Gradium just released phonon-31m-en, a lightweight English text-to-speech model built on Pocket TTS and Kyutai's Mimi codec. Weighing just 64.5 MB in 8-bit quantization, it streams natural 24 kHz speech entirely on-device across laptops, smartphones, and web browsers under the Apache 2.0 license. Why it matters: offline, zero-latency voice agents just became dirt cheap to deploy anywhere.
Mirelo and Kyutai just open-sourced MuScriptor, a new audio-to-MIDI model that handles full, complex music mixes. Instead of tripping over overlapping instruments like older single-track tools, it transcribes entire songs into separate MIDI tracks for vocals, drums, bass, and keys all at once. It's basically a dream shortcut for producers and learners looking to rip clean tracks straight into their DAW.
Kyutai just open-sourced Pocket TTS, a lightweight 100M-parameter text-to-speech model built to run entirely on CPUs without GPUs. It clocks in at roughly 6x real-time on a MacBook Air M4 with a 200ms time-to-first-audio latency, bringing voice cloning and infinite text streaming straight to consumer hardware.
Kyutai just introduced Hibiki, a simultaneous speech-to-speech translation model currently handling French to English. It delivers real-time voice and text translations while keeping the speaker's original timbre and pacing naturally. Evaluations show it rivals professional interpreters in naturalness and accuracy.
French research lab Kyutai just unveiled Moshi, an open-source conversational voice AI boasting an end-to-end latency of only 200 milliseconds. Built from scratch in six months, it can listen and talk at the same time and run directly on a laptop without an internet connection.
