UniCo: A Data Framework for Better Causal Reasoning

ChenhaoTan · x · 2026-07-18

Introduces UniCo, a data generation framework designed to enhance the causal reasoning capabilities of large language models.

• The authors claim that training around a "causal center" helps models develop causal thinking that better aligns with the real world, thereby improving faithfulness and consistent reasoning.
• After performing SFT with 66.6K entries of UniCo data, they observed:
• A 22.9% improvement across 18 types of causal QA tasks;
• An 8.1% gain on 7 existing causal tasks compared to current data generation frameworks;
• A 20.2% boost in faithfulness for real-world generalized reasoning.
• The paper notes that tests on Qwen3 and Olmo-3-Instruct yielded significant improvements for both.
