Fine-tuning made it worse, and I still do not know why

What I learned fine-tuning speech models locally · Part 2

I fine-tuned whisper-small on 7.7 hours of real spontaneous speech and made it 2.6 times worse. I had a tidy explanation for it, so I tested the explanation, and the test said I was wrong.

The four stages of a fine-tuning pipeline: data collection, data processing, fine-tuning, testing.

Good speech data is the hard part

Locally fine-tuning Whisper and ASR models with Listenr · Part 1

Whisper is impressive and its vocabulary stopped in 2023. Fine-tuning fixes that, but only if you have high quality data, and getting that is the part nobody wants to do.

LLM generated 3D modeling is the way to go

After hitting walls with FreeCAD, TinkerCAD, and Fusion 360, I discovered that scripting 3D models in OpenSCAD with an LLM produces precise, reusable parts faster than any GUI-based workflow I tried. Two prompts into ChatGPT, I had a working pipe reducer printed and in hand.

Automate Everything: LLMs and Bash Scripts Mean Saved Time

Using LLMs to generate deterministic scripts rather than running real-time AI agents is a more reliable, testable, and repeatable approach to automation. This post explains the strategy, shares real examples from managing this blog, and covers how to keep the output production-ready.

Rethinking Library Dependencies in the GenAI age

Large language models are changing the calculus on when to reach for a third-party library versus generating a lightweight, purpose-built implementation. This post examines the tradeoffs and where a hybrid approach of GenAI-generated code refined by a developer makes the most practical sense.
