Gemini Nano Banana Pro — the production reference
Gemini Nano Banana Pro — the production reference Today's real second card, drawn by gemini-3-pro-image-preview from the explainer prompt. Zero typos. $0.134.
Local Qwen 35B as HTML — free fallback
Local Qwen 35B as HTML — free fallback Same prompt, Qwen wrote HTML, Chromium screenshotted it. Typo-proof by construction; flatter look. $0.
GLM-Image, poster prompt — iteration 0
GLM-Image, poster prompt — iteration 0 Same explainer prompt through local GLM-Image (50 steps, cfg 1.5). Layout intent right; heavy grain, garbled text. Debug pending.
GLM-Image, simple 6-string poster — iteration 0
GLM-Image, simple 6-string poster — iteration 0 Easy prompt control test. Composition good; same grain; 3/6 strings mangled — points at harness/library drift, not just model limits.
GLM-Image iteration 1 — stable libraries
GLM-Image iteration 1 — stable libraries Same simple 6-string prompt, re-rendered after pinning diffusers 0.39.0 + transformers 5.14.1 (was git dev builds). Testing the library-drift theory for the grain.
GLM-Image iteration 2 — full poster prompt on stable libraries
GLM-Image iteration 2 — full poster prompt on stable libraries The real explainer prompt (40+ exact strings) after the library fix. The decisive dense-text test.
GLM iteration 3 — describe what you changed
GLM iteration 3 — describe what you changed
GLM-Image iteration 3 — same design, headers only (~15 strings)
GLM-Image iteration 3 — same design, headers only (~15 strings) Recreating the Gemini card's exact look with body text stripped to the six headers + title + byline + bottom line. Density-ladder test, seed 42.
GLM-Image iteration 4 — same prompt as iteration 3, seed 7
GLM-Image iteration 4 — same prompt as iteration 3, seed 7 Identical headers-only prompt, different random seed. Shows how much of the string accuracy is sampling luck vs deterministic.
GLM-Image iteration 5 — medium density (~24 strings)
GLM-Image iteration 5 — medium density (~24 strings) Headers plus one short gloss per band and one red WHY IT MATTERS panel. Probes the density ceiling between iteration 3 (clean zone) and the full 40-string prompt (breakdown zone).
GLM-Image iteration 6 — full replica of the Gemini card, seed 42
GLM-Image iteration 6 — full replica of the Gemini card, seed 42 Every string from the real card (icons, red panels, intro, tip, also-strip, role), restructured one-instruction-per-string with letter-perfect emphasis.
GLM-Image iteration 7 — same full-replica prompt, seed 11
GLM-Image iteration 7 — same full-replica prompt, seed 11 Second roll of the dice on the identical prompt, for variance.
