Can a free model on a 2017 CPU replace a paid API for reading receipts?

Qwen2.5-7B, 8.8 s per receipt. The 3B model stalled at 0.50, and I stopped tuning rather than fit the test.

One-person AI studio · Bali
Websites and WhatsApp automations for small businesses in Bali.
I'm Adit. I build the parts that keep a small business running: the booking page, the WhatsApp replies, the invoices. Every project below says plainly whether it's live, tested or still a prototype.

01 · What I build
Three things, sized for a one-owner business
For the owner who runs the business from a phone full of WhatsApp chats.
A one-page site with WhatsApp booking
Price list, photos, the area you cover, and a button that opens WhatsApp with the booking already typed. Example: legacybarberhousecall.com.
A WhatsApp receptionist
Answers at 9pm, offers slots that are really open on your calendar, books the visit and reminds the customer the day before. It never quotes a price you didn't give it.
Admin automations
Invoices, follow-ups, receipts and a morning report, connected to the Gmail, Google Sheets or Notion you already use.

03 · Lab
Measured experiments
For the engineers reading this. The numbers are real, including the ones that went against my first guess.
Does an AI need to see a chart, or is a caption enough?
0%→46.7%chart Qs
Captions alone answered none of the chart questions, even when they found the right chart more often.
ExperimentWhich search setup works best for legal research?
88%recall@1 · 6 ms
Plain keyword search (BM25) won. The reranker was about 475× slower.
ExperimentA research desk that refuses any claim it can't cite.
A critic agent rejects uncited answers. The eval runs in CI and fails the build below its threshold.
ExperimentSearch over my own skills and notes.
Retrieval and answer quality are scored separately, so a good answer can't hide a bad search.
ExperimentA voice assistant on my PC with Claude as the brain.
Talks back, opens apps, searches, remembers notes. Smoke-tested live on 18 Oct; 22 test files. A personal tool.

05 · How I work
Four rules every build follows
A
Nothing goes out without a yes
Drafting is automatic. Sending, posting, paying and deploying always wait for a human to approve.
B
A second AI checks every code change
Before Claude edits code, Codex reviews the change and can block it. If the reviewer is down, edits stop.
C
Tested before it talks to a customer
The receptionist had to pass 63 of 63 checks first, including offering only real open slots and never quoting a price.
D
Decisions are written down
Every stack choice is logged with the reason and the tradeoff, so you can see why it was built that way.
