Two undergrads built an AI speech model to rival NotebookLM

April 22, 2025: Undergrads Create AI Model to Rival NotebookLM - Two undergrads from Nari Labs developed Dia, an AI speech model that rivals Google's NotebookLM. Despite minimal AI expertise, they created Dia using 1.6 billion parameters to produce customizable podcast-style voices and nonverbal cues. Available on Hugging Face and GitHub, Dia runs on modern PCs and includes voice cloning capabilities.

However, Dia lacks safeguards against misuse, which raises concerns about disinformation. Despite legal uncertainties over training data sources, Nari plans to expand Dia into a synthetic voice platform with social features and support for other languages.
