Latest update (11-10 09:23): Microsoft presents LongCapHarness, a self-improving harness for long-context reasoning

Overview: Microsoft researchers present LongCapHarness, a harness that improves long-context reasoning without synthetic data or post-training. The authors say it raises Llama3-8B by 64.18 points on average across long-context benchmarks and transfers to Qwen2.5-3B.

The authors also say LongCapHarness beats the NExtLong and PolicyLong baselines on the HELMET and RULER benchmarks at less than half their estimated cost. These are the authors' claims, reported by Elvis Saravia on X; the report does not include independent verification.
