GPT-5.5

GPT-5.5 is OpenAI's frontier model designed for complex professional workloads, building on GPT-5.4 with stronger reasoning, higher reliability, and improved token efficiency on hard tasks. It features a 1M+ token context window (922K input, 128K output) with support for text and image inputs, enabling large-scale reasoning, coding, and multimodal workflows within a single system.

GPT Image 2

OpenAI's second-generation image model. Near-perfect typography (including non-Latin scripts), 2x faster than gpt-image-1.5, up to 2K resolution, and 'thinking' over the prompt for dense compositions.

GPT-5.3 Chat

GPT-5.3 Chat is an update to ChatGPT's most-used model that makes everyday conversations smoother, more useful, and more directly helpful. It delivers more accurate answers with better contextualization and significantly reduces unnecessary refusals, caveats, and overly cautious phrasing that can interrupt conversational flow. The model is more willing to engage with nuanced topics, produces cleaner and more natural prose, and maintains strong performance across reasoning, coding, and creative tasks while feeling less robotic in casual interaction.

GPT Image 1.5

OpenAI's latest image generation model with strong instruction following, optional transparent backgrounds, and quality controls.

GPT Image 1.5 (Low)

GPT Image 1.5 with `quality=low` for faster and cheaper generations.

GPT Image 1.5 (Medium)

GPT Image 1.5 with `quality=medium` for balanced cost and quality.
