--- So.3d ----, 2026 WL 785016 Footnotes “Generative AI[—i.e., generative artificial intelligence—]are deep-learning models that compile data to generate statistically probable outputs when prompted.... Generative AI can create original images, analyze documents, and draft briefs based on written prompts. Often, these programs rely on large language models. The datasets utilized by generative AI large language models can included billions of parameters making it virtually impossible to determine how a program came to a specific result.... [G]enerative AI can hallucinate or create inaccurate answers that sound convincing.” Fla. Bar Ethics Op. 24-1, at 1-2 (Jan. 19, 2024) (citations and internal quotation marks omitted).
