  "focus": "Compression, verifiable reasoning and what a model can still do with less.",
  "bio": "Sisong Bei studies what a language model keeps when its context or its reasoning is rewritten into a smaller, more checkable form. The questions run through most of the collaboration's compression and reasoning papers: which facts survive a learned symbolic rewrite, how relational structure holds up at a realised token budget, how an edit in one document ripples through the documents linked to it, and whether a reasoning trace can be linted the way code is.\n\nSisong is first author on Telegraph Reasoning, Context Compression Is Not One Thing, What Survives Learned Symbolic Compression?, Evaluating Relational Context Compression at Realized Token Budgets, RippleKB, Measuring Answer Accuracy and Trace Verifiability, and the paper on why additive process rewards wash out under group normalisation. Sisong is also a co-author on the error-accumulation trilogy, Telegraph English and the conversation-analytics papers.",
