Here's the story nobody's telling:
Small models stopped being a compromise in 2026.
A 4B model on a laptop handles classification, extraction, cleanup -
the boring work that actually fills your week.
No API keys. No per-token bills. No data leaving your machine.
And that last one matters more than people think.
A court order in 2025 forced OpenAI to keep deleted chats indefinitely.
The EU AI Act started enforcing data rules this month.
Suddenly "send it to the API" isn't the obvious answer anymore - it's a liability.
So the pattern flipped:
~70% of routine AI tasks can run locally, for free, instantly.
The remaining 20-30% - deep reasoning, long context - that's what frontier APIs are for.
This is the same lesson my trading systems taught me:
The tools that survive are the small ones.
The ones that do one thing, do it fast, and never leak.
My CSV tool runs fully in the browser for the same reason.
Your data never leaves your machine. It doesn't need to.
What's the last thing you sent to an API
that should have stayed on your laptop?
