Research Intern, Together AI

• Currently pursuing a 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

Desirable

• As a Research Intern in the Model Shaping team, you will work on one or more of the following areas:
• Advanced post-training methods across supervised learning, preference optimization, and reinforcement learning
• New techniques and systems for efficient training of neural networks (e.g., distributed training, algorithmic improvements, optimization methods)
• Robust and reliable evaluation of foundation model capabilities
• The Model Shaping team at Together AI works on products and research for tailoring open foundation models to downstream applications
• We build services that allow machine learning developers to choose the best models for their tasks and further improve these models using domain-specific data
• In addition to that, we develop new methods for more efficient model training and evaluation, drawing inspiration from a broad spectrum of ideas across machine learning, natural language processing, and ML systems
• Research and implement novel techniques in one or more of our focus areas
• Design and conduct rigorous experiments to validate hypotheses
• Document findings in scientific publications and blog posts
• Integrate the research results into Together products
• Communicate the plans, progress, and results of projects to the broader team
• Our summer internship program spans over 12 weeks where you’ll have the opportunity to work with industry-leading engineers building a cloud from the ground up and possibly contribute to influential open source projects. Our internship dates are May 18th to August 7th or June 15th to September 4th

• Duration: ~12 weeks (Summer 2026)
