Based [on this](https://developers.openai.com/api/docs/guides/image-generation#overview) I think Sunburst is the stronger option:\n\nChoose Sunburst for workflows where editing precision matters most, and Flare for fast, high-quality everyday image generation.\n\nI [upgraded](https://github.com/simonw/tools/pull/333) my [openai_image.py](https://tools.simonwillison.net/python/#openai_imagepy) CLI tool to support passing in one or more reference images, so now this works:\n\n```\nuv run https://tools.simonwillison.net/python/openai_image.py \\\n  'add a raccoon scientist studying the chart thoughtfully' \\\n  -i https://static.simonwillison.net/static/2026/openai-agent-usage.webp \\\n  -m gpt-image-2.5-sunburst\n```\n\nThis is the [original image](https://static.simonwillison.net/static/2026/openai-agent-usage.webp), and here's what I got back from that prompt to \"add a raccoon scientist studying the chart thoughtfully\":\n\nTags: [tools](https://simonwillison.net/tags/tools), [ai](https://simonwillison.net/tags/ai), [openai](https://simonwillison.net/tags/openai), [generative-ai](https://simonwillison.net/tags/generative-ai), [uv](https://simonwillison.net/tags/uv), [text-to-image](https://simonwillison.net/tags/text-to-image)", "url": "https://wpnews.pro/news/introducing-chatgpt-images-2-5", "canonical_source": "https://simonwillison.net/2026/Sep/8/introducing-chatgpt-images-25/", "published_at": "2026-09-08 22:46:33+00:00", "updated_at": "2026-09-08 23:02:32.168740+00:00", "lang": "en", "topics": ["generative-ai", "ai-products", "ai-tools"], "entities": ["OpenAI", "ChatGPT Images 2.5", "gpt-image-2.5-sunburst", "gpt-image-2.5-flare", "Simon Willison", "openai_image.py"], "alternates": {"html": "https://wpnews.pro/news/introducing-chatgpt-images-2-5", "markdown": "https://wpnews.pro/news/introducing-chatgpt-images-2-5.md", "text": "https://wpnews.pro/news/introducing-chatgpt-images-2-5.txt", "jsonld": "https://wpnews.pro/news/introducing-chatgpt-images-2-5.jsonld"}}
