Abstract
Replication package for two studies of code generated by large language models for customs revenue analytics. Contents: harness/ - corpus generator, execution harness, oracle, prompts and the adjudication ledger. prevalence.db holds 1,600 generations across eight tasks (A to H). Tasks A, B and C comprise 600 generations, 495 executing, 264 adjudicated and 102 confirmed faults. prevalence/generations holds the generated programs. robustness/ - three later runs: a multi-realisation direction check over 15,000 program-realisation pairs; a 200-generation replication at zero sampling temperature; and a 200-generation replication under paraphrased prompts. The two replications were scored against the oracle but not adjudicated. Corpus realisations are regenerated deterministically from seeds, so the data files themselves are not shipped. See README.md in the archive. v1.2.0 consolidates the harness, ledger and robustness runs into a single archive.
The results are packaged in the Greenfield Startup Model (GSM), which explains the priority of startups to release the product as quickly as possible, and the need to shorten time-to-market, by speeding up the development through low-precision engineering activities.

StudentSim is a research system for evaluating and improving AI tutoring tools before they are tested with learners. It models how individuals may engage with tutors, giving feedback to improve tutor performance across subjects like chess, writing, and mathematics. The post Simulating student learning for better AI tutoring appeared first on Microsoft Research.
