Udio is the consumer-facing brand of Uncharted Labs, a generative music startup founded in 2023 by David Ding, Andrew Sanchez, Yunpeng Li, Conor Durkan and Charlie Nash, all former members of Google DeepMind who had worked on the Lyria, AudioLM and MusicLM research lines. The company emerged from stealth in April 2024 with a $10M seed round led by Andreessen Horowitz and backed by celebrity investors including will.i.am, Common and Mike Shinoda, plus Tao Capital and Instagram co-founder Mike Krieger. Udio v1 launched in April 2024 and quickly drew comparisons to Suno; v1.5 followed in July 2024 with longer outputs, stem extraction, key/tempo control and higher-quality vocals. Like Suno, Udio is named in a June 2024 RIAA lawsuit alleging large-scale training on copyrighted commercial recordings.
Visit Udio (Uncharted Labs) →Udio v1.5 is a proprietary text-to-music model that takes free-form prompts (genre, mood, lyrics, structure tags such as [verse], [chorus], [outro]) and outputs full-band stereo music at 44.1 kHz with synthesised vocals. The team has not published a technical report but the company describes a 'multi-stage neural network' that combines a Transformer text encoder with a generative audio backbone over neural audio codec tokens, in line with their published DeepMind heritage on Lyria and AudioLM. v1.5 introduced stem extraction (vocals/drums/instrumental), an inpaint/extend interface that lets users edit specific bars, key and tempo manipulation, and stereo output. Lyric inputs are supported in many languages with controllable pronunciation. The system is offered exclusively as a hosted SaaS product with a free credit tier and paid Pro/Premium plans; no weights are released and the training corpus is not disclosed.

Not disclosed. Udio states they trained on a 'wide range of music', and the RIAA lawsuit alleges large-scale ingestion of copyrighted commercial recordings; Udio disputes this and argues fair use.
License: Proprietary hosted SaaS. Pro/Premium plans grant commercial use rights to generated audio (subject to ongoing legal uncertainty around training data).
Known limitations
