  • One of the key techniques used in Dall-E 2’s training is “attention.” This technique allows the model to focus on specific parts of the text description when generating an image. For example, if the text description includes the word “striped,” Dall-E 2 will pay extra attention to the patterns in the image to ensure they are correctly striped.
  • Another important technique in Dall-E 2’s training is “multi-modal fusion.” This technique allows the model to combine information from multiple sources, such as the image’s text description and visual features, to generate a more accurate image.
  • Dall-E 2 can generate images that go beyond the text description. This is thanks to a technique called “concept completion,” which allows the model to fill in missing details based on its understanding of the concepts in the text description.

These advanced techniques make Dall-E 2 one of the most impressive AI models for generating images. Its ability to create natural images depending on text descriptions has endless potential applications in advertising, design, and entertainment.

How Was Dall-E2 Trained?

Here, in running order, are the steps that OpenAi used to develop and train this convenient AI program.



Collecting Data

The first step in training Dall-E 2 was to collect a large dataset of images. This dataset included various photos of everyday objects along with more abstract concepts.



Generating Text Descriptions

Once you collected the dataset, text descriptions were generated for each image. These details describe each image briefly.



Training the Neural Network

The company trained Dall-E 2 using a neural network with the dataset and text descriptions in place. They trained the neural network to generate images that matched the text descriptions using “generative adversarial training.”



Fine-Tuning the Model

After the initial training, the developers further fine-tuned the model to improve its performance. This involved adjusting the neural network architecture and re-training it on the dataset.



Validating the Model

Finally, the company validated the model to ensure it produced the results according to the requirements. OpenAI used human evaluators to rate the images on a scale of 1 to 5 on the basis of how well they matched the text descriptions.

How Does Dall-E 2 Generate Images?

Dall-E 2 can generate images by using text descriptions as input. It does this by breaking down the text descriptions into smaller parts, such as objects and attributes, and then using these parts to generate the image.

For example, if the text description is “a red and green striped shirt,” Dall-E 2 will break this down into “shirt,” “red,” “green,” and “striped.” It will then use this information to generate an image of a red and green striped shirt.


OpenAI trained Dall-E 2 using a large dataset of images and text descriptions. The developers used this dataset to train a neural network to generate images. 

The company then fine-tuned and validated to ensure it generated high-quality images. By understanding how the company trained Dall-E 2, we can appreciate the impressive capabilities of this cutting-edge AI technology.

OpenAI has trained the AI model using advanced techniques to generate high-quality images based on text descriptions. Its capabilities are truly remarkable and will continue impacting various fields.
