About StepAudio 3
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.

MiniMax Music 3.0
MiniMax Music 3.0 is a music-generation API for creating songs from a description, lyrics, or reference audio. Developers use the prompt parameter to define style, mood, instrumentation, vocal character, and production direction, while the lyrics parameter supplies vocal content. Its upgraded semantic model improves creative-intent understanding and reduces drift in AI-generated music. Higher sound quality produces clearer mixes and supports specific instruments and playing techniques such as slides and legato. A new vocal engine delivers more natural synthesis with control over melody, pronunciation, breathing, and layered harmonies. Teams can first call the Lyrics Generation API to write full lyrics with sections such as Verse, Chorus, and Bridge, then send them to the Music Generation API, or skip that step and generate a song directly with lyrics optimization. Music 3.0 also supports instrumental-only creation.

MusicGPT
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 provides tools to edit audio, upload and transform existing files, extract stems, remix tracks or create sound effects and samples with hyper-realistic quality, and explore a royalty-free music library for discovery and inspiration. 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.

Dessa
Dessa is Block's speech-to-speech artificial intelligence model for conversational voice research and applications. It takes audio input and produces audio output directly, without converting speech into text as an intermediate step. Trained from scratch on human conversation rather than text, the model supports full-duplex interaction, listening and speaking at the same time, and runs locally on a MacBook Pro with an M4 Max chip or better. It captures conversational cues such as emotion, sarcasm, laughter, pauses, and turn-taking that can be lost in text-based pipelines. Dessa is intended for AI safety researchers and developers studying voice-model behavior, privacy, and real-time interaction. It is a speech model for research and development, not a general-purpose business application or hosted voice-agent platform.

Seed-Music
Seed-Music is a unified framework for high-quality and controlled music generation and editing, capable of producing vocal and instrumental works from multimodal inputs such as lyrics, style descriptions, sheet music, audio references, or voice prompts, and of supporting post-production editing of existing tracks by allowing direct modification of melodies, timbres, lyrics, or instruments. It combines autoregressive language modeling with diffusion approaches and a three-stage pipeline comprising representation learning (which encodes raw audio into intermediate representations, including audio tokens, symbolic music tokens, and vocoder latents), generation (which transforms these multimodal inputs into music representations), and rendering (which converts those representations into high-fidelity audio). The system supports lead-sheet to song conversion, singing synthesis, voice conversion, audio continuation, style transfer, and fine-grained control over music structure.
