CoF-T2I: Video Models as Pure Visual Reasoners for Text-to-Image Generation
Abstract: Recent video generation models have revealed the emergence of Chain-of-Frame (CoF) reasoning, enabling frame-by-frame visual inference. With this capability, video models have been successfully applied to various visual tasks (e.g., maze solving, visual puzzles). However, their potential to enhance text-to-image (T2I) generation remains largely unexplored due to the absence of a clearly defined visual reasoning starting point and interpretable intermediate states in the T2I generation process. To bridge this gap, we propose CoF-T2I, a model that integrates CoF reasoning into T2I generation via progressive visual refinement, where intermediate frames act as explicit reasoning steps and the final frame is taken as output. To establish such an explicit generation process, we curate CoF-Evol-Instruct, a dataset of CoF trajectories that model the generation process from semantics to aesthetics. To further improve quality and avoid motion artifacts, we enable independent encoding operation for each frame. Experiments show that CoF-T2I significantly outperforms the base video model and achieves competitive performance on challenging benchmarks, reaching 0.86 on GenEval and 7.468 on Imagine-Bench. These results indicate the substantial promise of video models for advancing high-quality text-to-image generation.

CoF-T2I: Video Models as Pure Visual Reasoners for Text-to-Image Generation
Introduction and Motivation
Chain-of-Frame (CoF) reasoning capabilities in large video foundation models have enabled zero-shot visual inference behaviors, manifesting as step-by-step refinement of visual states across consecutive frames. Prior research demonstrates the emergence of sophisticated reasoning in video models applied to tasks such as maze solving and visual puzzles. Despite this, their capacity to enhance text-to-image (T2I) generation remains untapped, primarily due to the absence of explicit visual reasoning steps and interpretable intermediate states in conventional T2I pipelines.
The paper "CoF-T2I: Video Models as Pure Visual Reasoners for Text-to-Image Generation" (2601.10061) proposes a paradigm shift where pretrained video models are repurposed as interpretable, pure visual reasoners for T2I synthesis. The core premise is to leverage the sequential and spatiotemporally coherent generation nature of video models for progressive visual reasoning in image synthesis tasks, decoupling from the prevalent reliance on multimodal feedback or explicit textual Chain-of-Thought (CoT) planning.

Methodology
CoF-T2I Architecture and Generation Process
CoF-T2I reframes T2I generation as a systematic visual reasoning trajectory. Given a text prompt, the model generates a short video sequence where each frame corresponds to a specific reasoning step: a coarse semantic draft, an intermediate refinement, and a final high-fidelity image. Supervision is supplied at all stages, allowing the model to internalize both global semantic correction and local aesthetic improvements.
Technically, CoF-T2I builds on a strong video backbone (Wan2.1-T2V-14B) paired with an independently-applied video VAE. Each frame in the trajectory is encoded and decoded independently to suppress undesirable temporal dependencies and mitigate motion artifacts, thus maximizing spatial fidelity while retaining the causally ordered refinement sequence. The model is optimized via a rectified flow objective, ensuring efficient and accurate capture of the data distribution from noise to high-quality generative states.
Figure 3: CoF-T2I reformulates inference-time reasoning as a visual refinement process; the learning trajectory progresses from semantic to aesthetic improvements, decoding only the final latent for image output.
Dataset and Supervision Design
The CoF-Evol-Instruct dataset is introduced to enable scalable, progressive, and interpretable supervision for CoF reasoning. It comprises 64K three-frame reasoning chains constructed via a quality-aware routing pipeline. Each chain is initialized via diverse T2I backbones and further expanded through a unified editing primitive (UEP), which standardizes semantic and aesthetic transitions.
Anchors of varying initial quality are processed using forward, bidirectional, or backward strategies—semantic correction, aesthetic refinement, or their reverse—ensuring coverage across the compositional spectrum. This dataset avoids the pitfalls of existing T2I or image editing datasets, which lack explicit progression or suffer from inter-frame inconsistency.

Experimental Results
Quantitative Metrics and Ablation
CoF-T2I achieves state-of-the-art performance on both the GenEval and Imagine-Bench benchmarks. On GenEval, it achieves an overall score of 0.86, outperforming strong unified MLLMs (BAGEL-Think 0.82, T2I-R1 0.79) and significantly surpassing traditional image models and raw video backbones. On Imagine-Bench, CoF-T2I attains an overall score of 7.468, marking a substantial gain over the Wan2.1-T2V-14B backbone. The improvement is especially pronounced in semantically complex and compositional subsets (e.g., multi-object, hybridization, attribute-shift).
Ablation studies indicate the critical value of intermediate supervision. A comparison to a target-only fine-tuned baseline (where only the final frame is supervised) shows a delta of 0.05–0.1 in GenEval scores, directly attributable to explicit chain-of-frame training. Removing independent frame encoding (reverting to default continuous VAE) also degrades results, confirming that clear separation of reasoning steps is essential for effective visual correction and detail enrichment.

Qualitative Analysis
Visualization of reasoning chains corroborates the interpretation of CoF-T2I as an explicit visual self-corrector. Intermediate frames systematically resolve semantic errors and incrementally enhance aesthetic realism. Compared to both video backbone and leading reasoning-augmented MLLMs, CoF-T2I generates sharper, more semantically faithful, and visually rich images, particularly where compositional complexity or fine-grained attribute control are required.

Implications and Future Directions
CoF-T2I establishes that video foundation models possess emergent capabilities as inference-time visual reasoners. This approach obviates the need for modality-switching or external reward models, yielding a strictly visual refinement process that is both interpretable and effective. Integrating chain-of-frame supervision directly into the model's training regime leads to competitive, and in many cases superior, performance compared to textual reasoning or typical image generation paradigms.
On the practical side, this methodology provides interpretability: intermediate frames are visual evidence of the model's reasoning states, facilitating inspection and error analysis. Theoretically, chain-of-frame training validates the hypothesis that stepwise supervision structures enable deeper model self-correction and compositional generalization.
Future developments should examine the extension of this paradigm to more complex settings such as text-to-video, open-world simulation, or 3D generation, where sequential visual reasoning holds even greater potential. Combining CoF reasoning with reinforcement learning, as-in Chain-of-Thought in LLMs, is also a compelling research direction for adaptive inference and prompt alignment.
Conclusion
CoF-T2I reassigns the role of video generation models from mere synthesizers to interpretable visual reasoners, advancing the fidelity and semantic adherence of T2I generation. With the introduction of a progressive supervision dataset and a robust training protocol, it delivers both strong empirical results and meaningful intermediate representations. The work highlights the capabilities of chain-structured visual refinement and paves a clear path for future research at the intersection of video foundation models and multimodal reasoning (2601.10061).

Plain-language summary of “CoF-T2I: Video Models as Pure Visual Reasoners for Text-to-Image Generation”
What is this paper about?
This paper shows a new way to make pictures from text using video-making AI. Instead of making a single image all at once, the AI thinks visually in steps, like an artist sketching a rough draft, fixing the important parts, and then polishing the details. The authors call this Chain-of-Frame (CoF) reasoning: the AI creates a short “mini-video” of 3 frames where each frame is a clearer, better version of the last. Only the final frame is shown as the finished picture.
What were the authors trying to do?
The authors asked a simple question: Can a video model, which already knows how to build scenes step-by-step across frames, be used as a pure visual thinker to make better single images from text?
To do that, they set three clear goals:
- Turn text-to-image generation into a visual step-by-step process (draft → refine → final).
- Build training data that shows these steps clearly, from getting the meaning right to polishing the look.
- Make the system produce high-quality images without weird “motion” artifacts that video models sometimes create.
How did they do it? (Methods explained simply)
Think of the model like a careful artist working in three passes:
- Frame 1: a rough draft that gets the main idea and layout.
- Frame 2: a refined version that fixes mistakes (like wrong colors or missing objects).
- Frame 3: the final, high-quality image with clean details and nice lighting.
Key ideas behind the method:
- Using a video model as a “visual reasoner”: Video models are good at improving scenes over time (frame by frame). The authors ask the model to produce just three frames that get better step by step, then they keep only the last frame as the output image.
- A special “camera for data” (VAE) that compresses and decompresses images: Normally, video VAEs compress frames together over time, which can cause tiny wobbles or flickers between frames. To avoid this, the authors compress each frame separately so every step stays crisp and independent.
- A “straight path from noise to image” (rectified flow): When creating images from random noise, the model learns a simple, direct route from noise to the target picture. You can think of it like teaching the model the shortest, smoothest path to reach the final image.
They also created a new dataset to teach the model the right kind of step-by-step thinking:
- CoF-Evol-Instruct: 64,000 three-step “mini-videos” that show how an image should evolve from meaning-first to beauty-polished.
- How they built it: They gathered prompts and images from several text-to-image systems (weak, medium, strong). An AI judge sorted images into three groups: “meaning is wrong,” “meaning is right but looks rough,” and “looks great.” Then, using careful AI editing tools, they expanded each one into a 3-frame sequence:
- Forward: messy → okay → great
- Bidirectional: build both a rougher version and a nicer version around the middle
- Backward: great → simpler → slightly flawed
- This keeps the steps realistic and consistent, like undoing or redoing edits in a smart way.
What did they find, and why does it matter?
Main results (higher is better):
- On GenEval (tests object correctness, counting, colors, positions), CoF-T2I scored 0.86 overall.
- On Imagine-Bench (tests creative, compositional prompts), CoF-T2I scored 7.468 overall.
Why this is important:
- It beats the original video model it was built on by a large margin, showing that “visual step-by-step thinking” really helps.
- It performs competitively with methods that rely on language-based planning, but it does so using only images (no extra text reasoning during generation). That means cleaner, more direct fixes at the pixel level.
- The quality improves from frame 1 to frame 2 to frame 3 in a steady way, proving the step-by-step approach really works as intended.
- Removing the middle steps or not encoding frames independently makes the results worse, showing both choices are necessary.
What could this change in the future?
- Better, more reliable text-to-image tools: Because the model “thinks” visually in steps, it can fix mistakes and sharpen details more consistently.
- Easier debugging and control: The visible middle steps show what went wrong and how it was fixed, making the process more understandable and tunable.
- A new direction for image generation: Instead of relying on language reasoning to guide images, video-style visual reasoning can provide a powerful, purely visual pathway to higher quality.
In short, this paper suggests a simple but strong idea: let video models do what they’re best at—improving visuals frame by frame—to create better single images from text. The three-step “draft → refine → final” process makes images more accurate and beautiful, and could help future systems be both higher quality and easier to control.

- Compute and latency: While only the final frame is decoded in the paper, many applications benefit from decoding intermediates (added cost).
- Model access and licenses: Base video models (e.g., Wan2.1) and editing/assessment LMMs (Qwen family or equivalents) must be available under suitable licenses.
- Safety and governance: Adoption in enterprise/platform contexts requires content safety classifiers, policy alignment, and audit readiness.
- Domain shift: For specialized verticals (e.g., architecture, fashion), targeted fine-tuning and prompt engineering may be necessary to reach production quality.
