The right way to Generate and Edit Photographs Utilizing OpenAI gpt-image-1 API

The final time OpenAI’s ChatGPT launched a picture era mannequin, it shortly went viral throughout the web. Folks had been captivated by the power to create Ghibli-style portraits of themselves, turning private reminiscences into animated art work. Now, ChatGPT is taking issues a step additional with a brand new natively multimodal mannequin “gpt-image-1” which powers picture era straight inside ChatGPT and is now out there by way of API. On this article we’ll discover the important thing options of OpenAI’s gpt-image-1 mannequin and learn how to use it for picture era and enhancing.

What’s gpt-image-1?

gpt-image-1 is the newest and most superior multimodal language mannequin from OpenAI. It stands out for its potential to generate high-quality photographs whereas incorporating real-world information into the visible content material. Whereas gpt-image-1 is advisable for its sturdy efficiency, the picture API additionally helps different specialised fashions like DALL·E 2 and DALL·E 3.

The Picture API affords three key endpoints, every designed for particular duties:

• Generations: Create photographs from scratch utilizing a textual content immediate.
• Edits: Modify current photographs utilizing a brand new immediate, both partially or fully.

gpt-image-1 Pricing

Earlier than diving into learn how to use and deploy the mannequin, it’s essential to know the pricing to make sure its efficient and budget-conscious utilization.

The gpt-image-1 mannequin is priced per token, with totally different charges for textual content and picture tokens:

• Textual content enter tokens (prompts): $5 per 1M tokens
• Picture enter tokens (uploaded photographs): $10 per 1M tokens
• Picture output tokens (generated photographs): $40 per 1M tokens

In sensible phrases, this roughly equates to:

• ~$0.02 for a low-quality sq. picture
• ~$0.07 for a medium-quality sq. picture
• ~$0.19 for a high-quality sq. picture

For extra detailed pricing by picture high quality and backbone, consult with the official pricing web page right here.

Observe: This mannequin generates photographs by first creating specialised picture tokens. Due to this fact, each latency and general price depend upon the variety of tokens used. Bigger picture dimensions and better high quality settings require extra tokens, rising each time and price.

gpt-image-1: Arms-on Software

Lastly it’s time to see how we are able to generate photographs utilizing the gpt-image-1 API.

We can be utilizing the picture era endpoint to create photographs primarily based on textual content prompts. By default, the API returns a single picture, however we are able to set the n parameter to generate a number of photographs directly in a single request.

Earlier than operating our essential code, we have to first run the code for set up and establishing the setting.

!pip set up openai
import os
os.environ['OPENAI_API_KEY'] = ""

Producing Photographs Utilizing gpt-image-1

Now, let’s attempt producing a picture utilizing this new mannequin.

Enter Code:

from openai import OpenAI
import base64
shopper = OpenAI()


immediate = """
A serene, peaceable park scene the place people and pleasant robots are having fun with the
day collectively - some are strolling, others are taking part in video games or sitting on benches
beneath bushes. The ambiance is heat and harmonious, with delicate daylight filtering
via the leaves.
"""


end result = shopper.photographs.generate(
    mannequin="gpt-image-1",
    immediate=immediate
)


image_base64 = end result.knowledge[0].b64_json
image_bytes = base64.b64decode(image_base64)


# Save the picture to a file
with open("utter_bliss.png", "wb") as f:
    f.write(image_bytes)

Output:

Modifying Photographs Utilizing gpt-image-1

gpt-image-1 affords quite a lot of picture enhancing choices. The picture edits endpoint lets us:

• Edit current photographs
• Generate new photographs utilizing different photographs as a reference
• Edit components of a picture by importing a picture and masks indicating which areas needs to be changed (a course of referred to as inpainting)

Modifying an Picture Utilizing a Masks

Let’s attempt enhancing a picture utilizing a masks. We’ll add a picture and supply a masks to specify which components of it needs to be edited.

The clear areas of the masks can be changed primarily based on the immediate, whereas the colored areas will stay unchanged.

Now, let me ask the mannequin so as to add Elon Musk to my uploaded picture.

Enter Code:

from openai import OpenAI
shopper = OpenAI()


end result = shopper.photographs.edit(
    mannequin="gpt-image-1",
    picture=open("/content material/analytics_vidhya_1024.png", "rb"),
    masks=open("/content material/mask_alpha_1024.png", "rb"),
    immediate="Elon Musk standing in entrance of Firm Emblem"
)


image_base64 = end result.knowledge[0].b64_json
image_bytes = base64.b64decode(image_base64)


# Save the picture to a file
with open("Elon_AV.png", "wb") as f:
    f.write(image_bytes)

Output:

Factors to notice whereas enhancing a picture utilizing gpt-image-1:

• The picture you need to edit and the corresponding masks should be in the identical format and dimensions, and every needs to be lower than 25MB in dimension.
• The immediate you give can be utilized to explain the whole new picture, not simply the portion being edited.
• In the event you provide a number of enter photographs, the masks can be utilized solely to the primary picture.
• The masks picture should embrace an alpha channel. In the event you’re utilizing a picture enhancing device to create the masks, be certain that it’s saved with an alpha channel enabled.
• When you have a black-and-white picture, you should utilize a program so as to add an alpha channel and convert it into a legitimate masks as offered under:

from PIL import Picture
from io import BytesIO


# 1. Load your black & white masks as a grayscale picture
masks = Picture.open("/content material/analytics_vidhya_masked.jpeg").convert("L")


# 2. Convert it to RGBA so it has house for an alpha channel
mask_rgba = masks.convert("RGBA")


# 3. Then use the masks itself to fill that alpha channel
mask_rgba.putalpha(masks)


# 4. Convert the masks into bytes
buf = BytesIO()
mask_rgba.save(buf, format="PNG")
mask_bytes = buf.getvalue()


# 5. Save the ensuing file
img_path_mask_alpha = "mask_alpha.png"
with open(img_path_mask_alpha, "wb") as f:
    f.write(mask_bytes)

Greatest Practices for Utilizing the Mannequin
