There are no lossless transformations of natural-language text

Simon Willison’s Weblog 2 months ago 42

Sophie Alpert argues that there are no lossless transformations of natural-language text, meaning every rewrite changes meaning and can lose information if the rephraser lacks a detailed representation of the original author’s intent. She emphasizes that any AI-assisted writing must be backed by the engineer’s own ideas and sentences and that replying to reviewer questions with an “AI wrote it” explanation is not acceptable. As a result, engineers are expected to review and own their entire documents rather than treat AI edits as interchangeable with their original thoughts.

How ONESTRUCTION built the Ishigaki-IDS foundation model with AWS GenAIIC

Amazon Web Services 2 months ago 20

ONESTRUCTION and AWS built Ishigaki-IDS, a construction/BIM domain-specialized foundation model trained to generate and validate IDS files using a three-stage approach (CPT, SFT, RLVR) and an IDS-Audit-Tool reward signal under GENIAC Phase 3 with AWS GenAIIC advisory. In their IDS-Bench evaluation, Ishigaki-IDS scored close to 100 percent on XML structural compliance and IDS structural compliance, and above 80 percent on IDS content consistency, while general frontier models scored roughly under 25 percent on IDS structural compliance and near 0 percent on IDS content consistency. The outcome changes by making IDS authoring and review more accurate and usable for construction practitioners—including non-specialists—especially in a data-scarce domain where general models struggle with IDS structure and content.
