About

MusicGPT is an AI-powered music creation platform that lets you generate full original music, beats, instrumentals, lyrics, vocals, sound effects and soundscapes simply by typing a description of what you want, letting the AI produce professional quality tracks across genres in seconds.

It includes a simple prompt box for song creation, support for text-to-speech with thousands of realistic voices, an AI voice changer, AI stem splitter, audio enhancements and the ability to isolate vocals or instruments. MusicGPT runs on proprietary AI audio technology and integrates via a flexible API for developers to power apps or projects, while users can stream and download unlimited music they create.

About

StepAudio 3 is StepFun’s next-generation audio model family, built to understand, generate, and interact through voice, sound, and music. The lineup includes StepAudio 3 Realtime for natural full-duplex conversation, StepAudio 3 ASR for speech recognition, StepAudio 3 TTS for speech synthesis, StepAudio 3 Gen for general-purpose audio generation, and StepAudio 3 Music for long-form music creation. Realtime is designed around a continuous listen-converse-think-act loop, understanding not only words but also hesitation, laughter, emotion, pauses, backchannels, and interruptions. It can think while speaking, reason through harder questions without breaking conversational flow, and use tools to complete tasks once it understands the user’s intent. StepAudio 3 Gen unifies zero-shot TTS, voice design, vocal generation, sound effects, music, and mixed audio generation within one framework, while StepAudio 3 Music supports text-controlled songs, instrumentals, vocal arrangement, and more.
