Cheapest AI Image Generators: 5 Budget Models Compared
Get the most images for your money. The 5 most affordable AI image models ranked by value, quality, and features.
You don't need expensive models to generate good AI images. The cheapest AI image generators on Melies range from 2 credits (FLUX Schnell) to 10 credits (Seedream 4.5), meaning you can generate 50 to 250 images per month on the Starter plan alone. The question is which budget model gives you the best quality for the price.
FLUX Schnell and FLUX.2 Klein are the fastest and cheapest options at 2-3 credits, ideal for rapid prototyping and testing prompts. FLUX Dev (5 credits) steps up quality significantly. Seedream v4 Edit (8 credits) adds image editing capabilities, and Seedream 4.5 (10 credits) delivers near-premium quality at a budget price with 4K resolution support.
All 5 models are available on Melies with shared credits. Start with Schnell to iterate on your prompt, then switch to a higher-quality model for the final output.
