We introduce Carl — Zhang Haotian, an Interior Design student at HBU-UCLAN, trained end-to-end on the problem of putting humans into rooms they actually want to stand in. The model exhibits strong performance on plan drawing, material matching, and holding coffee while critiquing someone else's thesis.

A future-space explorer connecting design, brand, and technology.

Capability radar / live scan

Where the model is strongest.

A soft map of Carl's design operating system, calibrated across spatial thinking, AI workflows, visual output, and narrative strategy.

§ 04 — Peer review / Very legitimate

Rigorously evaluated by three (3) anonymous reviewers.

Conflicts of interest: extensive. Disclosures: none.

Reviewer #1 · Accept

"The work demonstrates that a 21-year-old can, in fact, hold an opinion about a door. Recommend acceptance."

Prof. L. Thesis advisor · reluctantly impressed
Reviewer #2 · Weak accept

"I'm his mom. He cleaned his room once. The spatial sensitivity checks out."

Mrs. Zhang Conflict of interest: biological
Reviewer #3 · Accept w/ revisions

"Good kerning on the title slide. Recommend minor revisions: fewer black t-shirts."
