Large vision models (LVMs) can automate and improve visual tasks such as defect detection, medical diagnosis, and environmental monitoring.
We benchmarked three object detection models: YOLOv8n, DETR, and GPT-4o Vision, across 1,000 images each, measuring metrics such as mAP@0.5, inference speed, FLOPs, and parameter count. To ensure a fair comparison, all images were resized to 800×800 pixels and evaluated using identical preprocessing, confidence thresholds, and IoU-based matching criteria.
mAP@0.5: Mean Average Precision at an Intersection over Union (IoU) threshold of 0.5, measuring the accuracy of object detection by balancing true positives and false positives.
Latency (ms): The average processing time per image, measured in milliseconds, indicates the model’s speed.
GPT-4o’s object detection capabilities remain limited compared to specialized models like YOLOv8n and DETR.
Accuracy:
These results indicate that GPT-4o is not yet suitable for practical object detection tasks.
Latency:
YOLOv8n offers the fastest inference but lower accuracy, while DETR achieves better accuracy at the cost of slower processing.
All models were evaluated using 800×800 input images for consistency. Parameter counts and FLOPS were available for YOLOv8n and DETR but not for GPT-4o, preventing a complete comparison of computational efficiency.
Model Complexity:
This shows YOLOv8n’s efficiency for real-time applications, while DETR trades speed for higher accuracy and greater computational demand. The lack of architectural details for GPT-4o limits deeper efficiency analysis.
See our benchmark methodology.
The three models showed different levels of accuracy and speed because they are built for different purposes and process visual information in distinct ways. GPT-4o is a multimodal large language model that accepts both text and images, whereas YOLOv8n and DETR are object detection systems that operate only on images.
GPT-4o interprets visual inputs through a language-driven reasoning pipeline. It can describe scenes and identify objects, but it is not designed to draw bounding boxes or perform high-precision spatial localization.
Its outputs depend on multimodal reasoning rather than detection-specific mechanisms. This makes it slower and less accurate for detection tasks.
YOLOv8n and DETR use architectures explicitly created for object detection. They generate bounding boxes directly rather than reasoning about them.
YOLOv8n is optimized for speed with a lightweight structure, while DETR is a transformer-based detector that processes images differently from YOLO and aims for more accurate predictions.
Both models focus solely on visual inputs and follow training objectives that map image patterns to object locations.
Key differences include:
Because YOLOv8n and DETR were developed solely for object detection, they naturally perform better in benchmarks focused on accuracy and latency.
GPT-4o’s broad, non-detection-centered multimodal design results in lower mAP and higher inference times when evaluated in the same setting.
GPT-4o (Vision) is a multimodal extension of OpenAI’s GPT-4, designed to process and generate responses from both text and images.
This capability allows GPT-4o to interpret visual content alongside textual information, enabling a range of applications that require understanding and analyzing images.
Despite its advanced capabilities, GPT-4o can sometimes produce inaccurate or unreliable outputs. It can misinterpret visual elements, overlook details, or generate incorrect information, requiring human verification for critical tasks.
The model may also reflect biases present in its training data, leading to skewed interpretations or reinforcing stereotypes. This is a concern in sensitive applications where impartiality is crucial, including demographic inference or content moderation.
Sora is a text-to-video model created by OpenAI. It generates short video clips from user prompts and can also extend existing videos. Its underlying technology is an adaptation of the DALL-E 3 model.
Sora is a diffusion transformer, a denoising latent diffusion model that uses a Transformer. Videos are initially generated in a latent space by denoising 3D “patches,” then converted to standard space using a video decompressor.
Re-captioning is used to enhance the training process, in which a video-to-text model generates detailed captions for videos.
With the latest developments, users can now generate videos up to 1080p resolution, with a maximum duration of 20 seconds, and in widescreen, vertical, or square aspect ratios. They can also incorporate their assets to extend, remix, and blend existing content or create new videos from text prompts.

LandingLens simplifies the development and deployment of computer vision models. It caters to various industries without requiring deep AI or complex programming expertise.
The platform standardizes deep learning solutions, reducing development time and enabling easy global scaling of projects. Without impacting production speed, users can build their own deep learning models and optimize inspection accuracy.
It offers a step-by-step user interface that simplifies the development process.
Figure 2: The diagram illustrates the LandingLens AI workflow, where input images are processed into data, used to train models, deployed via cloud, edge, or Docker, and continuously improved through feedback.2
Stable Diffusion is a deep learning model designed to create high-quality images from textual descriptions:
Stable Diffusion utilizes a latent diffusion model to improve efficiency. Instead of working directly with high-resolution images, it first compresses them into a lower-dimensional latent space using a variational autoencoder (VAE).
This approach significantly reduces computational demands, enabling running on consumer hardware with GPUs.
In addition to generating images from text, Stable Diffusion can be used for various creative tasks, such as:
Midjourney is an art generator that converts text descriptions into high-quality images.
Midjourney Version 7 features a completely rebuilt architecture with significant improvements in quality and functionality.
Image generation: V7 produces upscaled images at 2048 x 2048 pixels with exceptional prompt precision and near-photographic quality. Key improvements include richer textures, accurate rendering of complex elements like hands and faces, and sophisticated understanding of lighting and composition.
Video generation: Creates 5-21 second video clips with high frame-to-frame consistency. The system generates approximately 60 seconds of video from six images in roughly three hours, targeting professional applications in marketing, filmmaking, and content creation.
3D capabilities: Text-to-3D generation using NeRF-like modeling creates volumetric objects and immersive scenes. These features support game development, product visualization, and architectural applications.

DeepMind’s Flamingo is a vision-language model designed to understand and reason about images and videos using minimal training examples (few-shot learning). Here are some of the key features:
Flamingo uses frame-wise processing, breaking down videos into key frames and extracting information to efficiently analyze visual elements.
Its context-aware responses help generate captions, descriptions, and answers based on the progression of events within a video to ensure a coherent understanding of the content.
Additionally, Flamingo exhibits temporal reasoning to comprehend sequences, cause-and-effect relationships, and complex interactions over time. This makes it highly effective for video analysis and multimodal reasoning tasks.
CLIP is a neural network trained on a variety of images and text captions.
This model can perform various vision tasks, including zero-shot classification, by understanding images in the context of natural language.
CLIP is trained on 400 million (image, text) pairs to effectively bridge the gap between computer vision tasks and natural language processing. This helps CLIP make caption predictions or image summaries without being explicitly trained for these specific tasks.

Vision Transformer applies the transformer architecture originally used in natural language processing to image recognition tasks.
It processes images in a manner similar to how transformers process sequences of words, and it has shown effectiveness in learning relevant features from image data for classification and analysis tasks.
In Vision Transformer, images are treated as a sequence of patches. Each patch is flattened into a single vector, similar to how word embeddings are used in transformers for text.
This approach allows ViT to learn the image’ structure and independently predict class labels.
Video-native foundation models represent a fundamental shift from traditional computer vision approaches. Unlike earlier systems that processed videos as sequences of independent frames, these models treat time as an integral dimension of visual data.
OpenAI’s Sora exemplifies this evolution through its diffusion transformer architecture:

Medical imaging:
Security and surveillance:
Despite progress, several limitations persist:
Edge deployment enables vision models to run locally on smartphones, IoT devices, and embedded systems, eliminating dependence on cloud infrastructure.
Privacy benefits:
Performance advantages:
Cost efficiency:
Making large vision models viable on edge devices requires sophisticated optimization:
Large vision models (LVMs) are designed to process, analyze, and interpret visual data, such as images or videos. They are characterized by their extensive number of parameters, often in the millions or billions. This enables them to learn intricate patterns, features, and relationships in visual content.
Like large language models (LLMs) for text, LVMs are trained on vast datasets, which equip them with object recognition, image generation, scene understanding, and multimodal reasoning (integrating visual and textual information) capabilities.
These models can support applications in areas such as autonomous driving, medical imaging, content creation, and augmented reality.
Large vision models are built using advanced neural network architectures. Originally, Convolutional Neural Networks (CNNs) were predominant in image processing due to their ability to efficiently handle pixel data and detect hierarchical patterns.
Recently, transformer models, which were initially designed for natural language processing, have also been adapted for many different vision tasks, offering improved performance in some scenarios.
Training large vision models involves feeding them visual data, such as internet images or videos, along with relevant labels or annotations in the novel sequential modeling approach. Trainers label image libraries to feed the models.
For example, in image classification tasks, each image is labeled with the class it belongs to. The model learns by adjusting its parameters to minimize the difference between its predictions and the actual labels.
This process requires significant computational power and a large, diverse dataset to ensure the model can generalize well to new and unseen data.

Model Type refers to a vision model’s architecture and design principles. It defines how the model processes and interprets visual data, whether it integrates multiple modalities (e.g., text and images), and what underlying mechanisms (e.g., transformers, contrastive learning, diffusion) it employs to extract meaningful representations:
Training objective: The goal or optimization function that guides how a model learns from data. It determines how the model adjusts its internal parameters during training to improve performance on specific tasks. These are predicting the next data point (autoregressive), distinguishing similar/dissimilar inputs (contrastive learning), or classifying images into categories:
Fine-tuning Support: The ability of a model to be adapted to specific tasks by training on smaller, domain-specific datasets while retaining knowledge from its pre-training phase.
Fine-tuning helps improve performance on specialized applications.
Zero-shot/Few-shot Learning: The capability of a model to perform tasks with little to no task-specific training data.
Zero-shot learning allows inference on unseen categories, while few-shot learning enables adaptation with minimal labeled examples.
Multimodal Support: The ability of a model to process and integrate information from multiple modalities (e.g., text, images, audio).
Open-source vs. Proprietary: Open-source models have publicly available code and weights, allowing modification and deployment by the community,
Proprietary models are owned and controlled by private entities, can limit access and customization.
Edge Deployment: The ability of a model to run on edge devices (e.g., mobile phones, IoT devices) rather than relying on cloud-based servers.
Edge deployment helps reduce latency, enhances privacy, and enables real-time processing in resource-constrained environments.

Training and deploying these models require significant computational power and memory, which can make them resource-intensive.
They need vast and diverse datasets for training. Collecting, labeling, and processing such large datasets can be challenging and expensive. However, crowdsource companies can help handle this.
Models can inherit biases present in their training data, leading to unfair or unethical outcomes, particularly in sensitive applications like facial recognition.
Understanding how these models make decisions can be difficult, which concerns applications where transparency is critical. Check out explainable AI to learn how this process works and how it serves AI ethics.
While they perform well on data similar to their training set, they may struggle with completely new or different data types.
Using large visual models, especially in surveillance and facial recognition, raises significant privacy concerns.
Ensuring that these models comply with legal and ethical standards is increasingly important, particularly as they become more integrated into society.
In this benchmark, the performances of the object detection models YOLOv8n, DETR (DEtection TRansformer), and GPT-4o Vision were compared on the COCO 2017 validation dataset. 1000 images per model were used for the comparison. All images were resized to 800×800 pixels to ensure consistent input dimensions across models.
The YOLOv8n model was loaded with pretrained weights (yolov8n.pt) from the Ultralytics repository and inference was performed using the predict() method via the Ultralytics YOLO API. The DETR model was loaded with the detr_resnet50 architecture from the Facebook Research library, and its outputs, originally normalized in [center_x, center_y, width, height] format, were rescaled and converted to the [x1, y1, x2, y2] coordinate format. A confidence threshold of 0.5 was applied to the results of both models.
The GPT-4o Vision model was evaluated using OpenAI’s API for object detection capabilities. For this model, images from the COCO validation dataset were downloaded, annotations were loaded, and each image was converted to the appropriate format (resized to 800×800 pixels) before being sent to the API. Only detections belonging to COCO classes were requested in JSON format, and predictions returned by the API were evaluated using the same confidence threshold (0.5) and coordinate format.
In the evaluation, the models’ predicted bounding boxes were compared with ground truth boxes by calculating the Intersection over Union (IoU), with IoU ≥ 0.5 considered a true positive match. Average Precision (AP) was calculated for each class, and the mean of all classes was reported as the mAP@0.5 metric. Besides accuracy, inference times were measured and compared. Additionally, model complexity was analyzed based on FLOPs and total parameter counts.
To ensure a fair comparison, all model inferences were performed on the same hardware (identical GPU/CPU). The same preprocessing steps, resizing all images to 800×800 pixels and applying necessary normalization, were applied across all models. For post-processing, predictions were converted to the same coordinate format, a 0.5 confidence threshold was consistently applied, and uniform IoU calculation criteria were adopted during evaluation.
Within this framework, YOLOv8n, DETR, and GPT-4o Vision model were compared in terms of object detection performance and speed; additional adjustments and methods were employed to benchmark GPT-4o Vision’s capabilities against current object detection models.
Large vision models (LVMs) are changing how machines interpret and act upon visual data across various domains, including healthcare, autonomous systems, security, and the creative industries.
By leveraging advanced architectures, such as transformers and diffusion models, LVMs support a wide range of complex tasks, including medical imaging, real-time object detection, text-to-image generation, and video generation.
Their ability to learn from vast, multimodal datasets enables flexible deployment scenarios, ranging from cloud-based inference to edge computing, allowing for tailored applications that span from industrial inspection to personalized content creation.
However, these capabilities come with significant challenges. The computational cost of training and deploying LVMs remains high, often requiring powerful hardware and specialized infrastructure.
Issues such as data bias, limited interpretability, and ethical concerns surrounding surveillance and privacy underscore the need for careful model governance. As LVMs continue to evolve, striking a balance between innovation and responsibility will be crucial to ensure they are utilized effectively and equitably across various sectors.
