DALL.E
Artificial intelligence has made significant strides in various fields, and one of its most important advancements is the ability to generate images from text descriptions. OpenAI's DALL·E is a prime example of this technology. In this Answer, we'll understand what DALL·E is, its architecture, how it works, and how you can implement it using the API.
Understanding DALL·E
DALL·E is an AI construct courtesy of OpenAI, engineered to create images from textual cues. It is an enhancement of the GPT-3 model, trained on a dataset consisting of text-image pairs. This training equips DALL·E to originate unique, imaginative visuals based on the text prompts it is given.
DALL·E's architecture
DALL·E relies on the transformer structure, similar to GPT-3, but is fine-tuned to create images instead of text. It’s essentially a 12-billion parameter variant of GPT-3, primed to form images from textual descriptions, utilizing a dataset of text-image pairs. This model has exhibited a wide range of abilities, including the generation of
How does it work?
DALL·E processes both the text and the image as a unified data stream encompassing up to 1280 tokens and is educated using maximum likelihood to produce all of the tokens sequentially. This training approach empowers DALL·E to not only generate an image from scratch but also to recreate any rectangular section of a pre-existing image that extends to the bottom-right corner, aligning with the text prompt.
DALL.E Pricing
Resolution | Price per image |
256×256 | $0.016 |
512×512 | $0.018 |
1024×1024 | $0.020 |
Using DALL·E via OpenAI lab interface
To utilize DALL·E via the OpenAI Lab interface, one has to first procure credits from OpenAI. 115 credits cost $15 dollars, and you can buy credits in multiples of 115.
Once you have credits in your possession, you can deploy them to create images. Simply provide a text prompt, and DALL·E will fashion an image following your cue.
Employing the DALL·E API
The DALL.E API can be used in Python. Here’s a basic illustration of generating an image:
import osimport openaiimport requestsopenai.api_key = os.environ["SECRET_KEY"]PROMPT = "a student on his desk"response = openai.Image.create(prompt=PROMPT,n=1,size="256x256",)url = response["data"][0]["url"]data = requests.get(url).content# Opening a new file named img with extension .jpg# This file would store the data of the image filef = open('output/img.png','wb')# Storing the image data inside the data variable to the filef.write(data)f.close()
Note: This code will only be executable when you enter your API key. To learn how to obtain OpenAI's API key, click here.
In this code snippet, we’re directing DALL·E to produce an image of a student on his desk. The n parameter specifies that we desire a single image and the size parameter implies we want the image size to be 256x256 pixels.
Example output
In case you're facing difficulties in executing the code due to the absence of an API key, below is the result obtained from a previous successful code execution.
The image you see above, generated by DALL.E, showcases its ability to draw multiple objects in a single image. When it comes to drawing multiple objects, DALL.E faces a new challenge in that it must control multiple objects, their attributes, and their spatial relationships simultaneously. For instance, in the image above, DALL.E has not only drawn a student, but also a desk, an apple, a notebook, and a pen, all in their appropriate spatial locations.
The ability to correctly interpret and execute such a prompt demonstrates DALL.E's capability to form associations between different objects and their attributes without mixing them up. However, it's important to note that as more objects are introduced, DALL.E can be prone to confusing the associations between the objects and their attributes, and the success rate may decrease.
Conclusion
DALL·E stands as a potent tool for creating and altering images via textual prompts. It opens the floodgates for creative applications, spanning art and design to advertising and entertainment. As with any AI tool, responsible usage within the confines of OpenAI's guidelines is paramount.
