Be part of us in Atlanta on April tenth and discover the panorama of safety workforce. We are going to discover the imaginative and prescient, advantages, and use circumstances of AI for safety groups. Request an invitation right here.
Stability AI is continuous to push ahead its imaginative and prescient for generative AI with the Steady Audio 2.0 audio mannequin in the present day.
Stability AI is probably finest identified for its text-to-image Steady Diffusion fashions, however that’s solely one among many fashions the corporate has been engaged on. Steady Audio had its preliminary launch in Sept. 2023, introducing the flexibility for customers to generate brief audio clips with a easy textual content immediate. With Steady Audio 2.0, customers can generate high-quality audio tracks of as much as 3 minutes, double the 90 seconds the preliminary Steady Audio launch enabled.
Along with supporting text-to-audio, Steady Audio 2.0 may also help audio-to-audio technology, the place customers add a pattern they wish to use as a immediate.

The AI Impression Tour – Atlanta
Persevering with our tour, we’re headed to Atlanta for the AI Impression Tour cease on April tenth. This unique, invite-only occasion, in partnership with Microsoft, will function discussions on how generative AI is reworking the safety workforce.

That is an development from the prior Steady Audio launch that would solely create brief loops or fragments quite than full-length songs.
Trying on the machine studying (ML) science behind Steady Audio 2.0, the mannequin nonetheless depends on what is called a latent diffusion mannequin (LDM). Evans defined that for the reason that Steady Audio 1.1 beta launch replace that got here out in December Steady Audio has had a transformer spine, making it what he known as a “diffusion transformer” mannequin.
“We additionally elevated the quantity of information compression we apply to the audio information throughout coaching, permitting us to scale the mannequin outputs to a few minutes and past whereas sustaining cheap inference occasions,” Evans mentioned.
Remodeling audio samples with textual content prompts
