Unlocking Lossless Speedups in LLMs via Discrete Diffusion

Subham Sekhar Sahoo, Lingjie Chen, Khiem Pham +14

Large Language Models (LLMs) owe much of their success to next-token prediction (NTP), but their autoregressive (AR) structure requires slow, sequential token generation. To overco…

Translate-R1: Cost-Aware Translation Tool Use via Reinforcement Learning

Pratik Jayarao, Chaitanya Dwivedi, Himanshu Gupta +5

The performance gap across languages in LLMs is well documented, and closing it natively requires pretraining or fine-tuning on corpora that, for most languages, are quite limited.…

Expert Upcycling: Shifting the Compute-Efficient Frontier of Mixture-of-Experts

Chaitanya Dwivedi, Binxuan Huang, Himanshu Gupta +3

Mixture-of-Experts (MoE) has become the dominant architecture for scaling large language models: frontier models routinely decouple total parameters from per-token computation thro…

Code Mixologist : A Practitioner's Guide to Building Code-Mixed LLMs

Himanshu Gupta, Pratik Jayarao, Chaitanya Dwivedi +1

Code-mixing and code-switching (CSW) remain challenging phenomena for large language models (LLMs). Despite recent advances in multilingual modeling, LLMs often struggle in mixed-l…

Explicit Reasoning Makes Better Judges: A Systematic Study on Accuracy, Efficiency, and Robustness

Pratik Jayarao, Himanshu Gupta, Neeraj Varshney +1

As Large Language Models (LLMs) are increasingly adopted as automated judges in benchmarking and reward modeling, ensuring their reliability, efficiency, and robustness has become…
