PosterCopilot: Toward Layout Reasoning and Controllable Editing for Professional Graphic Design (2512.04082v1)
Abstract: Graphic design forms the cornerstone of modern visual communication, serving as a vital medium for promoting cultural and commercial events. Recent advances have explored automating this process using Large Multimodal Models (LMMs), yet existing methods often produce geometrically inaccurate layouts and lack the iterative, layer-specific editing required in professional workflows. To address these limitations, we present PosterCopilot, a framework that advances layout reasoning and controllable editing for professional graphic design. Specifically, we introduce a progressive three-stage training strategy that equips LMMs with geometric understanding and aesthetic reasoning for layout design, consisting of Perturbed Supervised Fine-Tuning, Reinforcement Learning for Visual-Reality Alignment, and Reinforcement Learning from Aesthetic Feedback. Furthermore, we develop a complete workflow that couples the trained LMM-based design model with generative models, enabling layer-controllable, iterative editing for precise element refinement while maintaining global visual consistency. Extensive experiments demonstrate that PosterCopilot achieves geometrically accurate and aesthetically superior layouts, offering unprecedented controllability for professional iterative design.

PosterCopilot: Toward Layout Reasoning and Controllable Editing for Professional Graphic Design
Introduction
PosterCopilot advances the automatic generation and controllable editing of professional multi-layer graphic design, addressing persistent issues in current LMM-driven design frameworks. Existing models for graphic layout generation frequently exhibit geometric misalignments and visual discord when handling complex, asset-rich scenarios, and lack iterative, layer-specific editability—a core requirement in professional design workflows. PosterCopilot introduces a progressive three-stage training paradigm and integrates a generative agent, establishing a decoupled workflow for layout planning and multi-round, high-fidelity editing. This results in substantial improvements in geometric precision, aesthetic quality, and interactive control.

Core Technical Contributions
PosterCopilot's methodological contribution is two-fold: (1) a progressive, three-stage alignment pipeline for Large Multimodal Models (LMMs) focused on continuous geometric reasoning and explicit aesthetic alignment, and (2) a cohesive design+edit workflow integrating LMM-based layout planning with generative models capable of iterative, fine-grained, lossless editing.
Perturbed Supervised Fine-Tuning (PSFT): Traditional LMMs quantize continuous spatial coordinates into discrete tokens, disrupting the underlying optimization geometry and resulting in spatial artifacts in generated layouts. PosterCopilot replaces this with PSFT, where ground-truth coordinates are augmented via Gaussian perturbations, and the model is trained to match a distribution rather than a single point target.
Figure 2: Perturbed Supervised Fine-Tuning (PSFT)
This reformulation enables the model to learn over a smoother, more continuous parameter space, as substantiated by visualizing the local structure tensor. Neighborhood averaging of perturbed samples regularizes the learning process and alleviates the collapse of signal observed in text-based regression.

Reinforcement Learning for Visual-Reality Alignment (RL-VRA): To resolve SFT's lack of visual feedback, RL-VRA introduces a geometry-aware reward incorporating DIoU for spatial coherence, aspect ratio and size preservation for element fidelity, and output parseability. Policy updates use Group Relative Policy Optimization (GRPO) to efficiently optimize in high-dimensional, discrete action spaces.
Reinforcement Learning from Aesthetic Feedback (RLAF): While RL-VRA enforces geometric correctness, RLAF leverages an LMM-based reward model trained to assess human-like aesthetics, extending optimization beyond ground-truth layouts into regions of high visual appeal as judged by learned reward models. This multi-stage RL protocol effectively reconciles objective correctness with subjective aesthetic quality.

PosterCopilot Workflow: Layout Reasoning and Controllable Editing
PosterCopilot's architecture decouples layout reasoning (via an LMM-based design master) from asset synthesis and editing (via a generative agent). In cases of insufficient assets, the agent completes the asset pool with style-congruent generation. During inference and iterative design refinement, PosterCopilot precisely targets single layers for edit operations, guaranteeing both high edit fidelity and global composition integrity.

Poster Generation from Fully-provided and Incomplete Assets: When all assets are specified, the model produces visually coherent and compositionally sound results, preserving asset fidelity. For incomplete assets, PosterCopilot synthesizes compatible layers, maintaining stylistic and thematic consistency.

Multi-round Fine-grained Editing and Thematic Reframing: PosterCopilot handles multi-step edits—precisely altering material, pose, or even theme—while maintaining the integrity of untouched layers and the global structure, capabilities which diffusion-based methods fail to provide.

Poster Reframing: PosterCopilot can re-align and regenerate layouts for new canvas specifications without manual intervention, automatically adapting layouts and preserving compositional harmony.

Dataset Curation and Pipeline
Current multi-layer poster datasets suffer from over-segmentation and semantic fragmentation, undermining robust model supervision. PosterCopilot introduces a 160K-instance, 2.6M-layer dataset, employing an OCR-driven, fine-granularity bounding box pipeline for meaningful layer reduction and rational grouping. This refined annotation protocol addresses critical gaps in data quality for realistic layer-level design modeling.

Experimental Results
Quantitative and Human-Centric Evaluation
PosterCopilot is benchmarked against commercial (Nano-Banana, Microsoft Designer) and academic (LaDeCo, CreatiPoster) and large-scale reasoning baselines (Gemini, Qwen-VL). Metrics include both human-centric (Layout Rationality, Style Consistency, Asset Preservation, Visual Appeal, Instruction Following) and geometric (IoU, ARD, IOPR) indicators.
User studies reveal an average win rate above 74% across all competitors, with PosterCopilot particularly excelling in layout rationality, asset preservation, and visual appeal. GPT-5 evaluations corroborate these findings, with the model decisively outperforming baselines on holistic quality and nearly all dimensions except text legibility, where PosterCopilot’s commitment to faithful text inclusion contrasts with text omission in certain competitors.

Figure 14: Results of GPT-5 evaluation.
Ablation studies substantiate the necessity of each training stage. RL-VRA phase delivers significant boosts in layout metric accuracy over PSFT, with RLAF further improving aesthetic metrics at the expense of negligible IoU reduction, consistent with optimization toward subjective rather than ground-truth metrics.

Qualitative Comparison and Editing Superiority
Qualitative evaluation against Nano-Banana in layer-wise editing substantiates the higher edit fidelity and global consistency of PosterCopilot across multiple scenarios. While Nano-Banana exhibits rapid distortion under iterative edits, PosterCopilot maintains stable compositions with precise single-layer changes.

Theoretical Implications and Future Developments
PosterCopilot's multi-stage fine-tuning and RL protocol addresses the core limitation of token-based geometric representation in LMMs, offering a generalizable path for continuous parameter regression with LMMs across vision-language tasks. Integration of high-level aesthetic rewards bridges the divide between objective correctness and subjective quality in model alignment. The dataset construction methodology sets a precedent for structured, multi-layer visual modeling in design-centric AI.
Future directions include the development of reward models specifically tuned for poster aesthetics, leveraging user-in-the-loop or preference-driven RL objectives for even tighter alignment, and exploring advanced layer-blend modes simulating expert graphic design software.
Conclusion
PosterCopilot introduces a paradigm shift in automated graphic design systems by decoupling layout reasoning from asset synthesis and enabling controllable, iterative layer-level editing. Its progressive fine-tuning and RL framework, combined with a large, high-quality dataset, yields strong subjective and objective performance gains. PosterCopilot establishes a new state-of-the-art in controllable, professional, multi-layer design automation and paves the way for more semantically aligned and editable AI-driven design workflows.

Explaining “PosterCopilot: Toward Layout Reasoning and Controllable Editing for Professional Graphic Design”
1. What is this paper about?
This paper introduces PosterCopilot, an AI system that helps make professional-looking posters. It doesn’t just create a first draft—it can also carefully edit and improve designs, piece by piece, like a skilled graphic designer. The big idea is to teach AI how to arrange images, text, and shapes on a canvas in smart, good-looking ways, and then let it make precise changes without messing up the whole picture.
2. What questions does the paper try to answer?
In simple terms, the researchers ask:
- How can we get AI to place design elements (like photos and words) neatly and correctly on a poster?
- How can the AI understand both geometry (where things go and how big they are) and aesthetics (what looks good)?
- How can the AI make careful edits—like changing just one object or one line of text—without changing everything else?
- Can this approach beat current tools and produce designs that look professional?
3. How does PosterCopilot work? (Simple explanation)
Think of making a poster like arranging furniture in a room: you need to decide where the couch goes, how big the table should be, and what looks balanced and nice. PosterCopilot learns to do this in three training stages and then works with a “teammate” that can generate or edit images when needed.
Here’s what the three training stages do (imagine training a player with different coaches):
- Stage 1: Perturbed Supervised Fine-Tuning (PSFT)
- Analogy: Practice with slight variations to learn the “feel” of space.
- Instead of learning exact coordinates as fixed points, the AI practices with small, controlled “wobbles” around the correct positions. This helps it understand continuous space better—like learning to place a picture frame on a wall even if you start slightly off.
- Stage 2: Reinforcement Learning for Visual-Reality Alignment (RL-VRA)
- Analogy: A geometry coach checks the poster after it’s “hung,” correcting crooked frames, stretched images, or misplaced boxes.
- The AI gets rewards for accurate placement, keeping sizes and proportions correct, and outputting results in the right format. It learns to fix geometric mistakes (for example, not squashing a photo or drifting away from the intended position).
- Stage 3: Reinforcement Learning from Aesthetic Feedback (RLAF)
- Analogy: An art teacher gives feedback on what looks attractive and balanced.
- The AI explores more creative layouts and gets rewarded for designs that look good overall, even if they differ a bit from the original “answer.”
After training, PosterCopilot connects to a generative “agent” (another AI helper):
- If you don’t have all the assets (like a background image), the agent can create missing parts in the same style.
- It supports layer-specific editing: imagine each element on the poster sits on its own transparent sheet. You can change one sheet (like swapping a lollipop for an ice cream) without disturbing the others.
- It can do multiple rounds of edits, responding to precise instructions, while keeping the overall layout consistent.
4. What did they find, and why does it matter?
The researchers tested PosterCopilot against other tools, including popular commercial platforms and academic methods. They used both human designers and an AI judge to compare results.
Key findings:
- PosterCopilot won most head-to-head comparisons, with an average win rate above 74% in user studies.
- It especially excelled at:
- Keeping user-provided elements intact (not removing or warping them).
- Making layouts that look organized, balanced, and professional.
- Following instructions while maintaining visual style and consistency.
- Technical studies showed that:
- The second stage (RL-VRA) greatly improved geometric accuracy—boxes were placed and sized more correctly.
- The third stage (RLAF) boosted the overall look and appeal of posters.
- It also supports powerful editing:
- Single-layer edits without distortion (like changing a character’s pose or material).
- Theme switching (e.g., turning a “lollipop sale” poster into an “ice cream promotion” while keeping the same layout).
- Reframing to different canvas sizes while maintaining harmony.
Why it matters:
- Designers often need many rounds of precise edits. PosterCopilot supports that workflow while protecting the original assets.
- It helps bridge the gap between “what the computer generates” and “what looks good to people,” combining logic (geometry) with taste (aesthetics).
5. What’s the impact and what comes next?
Implications:
- PosterCopilot could act like a design assistant: it drafts, arranges, fixes, and improves your poster step by step.
- It makes AI-powered design more practical for real-world use—especially when lots of small edits are needed.
- It contributes a large, well-organized dataset of layered posters (160,000 posters with 2.6 million layers), which can help future research.
Limitations and future work:
- The “art teacher” reward is not tailored specifically to posters yet; a poster-specific aesthetic model could improve results further.
- Blend modes (how layers visually mix) are standard—exploring more creative blending could add polish.
Overall, PosterCopilot pushes AI design toward professional standards: better layout reasoning, careful control over edits, and results that look good—not just “correct.”
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a concise list of unresolved issues, missing analyses, and actionable open questions for future work.
- Coordinate representation: The model still decodes continuous layout coordinates via discrete text tokens; no comparison to numeric heads or hybrid decoders (e.g., continuous regression modules or keypoint heads) that could eliminate token-induced geometric artifacts.
- PSFT design choices: The perturbation scheme (noise distribution, magnitude σ, per-dimension scaling, number of samples n) lacks principled selection and sensitivity analysis across asset densities and canvas sizes; theoretical grounding beyond the structure-tensor intuition is missing.
- Geometry validation: The “geometric instability” claim for text-based spaces is not quantitatively validated beyond a visualization; no controlled experiments isolating tokenization vs. decoding strategies to causally attribute errors.
- RL-VRA reliance on ground truth: The geometric reward depends on ground-truth boxes, limiting applicability to labeled data; how to extend alignment to unlabeled or in-the-wild assets via self-supervised visual constraints (overlap, alignment, symmetry, whitespace, grid adherence)?
- Reward shaping and stability: No ablation on KL coefficient β, GRPO group size K, clipping, or reward weights (λsize, λAR); training stability, sample efficiency, and variance across seeds remain unreported.
- Aesthetic reward validity: RLAF uses a generic aesthetic judge (VisualQuality-R1) not tailored to posters; needs a poster-specific, culturally robust, and bias-audited preference model, with tests for reward hacking and generalization across styles and regions.
- Human preference data: Absent collection of designer preference data to train or calibrate the aesthetic reward; open question on incorporating expert pairwise preferences or rubric-based scoring for typography, balance, and hierarchy.
- Typography modeling: Text is rasterized and evaluated coarsely; no explicit modeling of font selection, hierarchy, kerning, tracking, line breaks, text wrap, or grid-based typesetting; addressing text legibility (a known weakness) requires typography-aware modules and metrics.
- Multilingual and non-Latin scripts: No evaluation on scripts with complex shaping (Arabic, Devanagari), CJK fonts, right-to-left layouts, and accessibility considerations (contrast, font size).
- Beyond axis-aligned boxes: The system is limited to rectangular bounding boxes with no rotation, skew, masks, or vector shapes; support for Bezier curves, clipping paths, and rotated text/objects is not explored.
- Layer semantics and compositing: Layering is treated as z-order only; there is no controllable blend mode learning (the paper lists “standard blend modes” as a limitation), shadow/lighting, transparency, or advanced compositing controls common in professional tools.
- Dataset construction quality: OCR-based layer merging may introduce grouping errors; there is no quantitative audit of segmentation correctness, per-category quality, genre coverage, or annotation noise, nor a bias analysis (e.g., language, market, style distributions).
- Dataset availability and licensing: The paper claims a large multi-layer dataset but does not specify release terms, licenses, or usage restrictions; reproducibility and community benchmarking depend on public availability.
- Editing evaluation: No quantitative metrics for edit locality (how strictly edits are confined to target layers), preservation (unchanged layers), semantic fidelity, and layout stability across multi-round edits; no user paper focused on iterative editing quality.
- Style consistency measurement: Asset synthesis and theme switching claim stylistic consistency but lack quantitative metrics (e.g., palette distance, CLIP-style embeddings, LPIPS/SSIM on reference-guided style) and controlled failure analyses.
- Constraint-aware design: The system does not explicitly support brand guidelines, modular grids, safe margins/bleeds, CMYK color constraints, or print specifications; how to encode and satisfy hard constraints during layout reasoning remains open.
- Robustness and scaling: No stress tests for extreme scenarios (50+ assets, tiny fonts, heavy occlusion, extreme aspect ratios); performance degradation and failure modes under high complexity are not characterized.
- Latency and resource profile: Inference time per design and per edit round, GPU/CPU memory footprint, and feasibility for interactive, real-time workflows are not reported; on-device or low-resource deployment is unaddressed.
- Generalization to other mediums: Applicability to magazines, brochures, social-media banners, UI screens, and animated layouts is unexplored; transfer learning or domain adaptation strategies are not studied.
- Instruction parsing reliability: The pipeline assumes accurate conversion of natural language requirements to structured constraints; robustness to underspecified, conflicting, or ambiguous instructions remains uncertain.
- Evaluation methodology: Reliance on proprietary GPT-5 for scoring (with omissions for instruction following and element preservation) reduces reproducibility; inter-rater reliability, statistical significance tests, and blinded protocols for human studies are not detailed.
- Comparative quantitative benchmarks: IoU/IOPR/ARD are used only for ablations, not for cross-method comparisons; a standardized public benchmark with agreed-upon quantitative and preference metrics is missing.
- Human-in-the-loop learning: The system does not learn from real designers’ iterative corrections; integrating online preference learning or correction-driven RL for continual improvement is an open direction.
- Failure handling and reliability: No metrics on JSON formatting failures, invalid outputs, or recovery strategies; robustness of the format reward and parser under distribution shifts is unclear.
- Backbone dependence: Results depend on Qwen backbones and VisualQuality-R1; portability to other LMMs/T2I models, and sensitivity to backbone choice, are not examined.
