Available OpenAI image models (verified live via /v1/models 2026-05-15)
| Model ID | Notes |
|---|---|
gpt-image-2 |
Flagship. Released 2026-04-21. Best prompt adherence, best photorealism. Default when image quality matters. |
gpt-image-2-2026-04-21 |
Pinned dated variant of gpt-image-2 |
gpt-image-1.5 |
Intermediate release between 1 and 2 |
gpt-image-1-mini |
Smaller/cheaper gpt-image-1 variant — use for batch/draft generation where cost matters |
gpt-image-1 |
Original gpt-image. Still works; superseded by gpt-image-2. |
chatgpt-image-latest |
Always-current alias of the model ChatGPT.com uses (currently gpt-image-2-class). Use when you want "whatever ChatGPT uses today" |
dall-e-3 |
Legacy fallback. Different quality semantics (standard/hd, not low/medium/high). |
Pass any of these to --model. The script branches on gpt-image* for the quality/format handling, so all gpt-image-* variants work out of the box.
Default in the script is now gpt-image-2 (the flagship) — pass --model gpt-image-1-mini for cheap batch/draft work.
Quick Usage
Generate with OpenAI gpt-image-2 (flagship)
python ~/.agents/tools/generate-image.py \
--prompt "a sunset over mountains, oil painting style" \
--output ./sunset.png \
--model gpt-image-2 \
--quality high
Generate with default (gpt-image-2)
python ~/.agents/tools/generate-image.py \
--prompt "a sunset over mountains, oil painting style" \
--output ./sunset.png
High quality
python ~/.agents/tools/generate-image.py \
--prompt "modern logo design for a tech company" \
--output ./logo.png \
--size 1024x1024 \
--quality high
Wide format (good for blog covers, banners)
python ~/.agents/tools/generate-image.py \
--prompt "abstract digital art with blue tones" \
--output ./banner.png \
--size 1536x1024
Tall format (good for mobile, stories)
python ~/.agents/tools/generate-image.py \
--prompt "portrait of a futuristic city" \
--output ./city.png \
--size 1024x1536
Transparent background (icons, logos)
python ~/.agents/tools/generate-image.py \
--prompt "a minimalist cat icon, flat design" \
--output ./icon.png \
--background transparent
Generate with Stability AI (SD 3.5 Large)
python ~/.agents/tools/generate-image.py \
--prompt "watercolor painting of a garden" \
--output ./garden.png \
--provider stability
