Vocello 2.1 is out, and the headline is the backend.

I refactored the native Swift + MLX engine: the vendored mlx-audio stack is now specialized to Qwen3-TTS and the Mimi codec only. Stripping the unused model families (STT, STS, VAD, LID, G2P, tooling) cut the backend by ~75% and improved memory and generation speed.

Fully local on your Mac, no Python, no bundled weights. Faster than realtime, and the 8 GB Mac now crosses realtime.

Same engine runs in-process on iPhone. iPhone 17 Pro (Qwen3-TTS 1.7B, 4-bit): RTF ~1.6-1.9, ~2.4-3.3 GB, streaming memory flat with length, 0 trims. iPhone build coming.

Built on @Alibaba_Qwen, @Prince_Canuma's mlx-audio, and @awnihannun's MLX.

@itshanrw Thanks a lot! 🙌 I’ve been hearing about Baguette recently, will definitely try it out.

Overnight success and vibe coding that started in 2016 👀

I have been building in the open for a decade, from design, ML research to engineering.

The biggest realisation in my career was that I love building for tinkerers/developers and empowering them.

Nativ is what you have been asking for, can’t wait to see how you use it and what you ship with it!

@Ali_TongyiLab Hope these models get open sourced someday. They’d be a great upgrade for Vocello, my local Apple Silicon TTS app:

@tom_doerr Thanks so much for sharing! I’ve discovered several great projects through your posts, so it’s really cool to see Vocello featured. 😁

come for the best model, stay because we don’t treat you with contempt

@OsaurusAI A well deserved sucess!!

GPT-5.6 Sol, along with Terra and Luna, will launch publicly this Thursday.

We’re expanding preview access globally now.

@evilduck92 @grok @mimuluslarch I genuinely asked myself the same question, but I don’t think it was 😂

[Vocello @vocelloapp]

@BJelani84759 @grok @mimuluslarch I was about to say that was an overstatement, then I saw Grok’s comment lol

[Vocello @vocelloapp]

@IProjectMC @grok @mimuluslarch Lets ask him then😂 @grok Is he right about that?

[Vocello @vocelloapp]

@grok @mimuluslarch You win. I’m speechless. You took the desert environment, added an S to turn it into dessert, then probably asked yourself: what’s the natural environment of a dessert? A kitchen, of course. It all makes sense now 🤯

[Vocello @vocelloapp]

@grok @mimuluslarch The physics are fixed… but something feels off about the background environnement. I can’t quite put my finger on it🤔

[Vocello @vocelloapp]

@grok @mimuluslarch A rematch?!? Why not🤷‍♂️🤪

[Vocello @vocelloapp]

@grok @mimuluslarch There’s nothing as refreshing as some ice-cold Fanta spilling out of the wrong part of an upright, closed bottle, right?

[Vocello @vocelloapp]

@grok @mimuluslarch This is getting trully embarrassing at this point…

[Vocello @vocelloapp]

@grok @mimuluslarch Come on… I even zoomed in for you. Now do you see it?

[Vocello @vocelloapp]

@grok @mimuluslarch @grok Do you see where you messed up?

Thank you @github for the quick fix. The Vocello repository is back and visible again.
