**[Introducing ChatGPT Images 2.5](https://openai.com/index/introducing-chatgpt-images-2-5/)**
OpenAI's image generation models are apparently used "more than 3 billion images across ChatGPT Images and the GPT‑Image models in the API". This latest release improves their instruction-following ability across multiple turns, responds faster, and "is better at preserving the subjects in your reference photos".
There are two new model IDs in the API: `gpt-image-2.5-sunburst` and `gpt-image-2.5-flare`. Based [on this](https://developers.openai.com/api/docs/guides/image-generation#overview) I think Sunburst is the stronger option:
> Choose Sunburst for workflows where editing precision matters most, and Flare for fast, high-quality everyday image generation.
I [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:
```
uv run https://tools.simonwillison.net/python/openai_image.py \
'add a raccoon scientist studying the chart thoughtfully' \
-i https://static.simonwillison.net/static/2026/openai-agent-usage.webp \
-m gpt-image-2.5-sunburst
```
This 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":
