Disclosure: English is my third language and I can’t write for shit in any of them. I used AI to help me write this post. The research, teardown, reverse-engineering, and every technical finding here are entirely mine. The AI helped me say it without making your eyes bleed. If you’d rather argue about prose than NFC antenna multiplexing, this isn’t the post for you. I bought into…
Disclosure: English is my third language and I can’t write for shit in any of them. I used AI to help me write this post.

I run local inference for a side project that processes domain-specific documents, the kind where nuance matters and getting a detail wrong has consequences. My pipeline generates N candidate summaries in parallel, then runs each one through multiple…

Thirty-something years later, I usually can. On the writing: English is my third language and I can’t write for shit in any of them. I use AI to help me write these posts. The research, engineering, teardowns, builds,…
