GPT-5.4 Nano is the smallest and fastest variant of GPT-5.4, designed for high-throughput, low-latency tasks such as classification, data extraction, ranking, and lightweight automation. It prioritizes speed and cost efficiency for simple, high-volume workloads and is available exclusively via the API.

GPT-5.4 Mini is a compact, efficient variant of GPT-5.4 designed for coding assistants, subagent orchestration, and multimodal applications requiring faster responsiveness. It supports a 400K token context window and retains native computer use and configurable reasoning effort at a lower cost than the flagship model.

GPT-5.4 Pro is the high-performance variant of GPT-5.4, optimized for enterprise-grade professional tasks. It offers deeper reasoning, enhanced accuracy, and extended compute for complex multi-step workflows including document creation, spreadsheet analysis, and autonomous agent orchestration. It shares the 1 million token context window and native computer use capabilities of the standard GPT-5.4.

GPT-5.4 is OpenAI's flagship large language model, featuring a 1 million token context window, native computer use, and a 33% reduction in factual errors over GPT-5.2. It integrates coding capabilities from GPT-5.3-Codex, is 47% more token-efficient, and supports configurable reasoning effort for complex professional tasks.

GPT Image 1.5 is OpenAI’s newest flagship image model powering the latest ChatGPT Images. It delivers significantly faster image generation with stronger instruction following, more precise edits that preserve original details, more believable transformations, and improved rendering of dense or small text. It is suited for practical creative workflows, detailed design tasks, and production use cases.

Sora 2 is OpenAI’s flagship generative model for video and audio. It accepts text prompts and generates visually rich clips with synchronized dialogue and sound. It improves physical realism and scene control. It also supports editing and extension of existing video inputs.

Sora 2 Pro is the higher quality Sora 2 variant for precision video work. It supports text prompts and image inputs. It outputs synchronized video with sound, higher resolution frames, and stronger temporal consistency. Ideal for production clips and demanding pipelines.

GPT Image 1 Mini is a lighter variant of OpenAI's GPT Image 1 model. It offers faster generation at a lower cost while retaining core capabilities including text-to-image generation, image editing, and text rendering. It is suited for high-volume workflows, rapid prototyping, and cost-sensitive applications where the full GPT Image 1 model may be excessive.

DALL·E 3 converts natural language prompts into detailed images with strong caption fidelity. It improves handling of complex instructions and visual details. It integrates with ChatGPT and the OpenAI API for programmatic image creation and workflow automation.

DALL·E 2 is OpenAI’s diffusion based text to image model. It generates high quality images from prompts. It supports inpainting for local edits and outpainting for extended canvases. Developers use it through an API for creative tools, design workflows, and content pipelines.

OpenAI CLIP ViT-L/14 is a contrastive vision-language model that embeds images and text into a shared representation space. It enables tasks like zero-shot image classification, semantic search, and similarity scoring by computing aligned feature vectors for images and texts.
