Building on Previous Work
This approach to iterative ad image generation builds upon our previous article, "Iteratively Improving Product Images using GPT-V and Stable Diffusion", where we explored the foundations of AI-assisted design workflows. In that piece, we demonstrated how combining GPT-4's conceptual abilities with Stable Diffusion's image generation could streamline the creative process.
The current implementation with GPT-Image-1 represents a significant evolution of those concepts, offering tighter integration between text and image modalities while maintaining the core iterative improvement framework. Readers familiar with the previous approach will notice several key advancements:
- Unified API access through OpenAI's platform
- More precise editing capabilities rather than regeneration
- Improved conceptual understanding between iterations
- Streamlined workflow requiring fewer prompt engineering techniques
For those interested in comparing approaches or adapting this methodology to existing Stable Diffusion pipelines, the previous article provides valuable context and complementary techniques that can be integrated with the workflow described here.
In the fast-paced world of digital marketing, creating compelling ad visuals can be both time-consuming and resource-intensive. What if artificial intelligence could not only generate initial ad concepts but also progressively refine them based on intelligent feedback? Today, I'm excited to share a powerful approach to iterative ad image generation using OpenAI's GPT-Image-1 model.

Introducing the AI Image Editing Studio

I've developed a Streamlit application that harnesses the power of OpenAI's language and image models to generate, analyze, and progressively improve ad images. The tool takes basic marketing inputs and transforms them into polished ad visuals through an automated, iterative process.
How It Works
The application follows a structured workflow:
- Initial Concept Generation: Using GPT-4, the app creates a comprehensive ad concept including headline, primary text, call-to-action, and image instructions
- Base Image Creation: GPT-Image-1 creates an initial visual based on the concept
- Iterative Refinement: The system analyzes each version and suggests specific improvements
- Progressive Enhancement: Each iteration builds upon the previous, refining the image based on expert feedback
Let's dive into each component in detail.
Step 1: Generating the Ad Concept
The first step involves translating marketing inputs into a structured ad concept. The application takes three key inputs:
- Brand Information: Details about the brand, products, and unique selling propositions
- Target Audience: Demographic, psychographic, and behavioral characteristics
- Marketing Goal: Specific objectives the ad aims to achieve
These inputs are processed by GPT-4, which generates a comprehensive ad concept including:
def generate_ad_concept(brand_info, target_audience, marketing_goal):
"""Generate Facebook ad concept using GPT-4"""
st.info("Generating initial ad concept...")
prompt = f"""
Create a Facebook ad concept based on:
- Brand: {brand_info}
- Audience: {target_audience}
- Goal: {marketing_goal}
Return JSON with these fields:
- headline: Catchy headline (5-7 words)
- primary_text: Main ad copy (1-2 sentences)
- description: Additional context (optional)
- cta: Call-to-action (e.g., "Shop Now")
- image_edit_instructions: Detailed instructions for image editing
"""
try:
response = client.chat.completions.create(
model="gpt-4-turbo",
messages=[
{
"role": "system",
"content": "You are a professional ad copywriter. Return only valid JSON with all required fields."
},
{
"role": "user",
"content": prompt
}
],
response_format={"type": "json_object"},
temperature=0.7
)
result = json.loads(response.choices[0].message.content)
# Validate all required fields are present
required_fields = ['headline', 'primary_text', 'cta', 'image_edit_instructions']
if all(field in result for field in required_fields):
return result
else:
st.error(f"Missing required fields in response: {result}")
return None
except Exception as e:
st.error(f"Failed to generate concept: {str(e)}")
return None
The model returns a structured JSON object containing all the elements needed for the ad, including detailed instructions for creating the initial image.
Step 2: Creating the Initial Image
With the concept and image instructions in place, the application uses GPT-Image-1 to generate the first version of the ad image:
def generate_initial_image(prompt):
"""Generate initial image using GPT-Image-1"""
st.info("Generating initial image...")
try:
response = client.images.generate(
model="gpt-image-1",
prompt=prompt,
n=1,
size="1024x1024",
quality="low",
)
# Get the base64 encoded image directly
image_b64 = response.data[0].b64_json
return f"data:image/png;base64,{image_b64}"
except Exception as e:
st.error(f"Image generation error: {str(e)}")
return None
This function takes a simple white base image and transforms it according to the detailed instructions generated in the previous step. The result serves as our starting point for further refinement.
Understanding GPT-Image-1: The Engine Behind the Magic
GPT-Image-1 represents a significant advancement in AI-powered image generation and editing. Unlike previous models that could only generate images from text prompts, GPT-Image-1 can edit existing images based on natural language instructions.
Key Capabilities of GPT-Image-1:
- Contextual Understanding: The model comprehends both the visual content of an image and the semantic meaning of editing instructions
- Precision Editing: GPT-Image-1 can modify specific elements within an image while preserving the overall composition
- Style Adaptation: It can adjust visual styles, color schemes, and artistic elements based on text guidance
- Conceptual Translation: The model transforms abstract marketing concepts into appropriate visual representations
- Multimodal Reasoning: GPT-Image-1 bridges the gap between linguistic understanding and visual creation
In our application, we leverage GPT-Image-1's editing capabilities by providing:
- A base image (initially a blank canvas)
- Detailed editing instructions derived from marketing goals
- Low-quality settings for faster iteration cycles
The model then processes these inputs to generate a new image that aligns with the provided instructions while maintaining coherence and visual appeal.
Step 3: Analyzing and Improving
Here's where the magic happens. Rather than relying on human feedback, the application uses GPT-4's visual understanding capabilities to analyze the current image and suggest specific improvements:
def analyze_and_improve(image_b64, ad_concept, iteration):
"""Analyze ad and suggest editing improvements"""
st.info(f"Analyzing iteration {iteration}...")
critique_prompt = f"""
Analyze this Facebook ad (iteration {iteration}) and suggest improvements:
Current Ad:
- Headline: {ad_concept['headline']}
- Primary Text: {ad_concept['primary_text']}
- CTA: {ad_concept['cta']}
Provide specific feedback on:
1. Headline effectiveness and alternatives
2. Element additions/removals
3. Visual elements that need modification
4. Composition adjustments
5. Color scheme improvements
6. Element positioning optimizations
When suggesting instructions, be as specific as possible and ensure they are safe, professional, and suitable for all audiences.
Return JSON with:
- critique: Concise analysis addressing all points above
- recommendation: Either "edit" or "new" based on whether you recommend editing the current image or creating a new one
- edit_instructions: Detailed editing instructions if recommendation is "edit"
- generation_instructions: Detailed generation instructions if recommendation is "new"
- headline_variants: 3 improved headline options
"""
try:
response = client.chat.completions.create(
model="gpt-4-turbo",
messages=[
{
"role": "system",
"content": "You are an expert image editor. When providing instructions, ensure they are safe, professional, and suitable for all audiences."
},
{
"role": "user",
"content": [
{
"type": "image_url",
"image_url": {
"url": image_b64,
"detail": "low"
}
},
{
"type": "text",
"text": critique_prompt
}
]
}
],
response_format={"type": "json_object"},
max_tokens=1500
)
result = json.loads(response.choices[0].message.content)
# Validate response contains required fields
if 'critique' in result and 'recommendation' in result:
if result['recommendation'] == 'edit' and 'edit_instructions' not in result:
st.error("Missing edit instructions in critique response")
return None
elif result['recommendation'] == 'new' and 'generation_instructions' not in result:
st.error("Missing generation instructions in critique response")
return None
return result
else:
st.error(f"Missing required fields in critique: {result}")
return None
except Exception as e:
st.error(f"Analysis error: {str(e)}")
return None
The model provides detailed feedback and concrete editing instructions, focusing on aspects like:
- Visual element modifications
- Composition adjustments
- Color scheme improvements
- Element positioning
Step 4: Iterative Enhancement
With the analysis and editing instructions in hand, the application applies these changes to create an improved version of the image:
# Apply edit
def edit_image_with_prompt(base_image, edit_instructions):
"""Edit existing image using GPT-Image-1"""
st.info("Editing image based on feedback...")
try:
# Decode the base64 image data
image_data = base64.b64decode(base_image.split(",")[1])
# Save temporarily to file (OpenAI API requires a file)
with open("temp_image.png", "wb") as f:
f.write(image_data)
# Log the edit instructions
st.write("### Edit Instructions Sent to API")
st.write(edit_instructions)
# Open file for API
with open("temp_image.png", "rb") as img_file:
# Ensure edit_instructions is a string
if not isinstance(edit_instructions, str):
edit_instructions = str(edit_instructions)
response = client.images.edit(
model="gpt-image-1",
image=img_file,
prompt=edit_instructions,
n=1,
size="1024x1024"
)
# Get the base64 encoded image directly
image_b64 = response.data[0].b64_json
# Clean up temp file
if os.path.exists("temp_image.png"):
os.remove("temp_image.png")
return f"data:image/png;base64,{image_b64}"
except Exception as e:
st.error(f"Image editing error: {str(e)}")
# Clean up temp file if it exists
if os.path.exists("temp_image.png"):
os.remove("temp_image.png")
return None
This process repeats for a specified number of iterations (configurable by the user), with each version building upon the improvements of the previous one. The result is a progressively refined ad image that aligns with marketing best practices and the specific campaign objectives.
