Nano Banana Pro vs Flux

Nano Banana Pro vs Flux-2 Pro in NEIRON: face lock vs poster geometry. Not a reprint of GPT Image vs Flux. Table, no VPN.

GPT Image vs Flux is labels and a punch-list. This fork is “person or layout”. Pro holds a face reference. Flux-2 Pro builds a poster, a cover series, and large type without a passport match.

How we compared

One “keep 100%” portrait and one type-heavy poster with no person in the reference. We scored skin vs geometry. GPT Image stayed in the other table.

One prompt

Keep the face 100%, outdoor, rim sunset, 3:4. Second run: sneaker poster, large brand name, 3:2, no face.

Verdict

Hero still with a reference — Nano Banana Pro. Cover series with no person — Flux-2 Pro. A product label is GPT Image vs Flux, not this pair.

Do not burn Pro on every story — version 2 exists for volume. Flux is cheaper to test poster layout.
