Role summary

Together AI is seeking a Research Intern for their Frontier Speculative Decoding team for Summer 2027. This role focuses on building and improving algorithms for faster large language model generation without altering outputs. Interns will research new drafter architectures, knowledge distillation techniques, and adaptive drafters. Responsibilities include training and fine-tuning models on GPU clusters, testing ideas against realistic serving workloads, and communicating findings. The ideal candidate is pursuing a Master's or Ph.D. in a related field with strong ML/DL knowledge and experience in distributed training frameworks. Prior research in speculative decoding or efficient ML is preferred.

About the Role

The Speculative Decoding team at Together AI builds the draft models and algorithms that let large language models generate faster without changing their outputs. Our speculators run in production on frontier open models such as DeepSeek, Kimi and GLM. Our work sits at the intersection of model training, inference algorithms and serving systems, and we co-design all three to lower the cost and latency of generation.

As a research intern, you will dive into open questions in speculative decoding: new drafter architectures and verification schemes, knowledge distillation and training recipes that align draft and target models, and drafters that adapt as traffic shifts. You will train and fine-tune draft models at scale on dedicated GPU clusters, and test your ideas against realistic serving workloads, including long-context and agentic traffic.

Projects aim to answer important research questions in speculative decoding, enabling faster generation on frontier models, drafters that keep pace with changing workloads, and robust, reproducible evaluation under real traffic.

Past Research

Speculative decoding research by Together researchers, interns and academic collaborators includes:

Speculative Speculative Decoding (ICLR 2026)

When RL Meets Adaptive Speculative Training: A Unified Training-Serving System (ICML 2026)

Beat the Long Tail: Distribution-Aware Speculative Decoding for RL Training (MLSys 2026)

Responsibilities

Research and prototype new efficient speculative decoding algorithms and draft model architectures

Train, fine-tune and distill draft models, and design rigorous experiments to validate hypotheses.

Implement optimized version for serving engines to show efficacy in real world workloads

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

Share findings through technical write-ups and blog posts, and help bring successful ideas into production

Requirements

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

Strong knowledge of Machine Learning and Deep Learning fundamentals

Hands-on experience training or fine-tuning large models with distributed training frameworks (e.g., Megatron-LM, FSDP)

Familiarity with modern model architectures, such as Mixture-of-Experts and hybrid attention

Preferred Qualifications

Prior research experience in speculative decoding, efficient inference, or efficient machine learning

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

Experience with knowledge distillation, post-training, or reinforcement learning

Familiarity with LLM serving engines (e.g., vLLM, SGLang, TensorRT-LLM)

Contributions to open-source machine learning projects
