Currently the strongest model for image generation; best-in-class when quality is the primary priority. Not an optimal choice if budget is tight or latency is critical—consider DALL-E 3 or Flux compact as alternatives instead.
強項
- Generates detail-rich, highly aesthetic images, handling complex prompts with natural intuition for composition, color palette, and style
- Top-tier image editing (inpainting, outpainting, object replacement), suitable for professional editorial and advertising workflows
- Strong generalization across domains—from photorealism to stylized art, conceptual, and fantasy styles
弱項
- High per-request cost; not suitable for high-volume projects or constrained budgets
- Slower inference latency than open-source alternatives (speed vs. quality tradeoffs should also be considered compared to DALL-E 3)
- Prompt parsing has limits (does not handle deep reasoning or overly compound requirements)—requires concise, clear prompts
適用情境
指南與影片
GPT Image 2 (high) is OpenAI's flagship AI image generation model launched in April 2026, accessible via ChatGPT or the OpenAI API with the `quality: "high"` parameter. It is best suited for marketing assets, posters, product photography, and UI mockups requiring precise in-image text rendering (~99% accuracy for Latin and CJK scripts). When using the API, test prompts with `quality: "low"` first and only switch to `"high"` for final outputs, as it costs ~$0.211 per 1024×1024 image. With integrated O-series reasoning, concise prompts yield strong results—the model plans image layout and structure before rendering.
