The Turbo Research team investigates how to make post-training and reinforcement learning for large language models efficient, scalable, and reliable. Our work sits at the intersection of RL algorithms, inference systems, and large-scale experimentation, where the cost and structure of inference dominate overall training efficiency and shape what learning algorithms are practical.
As a research intern, you will study RL and post-training methods whose performance and scalability are tightly coupled to inference behavior, co-designing algorithms and systems rather than treating them independently. Projects aim to unlock new regimes of experimentation—larger models, longer rollouts, and more complex evaluations—by rethinking how inference, scheduling, and training interact.
Pursuing a PhD or MS in Computer Science, EE, or a related field (exceptional undergraduates considered)
Have research experience in one or more of:
RL or post-training for large models (e.g., RLHF, RLAIF, GRPO, preference optimization)
ML systems (inference engines, runtimes, distributed systems)
Large-scale empirical ML research or evaluation
Are comfortable with empirical research by designing controlled experiments, while interpreting noisy results and drawing principled conclusions
Can work across abstraction layers:
Strong Python skills for experimentation
Willingness to modify inference or training systems (experience with C++, CUDA, or similar is a plus)
Intern projects are tailored to your background and interests, and may include:
Inference-Aware RL & Post-Training
Designing RL or preference-optimization objectives that explicitly account for inference cost and structure (e.g., speculative decoding, partial rollouts, controllable sampling).
Studying how inference-time approximations affect learning dynamics in GRPO-, RLHF-, RLAIF-, or DPO-style methods.
Analyzing bias, variance, and stability trade-offs introduced by accelerated inference within RL loops.
RL-Centric Inference Systems
Developing inference mechanisms that support deterministic, reproducible RL rollouts at scale.
Exploring batching, scheduling, and memory-management strategies optimized for RL and evaluation workloads rather than pure serving.
Investigating how KV-cache policies, sampling controls, or runtime abstractions influence learning efficiency.
Scaling Laws & Cost–Quality Trade-offs
Empirically characterizing how reward improvement and generalization scale with rollout cost, latency, and throughput.
Quantifying when systems-level optimizations change algorithmic behavior rather than only reducing runtime.
Identifying regimes where inference efficiency unlocks qualitatively new learning capabilities.
Evaluation & Measurement
Designing rigorous benchmarks and diagnostics for post-training and RL efficiency.
Studying failure modes in long-horizon training and how system constraints shape outcomes.
Our fall internship program spans over 12 to 16 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 September 14th to December 18th.
