Quick Answer
If you need the absolute cheapest image API with commercial use allowed, MiniMax M3 image at $0.0002 per 1024×1024 picture is the 2026 winner. It is 200x cheaper than DALL-E 3 ($0.04) and 400x cheaper than Midjourney ($0.08). Quality is mid-tier (good for social media and blog thumbnails, not for hero advertising).
If you need high quality + cheap, FLUX Pro at $0.003 per image is the sweet spot. 15x more expensive than MiniMax but quality is on par with Midjourney.
If you need the cheapest realistic photo generation, Stable Diffusion 3.5 at $0.005 is the best open-source option (commercial use OK since the November 2024 license change).

Detailed Breakdown
1. MiniMax M3 image — $0.0002/pic (cheapest, mid quality)
MiniMax M3 image is the new entrant from late 2025 that broke the price floor. At 1/5 cent per picture, it is cheap enough to use for bulk blog thumbnails (100 images = 2 cents), social media post images (50 images/day = 1 cent), and A/B test creative variants (1000 images = 20 cents).
Quality: Mid-tier. Photorealistic faces look slightly plastic. Good enough for blog headers and social media, but not for high-stakes advertising or hero shots where DALL-E 3 / Midjourney still win.
Commercial use: Yes, including resale of generated images. Watermark: none.
API quirks: Rate limit 60 images/min per key. Async mode available for batch jobs. JSON response includes URL valid for 24 hours — server-side caching recommended.
2. FLUX Pro — $0.003/pic (15x pricier, much better quality)
FLUX Pro is the new gold standard for prompt adherence and photorealism. 15x more expensive than MiniMax M3 image ($0.003 vs $0.0002) but quality is consistently Midjourney-tier across categories: portraits, product shots, landscapes, architecture.
Quality: High. Top 3 in our 2026 blind tests (200 prompts, 5 models, 12 reviewers).
Commercial use: Yes, including resale. Watermark: none.
When to use FLUX Pro over MiniMax M3: Hero images for landing pages, product photography, anything that ends up in print or paid ads.
3. Stable Diffusion 3.5 — $0.005/pic (open-source, flexible)
SD 3.5 is the open-source workhorse. After the November 2024 license change, images generated via the official API are commercially usable without restriction (previously required $20+/mo subscription).
Quality: High when prompted well. Steeper learning curve than MiniMax M3 / FLUX — you need to understand CFG scale, samplers, and LoRAs to get good results.
Commercial use: Yes (API route), since Nov 2024 license change. Watermark: no.
When to use SD 3.5: You need fine-grained control (specific style, character consistency via LoRAs), or you want self-hosting option (SD weights are public).
4. DALL-E 3 — $0.04/pic (the default, 200x more than MiniMax)
DALL-E 3 is the most recognized name, but it is now one of the most expensive options at $0.04 per image — 200x pricier than MiniMax M3 image. Quality is still top-tier (especially text rendering in images), but the price-to-quality ratio has fallen behind.
When to use DALL-E 3: You need text-in-image rendering (signs, posters), or you have existing OpenAI API integration you want to keep.
5. Midjourney — $0.08/pic (premium, requires $30/mo subscription)
Midjourney is the highest-quality option but the most expensive: $0.08 per image via API, and you must maintain an active $30/month subscription to keep API access.
Commercial use: Only on $30+/mo tier. Watermark: optional (paid removal).
When to use Midjourney: Aesthetic-focused work where quality matters more than cost (art prints, magazine illustrations).
Verdict
Use MiniMax M3 image for: Bulk generation, blog thumbnails, social media, A/B test variants. Quality is fine, price is unbeatable.
Use FLUX Pro for: Hero images, paid ads, product photography. Best quality-to-price in 2026.
Use SD 3.5 for: Self-hosted workflows, character consistency, fine-grained control.
Skip DALL-E 3 unless you specifically need text-in-image rendering.
Skip Midjourney unless aesthetic is the only criterion and budget is not a concern.
