What Is GPT Image 1.5?
GPT Image 1.5 is OpenAI's latest image generation model, released December 2025. It powers the ChatGPT Images interface and is available via API. It represents a major speed and cost improvement over GPT Image 1 while maintaining or exceeding quality.
The model is accessible to all ChatGPT users (including trial-credit tier) through a dedicated Images interface. On ComfyUI Web, you can access it directly without any OpenAI subscription — through our API integration.
Editing Capabilities
GPT Image 1.5's editing stands out for its precision. When you request a change — swap a shirt color, add sunglasses, change the background — the model preserves everything else: lighting conditions, facial identity, hand positions, fabric textures.
Practical applications include: clothing and hairstyle try-ons, product mockup variations, architectural style changes, seasonal transformations, and creative filters that alter mood without changing composition.
GPT Image vs DALL-E
GPT Image 1.5 is the successor to OpenAI's image generation line that included DALL-E 2 and DALL-E 3. While DALL-E focused on pure text-to-image generation, GPT Image integrates more tightly with the GPT language model for better instruction understanding.
The key improvement over DALL-E 3 is editing precision — GPT Image 1.5 modifies exactly what you ask while preserving the rest, where DALL-E often regenerated the entire image. Speed is also dramatically improved (4x faster than GPT Image 1).
GPT Image 1.5 vs Open-Source Alternatives
Flux Dev offers LoRA fine-tuning, broader community tooling, and full transparency. GPT Image 1.5 provides better out-of-the-box instruction following and faster generation.
Seedream V5 matches GPT Image 1.5 on speed and surpasses it on Chinese text rendering. Nano Banana 2 competes on world knowledge accuracy. On ComfyUI Web, all are available free — try each and compare results on the same prompt.
Frequently Asked Questions
- Is GPT Image 1.5 available on ComfyUI Web?
- Yes. You get trial credits to generate images. No ChatGPT subscription or OpenAI account needed.
- How is GPT Image 1.5 different from DALL-E 3?
- GPT Image 1.5 is 4x faster, has precise editing that preserves unmodified elements, better instruction following, and improved text rendering. It's the evolution of OpenAI's image generation line.
- Can GPT Image 1.5 edit existing images?
- Yes. Upload an image and describe changes. The model modifies specific elements while preserving lighting, composition, and identity of unchanged areas.
- What resolution does GPT Image 1.5 support?
- Standard output is high-resolution suitable for digital use. Exact resolution depends on the generation mode and prompt.
- Do I need a ChatGPT Plus subscription?
- Not on ComfyUI Web. Our API integration provides direct access to GPT Image 1.5 with trial credits. On ChatGPT, it's available to all users including trial-credit tier.
- How does pricing compare to using ChatGPT directly?
- On ComfyUI Web, you pay with credits (trial-credit tier available). Via OpenAI's API, GPT Image 1.5 costs 20% less than GPT Image 1. ComfyUI Web's credit system often works out cheaper for moderate usage.
