Kyutai Moshi vs Remusic

A side-by-side look at pricing, capabilities, pros, cons, and our editorial scores.

	Kyutai Moshi Audio	Remusic Audio
Tagline	Open-source, full-duplex speech-to-speech foundation model with sub-200ms latency	All-in-one AI music studio that bundles song generation, voice cloning, stem splitting, and karaoke tools.
Category	Audio	Audio
Pricing	Free· Free and open source. Models under CC-BY 4.0, code under MIT (Python) / Apache 2.0 (Rust). Self-hosted only — you pay your own compute (24GB+ GPU for PyTorch, or Apple Silicon via MLX).	Freemium· Pro: $20.9/mo · Basic: $7.9/mo · Starter: $4.1/mo
Model	Moshi (7B-class speech-text foundation model) + Mimi neural audio codec, in-house by Kyutai	Remusic V4 Pro (proprietary)
Editorial score	—	7.0 / 10

Pros	Truly full-duplex — handles interruptions, overlap and back-channels rather than rigid turn-taking Sub-200ms practical latency on a single L4 GPU, well below third-party voice APIs Fully open weights (CC-BY 4.0) plus MIT/Apache code — self-host with no per-minute billing Ships with Mimi, a streaming neural audio codec that beats SpeechTokenizer and SemantiCodec Multiple inference backends: PyTorch for research, Rust/Candle for production, MLX for on-device Mac/iPhone Inner-monologue text prediction gives you a transcript alongside the audio stream for free	Bundles song generation, stem splitting, voice cloning, and karaoke in one UI Cheap annual pricing compared with Suno or Udio Daily free credits let you try before subscribing 10,000+ preset voices plus custom clone option Commercial license included on paid tiers
Cons	English-only voices at launch — no multilingual support out of the box Knowledge and reasoning quality trail top text LLMs; it's a 7B-class model, not GPT-4o Voice Requires a 24GB+ GPU for the reference PyTorch build; on-device is only viable via MLX on Apple Silicon No hosted API or SaaS tier — you own the ops, scaling and safety filtering Only two fixed synthetic voices (Moshiko/Moshika); no voice cloning or speaker conditioning in the release	No public API for developers Underlying models and training data are undisclosed Voice-cloning likeness rights are the user's problem Quality of generations is less proven than Suno/Udio
