Show HN: Tesoro.help – rogue AI helpdesk for my kid's high school

https://tesoro.help/

My kid just started high school. The way they communicate information is absolutely insane. So I built a web scraper + MCP to aggregate it all, then layered on a snarky chatbot with a PG-13 Dave Chappelle personality.The number of communication channels are just insane: - email - Google Docs - Canvas - PDFs - School Messenger - the official school website - 5 different other websites that...

Show HN: Local Motion – Use Cursor Agents and Chat with a Local LLM

https://github.com/mattmireles/local-motion

Using a local LLM for coding agents is complicated, so I built a Cursor + VS Code plugin that makes it easy.It automatically profiles your machine, picks a model that works for your machine, then runs a local server, sets up a Cloudflare Quick Tunnel and walks you through connecting it to Cursor.In the end, you work like you normally do in Cursor and just choose "Local Motion" as your model in...

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

Show HN: Gist Discover – TikTok for ArXiv Summaries

https://gist.is/discover

Dunno about you, but I cannot keep up with the volume of AI research. Reading one paper properly takes 30–60 minutes, and it's hard to know which are even worth it.I built Gist, an AI summarizer for ADHD brains. Each paper is a clean slide deck with four layers you move through:1. the Gist – the whole idea 1-2 sentences 2. Logic – breakdown of the argument + evidence in discrete ideas 3....

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.

Show HN: Magenta Real-Time Music Generation Locally on iPhone, Without the GPU

https://github.com/mattmireles/magenta-realtime-2-iphone

Last Thursday, Deepmind released Magenta Realtime 2 , an open source music generation model. They said it could run on Mac, but not iPhone.As a v̵i̵b̵e̵ ̵c̵o̵d̵i̵n̵g̵ ̵a̵d̵d̵i̵c̵t̵ agentic AI maxxi and person who has melted iPhones before (link at bottom), I took that as a personal challenge and made it my weekend project.On Saturday, I got it to run for 10min straight on an iPhone 12 Pro from...

Re:Show HN: Gemma 4 Multimodal Fine-Tuner for Apple Silicon on Wednesday April 08, 2026 @12:46AM (#47685377)
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.
Re:Show HN: Gemma 4 Multimodal Fine-Tuner for Apple Silicon on Wednesday April 08, 2026 @12:43AM (#47685353)
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).
