GEMS: Agent-Native Multimodal Generation with Memory and Skills

Published 30 Mar 2026 in cs.CV | (2603.28088v1)

Abstract: Recent multimodal generation models have achieved remarkable progress on general-purpose generation tasks, yet continue to struggle with complex instructions and specialized downstream tasks. Inspired by the success of advanced agent frameworks such as Claude Code, we propose \textbf{GEMS} (Agent-Native Multimodal \textbf{GE}neration with \textbf{M}emory and \textbf{S}kills), a framework that pushes beyond the inherent limitations of foundational models on both general and downstream tasks. GEMS is built upon three core components. Agent Loop introduces a structured multi-agent framework that iteratively improves generation quality through closed-loop optimization. Agent Memory provides a persistent, trajectory-level memory that hierarchically stores both factual states and compressed experiential summaries, enabling a global view of the optimization process while reducing redundancy. Agent Skill offers an extensible collection of domain-specific expertise with on-demand loading, allowing the system to effectively handle diverse downstream applications. Across five mainstream tasks and four downstream tasks, evaluated on multiple generative backends, GEMS consistently achieves significant performance gains. Most notably, it enables the lightweight 6B model Z-Image-Turbo to surpass the state-of-the-art Nano Banana 2 on GenEval2, demonstrating the effectiveness of agent harness in extending model capabilities beyond their original limits.

Summary

  • The paper introduces GEMS, an agent-native architecture that integrates iterative loops, hierarchical memory, and domain skills to improve multimodal generation performance.
  • The methodology leverages a structured multi-agent system and memory compression to optimize prompt refinement and reduce context redundancy in complex tasks.
  • Empirical results show significant gains, with improvements of +14 to +16 normalized scores and accelerated convergence across both mainstream and domain-specific benchmarks.

Agent-Native Multimodal Generation with Memory and Skills: A Technical Analysis of GEMS

Motivation and Context

Contemporary multimodal generative models have delivered strong performance on general-purpose image synthesis benchmarks. However, these models systematically underperform on complex, multi-faceted instructions and specialized downstream tasks that require compositional reasoning, domain adaptation, or intricate alignment between modalities. Existing inference-time improvement techniques, such as iterative loop refinement and multi-agent systems, are hindered by issues of either context redundancy, limited memory, or low extensibility to non-mainstream or domain-specific settings.

GEMS (Agent-Native Multimodal GEneration with Memory and Skills) is introduced to systematically address these pain points. By fusing agent-based iterative optimization, hierarchical memory, and modular domain skills, GEMS reimagines the text-to-image pipeline as a tightly integrated agentic reasoning and synthesis architecture. Figure 1

System Architecture and Methodology

GEMS is organized around three fundamental modules:

Agent Loop

The Agent Loop is a structured multi-agent system comprising a Planner, Decomposer, Generator, Verifier, and Refiner. The Planner first selects and incorporates relevant domain skills for prompt enhancement. The Decomposer atomizes the prompt into explicit visual criteria, facilitating granular verification. The Generator produces images, which are evaluated by the Verifier using criterion-level feedback. The Refiner synthesizes new prompts by integrating this feedback in conjunction with Agent Memory, thereby closing the optimization loop.

Agent Memory

GEMS introduces a persistent, trajectory-level Agent Memory, which hierarchically organizes the historical record of the entire generation process. Unlike prior works that either ignore long-range dependencies or induce token bloat by simple context accumulation, GEMS archives factual items (prompts, images, feedback) in raw form while selectively compressing verbose reasoning traces into distilled experiential summaries. This approach prunes redundancy without sacrificing useful global context.

Agent Skill

Addressing the limitations of monolithic or hard-coded multi-agent frameworks, GEMS leverages an extensible repository of domain skills, supporting on-demand loading and progressive exposure. Skills are represented as lightweight manifests, incurring negligible token overhead unless triggered. Holistic skill incorporation is achieved without fragmenting the optimization pipeline, and new skills can be registered with minimal user effort.

Empirical Evaluation

Extensive empirical evaluation validates the design of GEMS across five mainstream and four domain-specific benchmarks. Notably, GEMS is assessed on two representative open-source image models—Z-Image-Turbo (6B distilled) and Qwen-Image-2512 (20B)—against competitive inference-time scaling baselines including Maestro and CRAFT.

Key results:

  • On GenEval2 (a compositional, multi-criteria alignment benchmark), GEMS equipped with Z-Image-Turbo achieves a normalized score improvement of +14.22 over baseline, surpassing Nano Banana 2 (SOTA closed-source).
  • On downstream tasks including LongText-Bench, CREA, and ArtiMuse, mean performance gain is +14.03 (normalized), with the greatest margin observed for creative and aesthetic drawing tasks.
  • With Qwen-Image-2512, GEMS achieves average improvements of +16.24 (mainstream) and +7.96 (downstream), confirming architecture-agnostic scalability.

Component Analysis and Ablations

Figure 2: Ablation results on GenEval2 with Z-Image-Turbo: left plot shows additive gains from enabling Agent Loop, Agent Memory, and Agent Skill; right plot details efficacy of different memory configurations.

Dissecting the contributions of individual components, ablation studies on GenEval2 reveal:

  • Agent Loop yields a direct +21.4 improvement over baseline, primarily by enabling selector-driven multi-shot generation and robust failure recovery.
  • Persistent Agent Memory contributes an incremental +9.0 by offering globally consistent refinement signals and eliminating history truncation bias.
  • Agent Skill, when active, enhances scores by +2.1, with skill activations closely matching domain requirements (e.g., Spatial Intelligence on spatial reasoning tasks).

Hierarchical compression within Agent Memory is critical: including raw, unprocessed reasoning traces yields negligible or negative returns due to over-tokenization and noise. Only distilled experience summaries drive further gains. Figure 3

Figure 3: Efficiency-performance trade-off: GEMS (red) attains higher success rates with fewer average generations versus other inference-time scaling methods.

Iteration analysis shows that GEMS, via memory and skills, converges in fewer rounds compared to counterparts, indicating that improvement is not merely from repeated randomization but from genuine directed optimization. Figure 4

Skill Usage and Performance Attribution

Analysis of skill triggering frequency and resultant gains demonstrates that skill selection is interpretable and task-aligned. For instance, Creative Drawing is prevalent in CREA, and Aesthetic Drawing dominates ArtiMuse. The relative contribution of each skill is quantitatively linked with performance increments per task.

Qualitative Assessment

Qualitative comparisons showcase GEMS generating semantically faithful and compositionally sophisticated images across diverse prompts. Notably, GEMS consistently outperforms baselines on alignment to user intent and intricate visual constraints. Figure 6

Implications and Future Prospects

The GEMS framework systematically demonstrates that model-agnostic agent-native reasoning—empowered via persistent, hierarchical memory and modular skills—substantially enhances both general and domain-specific multimodal generation performance. Notably, smaller backbone models can, via agentic harnesses, match or exceed the capabilities of much larger or closed-source counterparts.

Practically, GEMS opens the door to scalable, user-augmented, and easily extensible multimodal AI agents capable of few-shot adaptation, long-term refinement, and expert-guided generation. The strategy of progressive, skill-driven refinement, memory-efficient trajectory storage, and modular extensibility provides a principled template for more advanced, autonomous AI synthesis and content editing systems.

Theoretically, the results call for deeper study of multi-level agentic planning, memory abstraction, and curriculum-based skill injection as means to overcome foundational model limitations without resorting to brute-force parameter scaling.

Conclusion

GEMS introduces a holistic, agent-native architecture that bridges the performance gap on complex and long-tail multimodal generation tasks. By formalizing the process as iterative, memory-driven agentic optimization augmented with on-demand skills, GEMS elevates both compositional image generation and domain transfer for a broad spectrum of settings. The design and findings motivate a shift toward persistent, skill-centric, and memory-efficient agent systems as general-purpose engines for multimodal AI.

Explain it Like I'm 14

What is this paper about?

This paper introduces GEMS, a smart “helper system” that sits on top of image-generating AI models. Its goal is to make those models follow complicated instructions better—especially when prompts have many parts (like object positions, text in the image, style, etc.) or when the task requires special skills (like neat text rendering or artistic layouts).

In short: GEMS turns a regular image model into a small team of helpful “agents” that plan, check, remember, and improve drawings step by step.

What questions were the researchers trying to answer?

The paper asks:

  • How can we help image-generating AI handle complex, multi-step instructions without retraining the model?
  • Can a system that plans, checks, and learns from past attempts (like a team with a shared memory) make images more accurate and high-quality?
  • Can we plug in domain-specific “skills” (like how to render clean text or organize objects in space) only when needed, to do better on specialized tasks?

How does GEMS work?

Think of GEMS as a team with a plan, a checklist, a shared diary, and a toolbox. It runs in a loop: try → check → improve → try again. It has three main parts.

1) Agent Loop: the step-by-step improvement cycle

Analogy: Like a student drafts a drawing, compares it to the instructions, fixes mistakes, and tries again.

  • Planner: Reads your prompt and pulls in any useful skills. It writes a strong starting plan for the image.
  • Decomposer: Breaks your prompt into a simple checklist of “must-haves” (yes/no items), like “Is there a red hat?”, “Is the cat under the table?”
  • Generator: Makes the image from the current plan.
  • Verifier: Checks the image against the checklist and says what’s right or wrong.
  • Refiner: Uses the feedback (and the memory, see below) to improve the plan for the next try.

This loop repeats a few times and stops early if all checklist items are satisfied.

2) Agent Memory: the shared diary (with smart summaries)

Analogy: The team keeps a neat diary of what they tried—saving the important parts and summarizing long thoughts.

  • It stores factual things exactly (the prompts used, the images made, and the yes/no feedback).
  • It compresses long internal “thinking notes” into short “lessons learned” so the next attempt doesn’t get overwhelmed with too much text.
  • This memory helps the system improve steadily instead of repeating the same mistakes.

3) Agent Skill: the on-demand toolbox

Analogy: A big toolbox where you only pull out what you need.

  • GEMS has a library of skills for special tasks (e.g., Creative Drawing, Aesthetic Drawing, Text Rendering, Spatial Intelligence).
  • It only loads the full instructions of a skill when the Planner detects the task needs it. This keeps things fast and focused.
  • Skills are easy to add—just drop in a simple instruction file—and the system can start using it when relevant.

What did they find?

The researchers tested GEMS on many benchmarks that check if models follow instructions well and on specialized tasks. They used two different image models (one small and fast, one larger) to show GEMS works broadly.

Here are the key results:

  • Big overall gains without retraining the models:
    • With a small, efficient model called Z-Image-Turbo (6B parameters), GEMS boosted scores by about +14 points on both mainstream and specialized tasks on average.
    • With a larger open-source model (Qwen-Image-2512), GEMS also improved results a lot: about +16 points on mainstream and +8 points on specialized tasks on average.
  • Beats stronger closed models on a tough benchmark:
    • Using the small Z-Image-Turbo plus GEMS, the system surpassed a leading closed model (Nano Banana 2) on GenEval2, a benchmark known for tough, complex instructions.
  • Efficient and practical:
    • GEMS often finishes in just a few tries (roughly around 3 images on average) thanks to early stopping and good planning.
    • It’s not just “try randomly until it works”—the success rate increases steadily over rounds because GEMS learns from feedback and memory.
  • Why the parts matter:
    • The Agent Loop alone already helps by trying, checking, and refining.
    • Agent Memory adds more improvement by keeping the right history: storing prompts/images/feedback and using short summaries of lessons instead of long, noisy “thinking logs.”
    • Agent Skill gives extra boosts on specialized tasks like text rendering and spatial layouts, where general prompt rewriting often fails.

Why is this important?

  • Works with what you already have: GEMS improves image models at “inference time” (when generating images), meaning you don’t need to retrain or rebuild the whole model.
  • Handles the “long tail” of hard prompts: Complicated instructions and specialty tasks are exactly where most models struggle; GEMS helps them get those right more often.
  • Scalable and flexible: New skills can be added easily, and GEMS only loads what it needs—so it’s both powerful and efficient.
  • Smaller models, bigger results: With smart planning, checking, memory, and skills, even a lightweight model can beat larger, closed systems on complex tasks. That’s good for cost, speed, and accessibility.

Final takeaway

GEMS turns image generation into a guided, learn-as-you-go process. By using a loop to try and improve, a memory to remember what worked, and a toolbox of skills for special needs, it helps AI make images that better match complex instructions. This could make creative apps, design tools, and educational software smarter and more reliable—without needing bigger models or expensive retraining.

Practical Applications

Overview

GEMS is an agent-native framework for multimodal generation that wraps existing image (and potentially other) generative models with three innovations: (1) an iterative, closed-loop multi-agent pipeline (Planner/Decomposer/Generator/Verifier/Refiner), (2) a persistent, hierarchically compressed Agent Memory that preserves factual artifacts and distilled “experiences” across iterations, and (3) an extensible Agent Skill system that loads domain-specific expertise on demand. The framework improves instruction following, spatial reasoning, and specialized tasks (e.g., text rendering, creative/aesthetic drawing) while reducing redundancy and compute via early stopping. Below are practical applications grouped by deployability horizon.

Notes on feasibility and dependencies

  • GEMS is model-agnostic but depends on access to a capable image generator (e.g., Z-Image-Turbo, Qwen-Image) and an MLLM-based Verifier.
  • Benefits rely on decomposition of tasks into evaluable criteria and on well-specified Skill packs for target domains.
  • Iterative loops incur some compute overhead; early stopping and memory compression help but budgets matter.
  • For safety- and regulation-critical domains (e.g., healthcare), expert-curated Skills and human oversight are required.

By deploying GEMS as an inference-time, agentic harness around current T2I systems, organizations can immediately improve instruction adherence, spatial/layout precision, and specialized domain fidelity. Over time, expanding Skill libraries, stronger verifiers, and multi-modal backends can unlock rigorous, auditable, and domain-compliant visual generation at enterprise and societal scale.

  • Closed-loop optimization: An iterative process where feedback from evaluation informs the next action. "iteratively improves generation quality through closed-loop optimization"
  • Compressor: A module that distills verbose reasoning into concise experiential summaries for memory. "are processed by a Compressor Fcomp\mathcal{F}_{comp} to distill them into concise, high-level experiences EiE_i"
  • Context accumulation: Naively appending all prior context in multi-turn processes, often causing redundancy. "unlike simple context accumulation~\cite{jiang2026genagent} or successive single-step updates~\cite{maestro}"
  • Decomposer: The agent that splits a user prompt into atomic, testable criteria for verification. "the Decomposer Fdec\mathcal{F}_{dec} partitions the user's original prompt UU into a set of atomic visual requirements"
  • Distilled model: A compact model derived from a larger one to improve efficiency while retaining performance. "leveraging the lightweight, distilled Z-Image-Turbo"
  • Downstream tasks: Specialized, application-specific tasks beyond general-purpose generation. "including five challenging mainstream benchmarks such as GenEval2 and four specialized downstream tasks spanning diverse domains."
  • Early stopping mechanism: Halting an iterative process once success is detected to save computation. "Due to the early stopping mechanism, GEMS delivers superior performance while maintaining significantly lower overhead."
  • Factual artifacts: Objective, compact records (e.g., prompts, images, feedback) stored verbatim in memory. "Factual artifacts with minimal token footprints, such as the prompt PiP_i, the generated image IiI_i, and the verification feedback ViV_i, serve as reliable and objective data points"
  • Foundational models: Large pretrained generative or LLMs that serve as base capabilities. "pushes beyond the inherent limitations of foundational models on both general and downstream tasks."
  • Generative backends: Underlying generation models used by the agent framework to produce outputs. "Across five mainstream tasks and four downstream tasks, evaluated on multiple generative backends, GEMS consistently achieves significant performance gains."
  • Generator: The component that synthesizes images from the current prompt at each iteration. "The Generator Fgen\mathcal{F}_{gen} is a model-agnostic module responsible for synthesizing the visual output."
  • Hierarchical compression: A memory strategy that stores compact summaries of reasoning while retaining raw facts. "we propose a Hierarchical Compression strategy to manage the historical context."
  • Inference-time scaling: Methods that improve model performance by adding computation and reasoning at inference. "inference-time scaling has emerged as a promising strategy for performance enhancement."
  • Iterative refinement loops: Repeated cycles of generate-evaluate-revise to progressively improve outputs. "have adopted iterative refinement loops to progressively optimize the results."
  • Manifest (lightweight manifest): A minimal index of skills (names and descriptions) that is always loaded. "only the names and descriptions of skills are 'always loaded' as a lightweight manifest."
  • Model-agnostic: Designed to work with different underlying models without modification. "The Generator Fgen\mathcal{F}_{gen} is a model-agnostic module"
  • Multimodal generation: Creating outputs (e.g., images) conditioned on multiple modalities like text and vision. "Multimodal generation has undergone transformative growth in recent years"
  • Multimodal LLM (MLLM): A LLM that processes and reasons over text and images. "The Verifier Fver\mathcal{F}_{ver}, powered by a Multimodal LLM (MLLM)"
  • On-demand loading: Fetching full skill instructions only when a skill is triggered to save tokens. "employing an on-demand loading and progressive exposure mechanism"
  • Parallelism factor: The number of parallel generations or searches run to explore alternatives. "we specifically set the parallelism factor for Search~\cite{ma2025inference} to 5"
  • Planner: The agent that selects relevant skills and crafts the initial enhanced prompt. "The Planner, denoted as Fplan\mathcal{F}_{plan}, serves as the strategic entry point of the system."
  • Progressive exposure mechanism: Gradually revealing detailed skill instructions only when needed. "on-demand loading and progressive exposure mechanism"
  • Refiner: The agent that updates the prompt using feedback and memory to guide the next iteration. "The Refiner Fref\mathcal{F}_{ref} facilitates prompt evolution by closing the feedback loop."
  • Stochasticity: Randomness in the generation process leading to variable outputs across runs. "A primary factor is the inherent stochasticity of the image generation process"
  • Token efficiency: Minimizing the number of tokens used to control costs and context length. "To optimize for both information density and token efficiency, we propose a Hierarchical Compression strategy"
  • Trajectory-level memory: Memory that captures the entire sequence of attempts and reflections across iterations. "provides a persistent, trajectory-level memory"
  • Verifier: The agent that checks generated images against criteria and returns binary feedback. "The Verifier Fver\mathcal{F}_{ver}, powered by a Multimodal LLM (MLLM), assesses the generated image"
