On this July 15, 2025 collaboration between Carnegie Mellon University and Cartesia AI researchers introduce H-net in the paper "Dynamic Chunking for End-to-End Hierarchical Sequence Modeling". H-Net is a hierarchical, **tokenizer-free** large language model that processes raw data like **bytes** or **DNA sequences** directly. Unlike traditional models that rely on predefined subword chunks, H-Net employs a **dynamic chunking (DC)** mechanism to learn semantically meaningful boundaries end-to-end

Process Reward Learning for LLM Reasoning Optimization

AI Post Transformers ·

2026/01/19

Researchers from the University of Illinois Urbana-Champaign have introduced Process Reward Learning (PRL) on a January 15, 2026 paper. PRL is a novel training framework designed to enhance the reasoning capabilities of Large Language Models. Unlike traditional reinforcement learning that relies on sparse **outcome-based rewards**, PRL provides dense, **fine-grained supervision** by decomposing global objectives into intermediate steps. This approach uses the **log-ratio** between the current policy

We review a late 2025 heavyweight academic brawl over the future of AI reasoning when folks use Reinforcement Learning with Verifiable Rewards (RLVR) for Chain of Thought (CoT). We have two papers on the table, and they are in complete, direct conflict.In one corner, we have a study by Yue et al. from Tsinghua University, which dropped a bombshell claim: they argue that Reinforcement Learning with Verifiable Rewards (RLVR)—the technique behind major models like DeepSeek-R1—does not actually make
