Since OpenAI’s ChatGPT launched in November 2022, LLMs have been used across many research fields, but their probabilistic nature means the same prompt can yield different text each run. Variations in hardware, software, and floating‑point arithmetic can also produce subtle output differences, and prompt wording heavily influences results.\n\nThe authors point out that many studies rely on proprietary models whose weights, training data, and architecture are not publicly disclosed, and providers can update models without notice, making exact replication of older work difficult or impossible. To improve transparency, they recommend reporting the exact model and version, justifying any use of proprietary systems over open‑source alternatives, providing the full prompt text, and logging hardware, software, and hyperparameter settings alongside results. They cite emerging guidelines in the behavioral sciences as a positive sign for broader adoption.","keyPoints":["LLM outputs are probabilistic, so identical prompts can produce different results across runs.","Proprietary models hide weights, data, and architecture, hindering exact replication of studies.","Authors advise reporting model version, full prompts, hardware/software specs, and hyperparameters."],"whyItMatters":"Reproducible AI research lets scientists verify claims, compare methods, and build trustworthy systems, which is critical as LLMs become central to many disciplines.","category":{"slug":"research","name":"Research","url":"https://digestai.news/category/research"},"entities":{"companies":["OpenAI"],"models":["ChatGPT"],"people":[]},"firstPublishedAt":"2026-09-22T00:00:00Z","updatedAt":"2026-09-22T00:00:00Z","sourceCount":1,"hasPrimarySource":true,"sources":[{"outlet":"Nature Machine Learning","title":"Reproducibility in the era of large language models","url":"https://nature.com/articles/s43588-026-01061-2","publishedAt":"2026-09-22T00:00:00Z","type":"primary","primary":true,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Opinion: Reproducibility challenges rise with large language models\", 22 September 2026, https://digestai.news/story/opinion-reproducibility-challenges-rise-with-large-language-models","publisher":"Digest AI","title":"Opinion: Reproducibility challenges rise with large language models","datePublished":"2026-09-22T00:00:00Z","url":"https://digestai.news/story/opinion-reproducibility-challenges-rise-with-large-language-models"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
