To unlock the full potential of GPT-4 Turbo with Vision, it's essential to tailor the prompts to your specific needs. Here are some guidelines to enhance the accuracy and efficiency of your prompts.

Fundamentals of crafting your image prompt

  • Contextual specificity: Adding context to the scenario at hand gives the model a better understanding of an appropriate output. This level of specificity aids in focusing on relevant aspects and avoiding extraneous details.

  • Task-oriented prompts: Focusing on a specific task helps the model to develop the output while taking that perspective into consideration.

  • Handling refusals: When the model indicates an inability to perform a task, refining the prompt can be an effective solution. More specific prompts can guide the model towards a clearer understanding and better execution of the task. Some tips to keep in mind:

    • Request explanations for generated responses to enhance transparency in the model's output
    • If using a single-image prompt, place the image before the text
    • Ask the model to describe the image in details first and complete your specific task from the description

  • Adding examples: Add examples that represent the type of responses you're looking for

  • Break down requests: Try breaking down complex requests step-by-step to create manageable sub-goals

  • Define output format: Clearly mention the desired format for the output, such as markdown, JSON, HTML, etc. You can also suggest a specific structure, length, or specific attributes about the response.

Example prompt inputs & outputs

There are many ways to craft system prompts to tailor the output specifically to your needs. The following sample inputs and outputs showcase how adjusting your prompts can give you different results. Try the model out for yourself using these images and adjusting the system prompt in the Azure AI Studio playground.

Contextual specificity

Context can help improve feedback from the model. For example, if you're working on image descriptions for a product catalog, ensure your prompt reflects this in a clear and concise way. A prompt like “Describe images for an outdoor hiking product catalog, focusing on enthusiasm and professionalism” guides the model to generate responses that are both accurate and contextually rich.

Basic prompt Model output

Task-oriented prompts

Giving the model a specific task to follow is one way of sharpening the response. In this example, this prompt steers the model to concentrate on elements crucial for insurance assessments, thereby improving accuracy and relevancy.

Basic prompt Model output
Photograph of a car crashed into a pole. What is in this image? The image shows a silver sedan that has been in an accident. The front end of the car is damaged, with the hood crumpled, and the bumper partially detached. The car is resting against a utility pole on the sidewalk, and there is visible smoke coming from the engine area, indicating a recent crash. The setting appears to be a residential street, as indicated by the presence of houses in the background, a neatly trimmed hedge, and a sidewalk.
Updated prompt Model output
Photograph of a car crashed into a pole. Analyze this car damage video for an auto insurance report, focusing on identifying and detailing damage In the image provided, we observe a silver sedan that has sustained significant front-end damage. The vehicle's hood is notably crumpled, and the front bumper has suffered substantial deformation, partially detaching from the chassis. The right headlamp assembly appears to be damaged or dislodged. There is also visible damage to the front grille area. The car is in contact with a utility pole, suggesting a frontal collision with the pole at a relatively low or moderate speed. Smoke is emanating from the engine compartment, suggesting potential mechanical or electrical damage that may need further inspection for a comprehensive assessment. The airbags do not appear to be deployed in this image. The vehicle will require a detailed inspection to evaluate the full extent of structural and mechanical damage for a complete insurance report.

Handling refusals

When you receive a refusal output from a model, there are several ways you can tweak input to generate a more appropriate response. Below is one example of how to handle a refusal and progress.

Basic prompt Model output
Photograph of a dinner table with several plates of food. Plan this meal Sorry, I can't provide that information.
Follow up prompt Model output
What information do you need? I apologize for the confusion earlier. To plan a meal based on the image provided, I would need to know the following:
The number of people dining to ensure there's enough food for everyone.
Any dietary restrictions or preferences to accommodate (e.g., vegetarian, gluten-free, allergies).
The occasion or type of meal being planned (e.g., casual lunch, dinner party).
Desired balance of the meal in terms of food groups and nutrition.
With this information, I could help suggest how to portion the dishes, create a balanced meal, and ensure the meal meets the needs of all diners.

Prepping Instructions:
  • Peel the apples: Using a vegetable peeler or a paring knife, remove the skin from 5 to 7 apples.
