Founder/CEO at TalkTastic.com

Previously, I co-founded SpeakerText (speakertext.com), a interactive/social layer on top of online video, and Humanoid (gethumanoid.com), a crowdsourced virtual labor service that uses machine learning to track worker reputation on Mechanical Turk and ensure quality.

In previous lives, I fought forest fires in Montana & Alaska for the US Forest Service, worked as a freelance news reporter for the NY Times, and drove a 911 ambulance in Harlem and the South Bronx.

Ha, I built a version of the same thing as a Cursor plugin. Check it out:

https://open-vsx.org/extension/Transcendence/gist-discover https://gist.is/discover

We literally posted our Show HNs within minutes of each other: https://news.ycombinator.com/item?id=48768342

Great minds think alike.

Dr. Alex Mathiasen, PhD wants to build a pause button for human biology – so that you can live forever. All he needs is enough GPUs to simulate quantum physics.

yeah, it came out after I stared on my project last year. Only issue is that you can't fine-tune it on Apple Silicon.

depends on the model!

If you run a smaller whisper-distil variant AND you optimize the decoder to run on Apple Neural Engine, you can get latency down to ~300ms without any backend infra.

The issue is that the smaller models tend to suck, which is why the fine-tuning is valuable.

My hypothesis is that you can distill a giant model like Gemini into a tiny distilled whisper model.

but it depends on the machina you are running, which is why local AI is a PITA.

Look inside here: https://github.com/mattmireles/gemma-tuner-multimodal/tree/m...

Here’s the trick: use Gemini Pro deep research to create “Advanced Hacker’s Field Guide for X” where X is the problem that you are trying to solve. Ask for all the known issues, common bugs, unintuitive patterns, etc. Get very detailed if you want.

Then feed that to Claude / Codex / Cursor. Basically, create a cheat sheet for your AI agents.

This will unlock a whole new level of capability.

More data -> better, faster on-device models

The actual plan was to distill Gemini 2.5 Pro into the best on-device voice dictation model.

Pretty sure it would have worked. Alas.

re: Whisper v3 -- how is this possible? Whisper has a 30s context window. You have to chunk it.

Great minds think alike!

Also, I had a huge head start, as I spent a month or two working on this in September 2025, shelved it and dusted it back off this weekend.

Haven’t tried yet. That’s on the do list. But good suggestion.

you are welcome! It was a fun side quest

Memory usage increases quadratically with sequence length. Therefore, using shorter sequences during fine-tuning can prevent memory explosions. On my 64GB RAM machine, I'm limited to input sequences of about 2,000 tokens, considering my average output for the fine-tuning task is around 1,000 tokens (~3k tokens total).
