OpenAI's Models: All Versions Compared
OpenAI's image generation evolved from DALL·E 3 to GPT-Image-1, enhancing prompt comprehension, text rendering, and multimodal integration, enabling seamless conversational image creation and refinement within ChatGPT.
OpenAI's Models is OpenAI's AI generation suite — covering both AI image generation and AI video generation at the frontier of the field. From GPT-4o's native image generation with precise multi-element prompt following to Sora 2's physically accurate video with synchronized dialogue and sound effects, OpenAI's models represent some of the most consequential benchmarks in generative media.
What you can create with OpenAI's models
-
Images from text with precise prompt adherence
GPT-4o's native image generation excels at accurately following complex multi-element prompts, rendering text within images, and leveraging GPT-4o's vast knowledge base. GPT Image 1.5 marked a further step-change in image quality and edit consistency over earlier GPT-4o image outputs.
-
Images from image editing and transformation
GPT-4o image generation can transform uploaded images or use them as visual inspiration — editing, reimagining, or extending existing visuals through conversational prompts within the ChatGPT interface. DALL·E remains accessible through a dedicated GPT for users who prefer its specific aesthetic.
-
Physically accurate video from text
Sora 2 (released September 30, 2025) generates high-fidelity video described as "more physically accurate, realistic, and controllable than prior systems." Objects, characters, and environments behave with plausible real-world physics and temporal coherence across the full clip.
-
Video with synchronized dialogue and audio
Sora 2 generates synchronized dialogue, sound effects, and temporal audio coherence alongside the video output — producing complete media assets from a single prompt via the new Video API.
-
Licensed character and IP generation
OpenAI's Disney partnership (announced December 2025, a $1 billion investment) enables Sora 2 to generate characters from over 200 Disney, Pixar, Marvel, and Star Wars IP within authorized workflows — marking a significant expansion of AI video generation into licensed entertainment production.
Why creators choose OpenAI's models
-
Best-in-class text rendering in images
GPT-4o image generation leads the field in rendering readable, correctly spelled text within images — a persistent weakness of earlier image generation models. For creators producing social graphics, marketing assets, or any content where text within images must be legible, GPT-4o image generation is the quality benchmark.
-
Conversational image editing
Because image generation is native to GPT-4o, creators can edit and refine outputs through natural conversation — describing changes, referencing earlier turns, or asking GPT-4o to apply knowledge from its training to enhance the image. This iterative conversational workflow is unique to OpenAI's model architecture.
-
Physical accuracy in video generation
Sora 2 is built on a diffusion transformer architecture enhanced by GPT to expand prompts into detailed captions before generation, delivering unusually coherent physics simulation — objects move with realistic weight and force, and environments behave consistently across the full video duration.
-
Diffusion transformer architecture
OpenAI's image and video models are built on a diffusion transformer architecture — the same family of architectures used by FLUX and Stable Diffusion 3.5. For Sora, this architecture is enhanced by a denoising latent diffusion model that GPT-4o first expands into a detailed generation prompt.
-
Broad platform access through ChatGPT
GPT-4o image generation and DALL·E are accessible across all ChatGPT tiers — including the Free tier — making OpenAI's image models the most widely accessible frontier image generation capability in the world. Sora 2 is available to ChatGPT Pro subscribers and via the Video API for developers.
How to access OpenAI's image and video models
- Access through ChatGPT. GPT-4o image generation and DALL·E are available at chatgpt.com across Free, Plus, Pro, and Team tiers. Sora 2 for video generation is available to ChatGPT Pro subscribers and through the OpenAI Video API. Enterprise access is available via Microsoft Azure.
- Choose your generation type. Use GPT-4o image generation for text-to-image and image editing through conversational prompts. Use the dedicated DALL·E GPT for DALL·E-specific aesthetic output. Access Sora 2 through the Sora tab in ChatGPT Pro for AI video generation.
- Enter your prompt and generate. Write your prompt in the ChatGPT interface and generate. All Sora 2 video outputs carry a visible, moving digital watermark. To compare similar AI image and video models, browse the models available on AI Compare Hub.
Common questions
What AI models does OpenAI offer for image and video generation?
OpenAI's generation model family includes GPT-4o native image generation and GPT Image 1.5 for text-to-image and image editing, DALL·E (accessible via a dedicated ChatGPT GPT), and Sora 2 for AI video generation with synchronized audio. All are accessible through ChatGPT, with Sora 2 and API access requiring paid subscription tiers.
What is the difference between GPT-4o image generation and DALL·E?
GPT-4o's native image generation leverages GPT-4o's full conversational context and knowledge base — enabling complex multi-element prompt following, text rendering accuracy, and iterative conversational editing. DALL·E is OpenAI's earlier dedicated image model, accessible through a separate ChatGPT GPT, with its own distinct aesthetic and generation characteristics. GPT-4o image generation is now OpenAI's primary image model and the default in ChatGPT.
What is Sora 2?
Sora 2 (released September 30, 2025) is OpenAI's most advanced AI video model — described as "more physically accurate, realistic, and controllable" than earlier Sora models. It generates high-fidelity video with synchronized dialogue, sound effects, and temporal audio coherence via a new Video API. All Sora 2 outputs carry a visible, moving digital watermark. It is available to ChatGPT Pro subscribers and enterprise developers.
Which OpenAI model is best for AI image generation?
GPT-4o native image generation (including GPT Image 1.5) is OpenAI's current flagship for image generation — recommended for complex multi-element prompts, text rendering within images, and iterative conversational editing workflows. DALL·E is the alternative for users who prefer its specific aesthetic or were already using it for existing workflows.
How can you access OpenAI's AI models?
OpenAI's image and video models are accessible through ChatGPT at chatgpt.com, with GPT-4o image generation available on the Free tier and Sora 2 available to Pro subscribers. OpenAI's models are not currently available for direct comparison on AI Compare Hub.
