What it is
GPT Image 1.5 is OpenAI's mid-tier image generation model. It sits between the flagship GPT Image 2 (highest fidelity) and lighter options, offering a balance of output quality and generation speed. On PlugNode, GPT Image 1.5 is available on the Image node. Select it from the model dropdown, set the prompt, paste your OpenAI API key in Settings, and the node returns an image. It is the right pick for product photography, social media creatives, and catalog imagery where consistent quality matters but turnaround time drives the schedule. Every request hits OpenAI's API with your own key. No proxy, no credit system, no markup.
What you can do with it
- Generate product images from a text prompt
- Produce social media creatives and ad visuals
- Batch-generate catalog imagery for e-commerce listings
- Chain with a Text node for prompt scripting and iteration
- Wire into Image Resize for multi-platform output (Instagram, TikTok, Shopify)
- Return the image URL directly to a webhook caller via Respond to Webhook
- Publish the full pipeline as a signed API endpoint
When to pick GPT Image 1.5
GPT Image 1.5 is the middle option in OpenAI's image generation lineup. It generates faster and costs less than GPT Image 2, while producing output that holds up for product imagery, social media creatives, and catalog listings. If you are running a weekly content calendar and need 20 to 50 images per batch, 1.5 keeps the cost and turnaround practical without dropping to a lower-quality tier.
The model handles product shots on clean backgrounds, lifestyle scenes with styled environments, and branded ad creatives. For hero images on a landing page or a flagship campaign, GPT Image 2 is the better choice. For everything else in the content pipeline, 1.5 does the job.
Running GPT Image 1.5 on PlugNode
Drop an Image node on the canvas, select GPT Image 1.5 from the model dropdown, and paste your OpenAI API key in Settings. Wire a Text node before it (Gemini or GPT-4.1) to turn a short product brief into a detailed prompt. Add an Image Resize node after it to produce Shopify, Instagram, and TikTok crops from a single generation. End with Respond to Webhook and publish the flow. Your store or CMS can POST to the endpoint and get back image URLs.
Every request hits OpenAI's API with your key. PlugNode does not proxy the request, add per-image markup, or run a credit system. For the full pattern, see the publish-as-API pillar and the OpenAI Image integration.
GPT Image 1.5 vs Nano Banana Pro
Both models are available on the Image node dropdown. GPT Image 1.5 runs on OpenAI infrastructure. Nano Banana Pro runs on Google Gemini infrastructure. They produce different visual styles, and the best pick depends on your brand aesthetic. A practical approach: generate the same prompt on both, compare the results, and lock in the model that fits. Switching between them is a dropdown change with no downstream rewiring.
