How to Use Each Text-to-Image API
Flux 2 via Hypereal AI (Fastest & Cheapest)
Flux 2 is the current performance leader — sub-second generation at the lowest price.
import hypereal
client = hypereal.Client(api_key="YOUR_API_KEY")
result = client.generate_image(
model="flux-2",
prompt="a minimalist logo for a coffee shop, vector art, white background",
width=1024,
height=1024,
num_images=4
)
for image in result.images:
print(image.url)
Best for: Fast prototyping, high-volume generation, any style.
DALL-E 4 via OpenAI
from openai import OpenAI
client = OpenAI(api_key="YOUR_API_KEY")
response = client.images.generate(
model="dall-e-4",
prompt="a minimalist logo for a coffee shop, vector art, white background",
size="1024x1024",
n=1
)
print(response.data[0].url)
Best for: Highest fidelity when cost isn't a concern.
Stable Diffusion 3.5 via Stability AI
import requests
response = requests.post(
"https://api.stability.ai/v2/generation/stable-diffusion-3.5",
headers={"Authorization": f"Bearer YOUR_API_KEY"},
json={
"prompt": "a minimalist logo for a coffee shop, vector art, white background",
"width": 1024,
"height": 1024
}
)
Best for: Open-source ecosystem, LoRA customization.
SeeDream 4.0 via Hypereal AI
result = client.generate_image(
model="seedream-4",
prompt="a minimalist logo for a coffee shop, vector art, white background",
width=1024,
height=1024
)
Best for: Photorealism, controlled generation with reference images.

How to Choose the Right Text-to-Image API
Ask yourself these questions:
- How many images per month? — If >10K, pricing becomes critical. Hypereal/Flux is 40x cheaper than DALL-E.
- How fast do you need results? — For real-time UIs, sub-second matters. Only Flux delivers that.
- Do you need consistency? — For brand assets, use models with seed/reference image support.
- Content restrictions? — OpenAI and Google block many content types. Hypereal has no restrictions.
- Custom models? — If you need fine-tuned/LoRA models, Stable Diffusion or Flux are your best options.
Best Practices for Text-to-Image APIs
- Be specific in prompts — "a red leather handbag on a marble table, studio lighting, product photography" beats "a handbag"
- Use negative prompts — specify what you don't want: "no text, no watermark, no blurry"
- Generate multiple variants — request 4 images and pick the best one
- Set consistent seeds — for reproducible results, fix the random seed
- Match resolution to use case — 512x512 for thumbnails, 1024x1024 for product images, 2048x2048 for print
