experiments, communicating findings, and documenting results. The program runs 12-14 weeks with competitive compensation. This is a remote internship opportunity.

About The Role

The Inference Research team is dedicated to building the next generation of efficient, scalable, and reliable serving systems for large foundation models, directly contributing to the mission of advancing open and transparent AI. Our work operates at the critical intersection of cutting-edge model architectures, high-performance systems engineering, and deep hardware optimization. We focus on co-designing software, algorithms, and models to significantly lower the cost and latency of modern AI systems.

As a research intern, you will dive into the complexities of distributed inference, compiler-aware optimization, and novel inference-time computation strategies (such as speculative decoding and phase-aware execution). You will be tasked with co-designing and implementing cross-layer optimizations across models, systems, and hardware, with a focus on areas like KV cache design and large-scale serving architectures.

Projects aim to unlock unprecedented performance and scale for foundation models, enabling faster serving, larger model deployment (e.g., Mixture-of-Experts), and robust, reproducible evaluation under realistic serving workloads.

Responsibilities

Design and conduct rigorous experiments to validate hypotheses

Communicate the plans, progress, and results of projects to the broader team

Document findings in scientific publications and blog posts

Requirements

Currently pursuing a final year of Bachelor's, Master's, or Ph.D. degree in Computer Science, Electrical Engineering, or a related field

Strong knowledge of Machine Learning and Deep Learning fundamentals

Experience with deep learning frameworks (PyTorch, JAX, etc.)

Strong programming skills in Python

Familiarity with Transformer architectures and recent developments in foundation models

Preferred Qualifications

Prior research experience in foundation models, efficient machine learning, or ML systems.

Publications at leading conferences in machine learning or systems (i.e., MLSys, ICLR).

Experience with CUDA programming (for kernel development)

Understanding of model optimization techniques and hardware acceleration approaches

Contributions to open-source machine learning projects
