A new research paper introduces PARSER, a novel long-context agent design that improves accuracy and reduces latency by decoupling document traversal from reasoning. Unlike sequential agents that process chunks one by one, PARSER utilizes a bank of lightweight subagents that read document chunks in parallel. A lead agent then orchestrates iterative scatter-gather rounds, broadcasting queries and aggregating evidence to form deeper follow-up questions. This approach allows a 4B PARSER model to outperform sequential baselines by over 5 points on average and a 9B model to surpass DeepSeek V4-Pro, while also demonstrating robustness to evidence position and order perturbations and cutting inference latency by up to 11x.
