Does anyone have working code for fine-tuning PersonaPlex for outgoing calls? I have tried to take the fine tuning LoRA stuff from Kyutai/moshi-finetune and apply it to the personaplex code. Or more accurately,various LLMs have worked on that.

I have something that seems to work in a rough way but only if I turn the lora scaling factor up to 5 and that generally screws it up in other ways.

And then of course when GPT-5.3 Codex looked at it, it said that speaker A and speaker B were switched in the LoRA code. So that is now completely changed and I am going to do another dataset generation and training run.

If anyone is curious it's a bit of a mess but it's on my GitHub under runvnc moshi-finetune and personaplex. It even has a gradio app to generate data and train. But so far no usable results.

Do we have real-time (or close-enough) face-to-face models as well? I'd like to gracefully prove a point to my boss that some of our IAM procedures need to be updated.

Hmm. Would this let me replace my own face in a live videoconferencing session? It seems like it's more of a video chatbot than a v-tuber style overlay.

As a heavy user of MacWhisper (for dictation), I'm looking forward to better speech-to-text models. MacWhisper with Whisper Large v3 Turbo model works fine, but latency adds up quickly, especially if you use online LLMs for post-processing (and it really improves things a lot).

Handy with parakeet v2 is excellent

Had no idea that was what you were asking for. Search for Zoom Face Filter or OBS Face Filter OBS deep fake live etc.

This is cool. It makes me want an unsloth quant though! A 7b local model with tool calling would be genuinely useful, although I understand this is not that. UPDATE: I'd skip this for now - it does not allow any kind of interactive conversation - as I learned after downloading 5G of models - it's a proof of concept that takes a wav file in.

I forked and added tool calling by running another llm in parallel to infer when to call tools it works well for me to toggle lights on and off.
