Introduction
Why We Tested ERNIE Image
ERNIE Image became one of the most discussed open-weight releases after Baidu's ERNIE team introduced it publicly (April 2026 release context, with broad 2026 adoption momentum). We tested it because claims around text rendering, structured generation, and multilingual accuracy directly affect real creative workflows where most image models fail.
This review focuses on EEAT-style practical questions: does ERNIE Image actually follow complex instructions, preserve layout logic in multi-element prompts, and keep text readable enough for poster, manga, bilingual packaging, and product marketing use cases?
Architecture
Architecture Deep Dive
ERNIE Image is centered on an 8B single-stream DiT with a companion 3B Prompt Enhancer. Instead of dual-stream separation, text and visual tokens are processed in a unified sequence, improving cross-modal alignment in structured prompts.
Unified sequence modeling
Stronger global coherence for prompts containing many objects, attributes, and explicit constraints.
Text-first rendering reliability
Designed to keep in-image text legible under richer composition and typography requests.
Structured panel understanding
Performs better on multi-panel and storyboard-like layouts where continuity matters.
Production deployment path
A practical local baseline is around 24GB VRAM, plus ecosystem tools for varied workflows.
In short: the architecture targets instruction fidelity and layout/text control first, then style. That priority is why ERNIE Image often feels more dependable for text-heavy commercial design tasks.
Methodology
ERNIE Image Benchmark Methodology
We interpret benchmark outcomes through a production lens: text fidelity, instruction following, multilingual robustness, and structured composition reliability. Scores are read as directional signals, then validated against visible outputs and prompt stress tests.

Results
Real Test Results
Category 01 - Posters & Text Rendering
5.0/5Prompt class: text-heavy poster layout
"Summer Music Festival poster - bold serif title at top, lineup names in white on dark teal background, minimal art deco border"
Review Note
ERNIE Image consistently rendered headline text legibly with stronger letter spacing control than most open-weight peers. Layout intent was preserved without severe text corruption in our poster-format checks.
Category 02 - Film-like Photography
4.9/5Prompt class: cinematic street still
"Tokyo alley at golden hour, warm amber backlight, cyclist passing in blur, subtle film grain, shot at eye level"
Review Note
This category showed ERNIE Image's film-like bias: light direction and grain feel were visually coherent, though ultra-photoreal skin and micro-texture can still be softer than FLUX-class outputs.
Category 03 - Manga / Storyboard
4.8/5Prompt class: multi-panel narrative consistency
"4-panel manga: panel 1 girl runs through rainy street, panel 2 finds a glowing door, panel 3 steps through, panel 4 emerges in a sunlit meadow - clean line art, expressive faces"
Review Note
Multi-panel continuity remained strong: character identity, outfit, and narrative flow held across frames better than typical single-shot-first models.
Category 04 - Multilingual + Multi-panel
4.8/5Prompt class: bilingual labels + structured composition
"Product label design: 'Matcha Latte' in clean sans-serif at top, '抹茶拿铁' in elegant brush-style Chinese below, sage green palette, minimal Japanese aesthetic"
Review Note
Bilingual text handling was notably stable. Chinese and English labels remained cleaner than most open-weight alternatives in the same complexity range.

Feature Deep Dive
5 Official Showcase Categories
Open ERNIE Image Create →We scored visible outputs across the five official categories: Posters/Text, Film-like, Manga/Storyboard, Multilingual Text, and Multi-panel structured generation.
Interpretation: ERNIE Image is strongest when prompts require explicit structure and in-frame readable text.
| Category | Observed Quality | Notes |
|---|---|---|
| Posters / Text | Excellent | Legibility and placement stability are standout strengths. |
| Film-like | Very good | Organic mood is strong; hyperreal edge can vary by prompt. |
Structured Prompt Compliance
Read Prompt Guide →ERNIE Image follows multi-element instructions with above-average consistency for an open-weight model, especially when the prompt specifies composition, text payload, and panel relationships.
"4-panel manga with fixed protagonist identity, readable title text, bilingual product sign"
This is where ERNIE Image differentiates: the model is less likely to ignore constraints when prompts include explicit structure requirements.
Published Benchmark Snapshot
| Benchmark | Score / Rank |
|---|---|
| GENEval | 0.8856 (#1 open-weight) |
| LongTextBench | 0.9733 (#2 overall) |
| OneIG-ZH / OneIG-EN | 0.8351 (#2) / 0.8197 (#3) |
Prompt Patterns That Work Best
High-performing prompts usually include explicit text payload, composition constraints, and style directives in one compact instruction:
"Poster with readable headline + subtitle, centered hierarchy, dark teal art deco border"
"4-panel storyboard, same protagonist outfit and face, emotional progression frame by frame"
"Bilingual product label: English + Chinese, exact text lock, minimal Japanese aesthetic"

Conclusion
Final Verdict: ERNIE Image is best-in-class for text rendering + structured generation.
Our 2026 verdict gives ERNIE Image an overall 4.5/5. It leads open-weight peers where many teams struggle most: readable in-image text, strict prompt adherence, multilingual labeling, and multi-panel structure continuity.
If your workflow depends on posters, bilingual assets, manga/storyboards, and structured visual instructions, ERNIE Image should be your first benchmark. For pure photoreal-only goals, FLUX-class models can still be worth parallel testing.
