Quick Comparison: Image Generation API Pricing
Seven contenders. Cheapest hosted: Flux Schnell at $0.003/img. Mid-tier: DALL-E 3, Flux Pro, SD3.5 ($0.03-$0.05). Premium: GPT Image 1.5 HD ($0.19), Midjourney Turbo ($0.15). Speed leaders: SD3.5 + Flux Pro (2-8s).
| Model | Price per image | Resolution options | Speed | Quality |
|---|---|---|---|---|
| DALL-E 3 Standard | $0.04-$0.08 | 1024x1024, 1024x1792, 1792x1024 | 8-15s | High |
| DALL-E 3 HD | $0.08-$0.12 | 1024x1024, 1024x1792, 1792x1024 | 12-20s | Very High |
| GPT Image 1.5 | $0.03-$0.19 | Up to 2048x2048 | 10-25s | Very High |
| Flux Pro 1.1 | $0.04-$0.06 | Up to 2048x2048 | 3-8s | Very High |
| Flux Dev | $0.025-$0.03 | Up to 2048x2048 | 5-12s | High |
| SD3.5 (via API) | $0.03-$0.05 | Up to 2048x2048 | 2-6s | High |
| Midjourney API | $0.01-$0.10 | Up to 2048x2048 | 15-60s | Highest |
DALL-E 3 Pricing Breakdown by Resolution and Quality
Six price points: 1024² Standard $0.04, 1024² HD $0.08, portrait/landscape $0.08 Standard / $0.12 HD. Square Standard is the value pick — portrait costs 2x. DALL-E 2 still available at $0.02 for legacy use.
DALL-E 3 pricing through the OpenAI API depends on two variables: image size and quality setting.
DALL-E 3 pricing matrix:
| Quality | 1024x1024 | 1024x1792 | 1792x1024 |
|---|---|---|---|
| Standard | $0.040 | $0.080 | $0.080 |
| HD | $0.080 | $0.120 | $0.120 |
DALL-E 2 (still available):
| Resolution | Price per image |
|---|---|
| 1024x1024 | $0.020 |
| 512x512 | $0.018 |
| 256x256 | $0.016 |
Key observations from this pricing structure:
Going from Standard to HD doubles the cost but does not double the quality. HD mode adds finer detail, better textures, and more consistent lighting. For social media graphics and blog illustrations, Standard quality is sufficient. HD is worth it for product mockups, hero images, and print-quality output.
Portrait and landscape orientations (1024x1792 and 1792x1024) cost 2x the square format at Standard quality and 1.5x at HD. If your use case allows square images, you save significantly.
DALL-E 2 remains available at $0.02 per image for 1024x1024. Quality is noticeably lower than DALL-E 3, but for bulk generation of simple graphics, placeholders, or variations, it can be cost-effective.
GPT Image 1.5: OpenAI's Next-Generation Model
Token-based pricing: ~$0.03 (low res standard) to ~$0.19 (2048² high). Native GPT-5.4 integration brings conversation context, native image editing/inpainting, far better text rendering than DALL-E 3. Slower (10-25s).
GPT Image 1.5 (also referred to as gpt-image-1.5 in the API) represents OpenAI's latest image generation model, integrated natively with GPT-5.4. Pricing is based on input and output tokens rather than flat per-image rates.
GPT Image 1.5 estimated per-image cost:
| Quality | Low res (512x512) | Medium res (1024x1024) | High res (2048x2048) |
|---|---|---|---|
| Standard | ~$0.03 | ~$0.05 | ~$0.11 |
| High | ~$0.05 | ~$0.09 | ~$0.19 |
The token-based pricing makes exact costs variable depending on the complexity of your prompt. Longer, more detailed prompts consume more input tokens. Image output cost is determined by resolution and quality level.
What makes GPT Image 1.5 different:
- Native integration with GPT-5.4 means the model understands context from conversation
- Text rendering in images is significantly better than DALL-E 3
- Supports image editing and inpainting natively
- Can generate images with precise layout control
- Handles multi-subject compositions more accurately
Trade-offs:
- Token-based pricing is less predictable than DALL-E 3's flat rates
- High-resolution outputs at high quality approach $0.19 per image, making it the most expensive OpenAI option
- Slower generation compared to DALL-E 3 (10-25 seconds typical)
- Still behind Midjourney on photorealistic human rendering
TokenMix.ai pricing data shows that for high-volume users, GPT Image 1.5 at standard quality and medium resolution ($0.05/image) offers better quality per dollar than DALL-E 3 Standard ($0.04/image).
How DALL-E API Billing Works
Per-request billing, not per-token (DALL-E 3). Failed requests don't bill. No batch API discount. Rate limits: 7 imgs/min DALL-E 3, 5/min GPT Image 1.5. GPT Image 1.5 alone uses token-based billing.
OpenAI bills image generation per request, not per token. Each API call that returns an image counts as one billable event regardless of prompt length.
Important billing details:
- Failed requests (errors, content policy rejections) are not billed
- Image variations and edits (DALL-E 2 only) are billed at the same rate as generations
- There is no batch API discount for image generation
- Rate limits: 7 images per minute for DALL-E 3, 5 per minute for GPT Image
- GPT Image 1.5 uses token-based billing, where both the text prompt and generated image consume tokens
Cost optimization tips:
- Use 1024x1024 Standard quality when possible (saves 50-67% vs. HD portrait)
- Generate at lower resolution and upscale with a separate tool if final output needs to be large
- Use DALL-E 2 for placeholder and draft images during iteration
- Batch your prompts efficiently since rate limits are per-minute
For teams generating images at scale, TokenMix.ai provides cost tracking across image generation APIs, helping identify which model and resolution combination gives the best results per dollar.
Flux Pro and Flux Dev: The Open-Source Challenger

- No native conversation context integration like GPT Image 1.5
Best for: Teams that need high-quality image generation with better text rendering and faster speed at comparable or lower cost to DALL-E 3. Self-hosting Flux Dev can reduce costs below $0.01 per image for high-volume users.
Stable Diffusion API Options
Hosted: Stability AI $0.03-$0.05, Replicate $0.01-$0.03, Together AI $0.01-$0.02. Self-hosted on A100 80GB: $0.003-$0.005/image at 400-600 imgs/hour. Cheapest path at scale.
Stable Diffusion offers the most flexible pricing since the models are open-source. You can self-host for compute costs only, or use hosted API providers.
Hosted API pricing (SD3.5, SDXL):
| Provider | SD3.5 per image | SDXL per image | Notes |
|---|---|---|---|
| Stability AI | $0.03-$0.05 | $0.02-$0.04 | Official API |
| Replicate | $0.03 | $0.01 | Pay per compute second |
| Together AI | $0.02 | $0.01 | Volume discounts available |
Self-hosted costs (approximate):

|---|---|---|---|
| A100 (80GB) | 400-600 | $0.003-$0.005 | Cloud rental ~$2/hr |
| A10G | 150-250 | $0.004-$0.007 | Cheaper GPU, slower |
| RTX 4090 | 200-350 | $0.002-$0.004 | On-premise, power only |
Best for: Maximum flexibility and minimum cost at scale. If you generate 10,000+ images per month and have engineering capacity to manage infrastructure, self-hosted Stable Diffusion is the cheapest option by a wide margin. For API use, Stability AI and Replicate offer competitive hosted alternatives.
Midjourney API: The Enterprise Option
Three speeds: Fast $0.05-$0.10 (15-30s), Relaxed $0.01-$0.02 (30-60s), Turbo $0.10-$0.15 (10-20s). Highest aesthetic quality (MOS 9.5). Rate-limited and slow, so impractical for bulk generation.
Midjourney launched its official API in 2025, bringing its industry-leading image quality to programmatic use. Pricing is credit-based.
Midjourney API pricing:
| Speed | Cost per image | Generation time |
|---|---|---|
| Fast | ~$0.05-$0.10 | 15-30s |
| Relaxed | ~$0.01-$0.02 | 30-60s |
| Turbo | ~$0.10-$0.15 | 10-20s |
Best for: Teams where image quality is the absolute priority, particularly for marketing, advertising, and creative content. Midjourney consistently leads on aesthetic quality for photorealistic and artistic images, but the pricing and rate limits make it less practical for bulk generation.

What's the Bottom Line on DALL-E Pricing?
DALL-E is no longer best value. Default to Flux Pro 1.1 for quality-focused generation, DALL-E 3 for OpenAI-stack simplicity, self-hosted Flux Dev / SD for high-volume batch. Match model to job, not loyalty.
DALL-E API pricing is straightforward -- $0.04 to $0.12 per image -- but it is no longer the best value in 2026. Flux Pro 1.1 matches DALL-E 3 quality at comparable price with faster generation and better text rendering. GPT Image 1.5 makes sense when you need LLM-integrated image generation despite higher costs at premium settings. Self-hosted Stable Diffusion and Flux Dev dominate on cost at high volumes.
For most developers, the practical recommendation is: use Flux Pro 1.1 for quality-focused generation, DALL-E 3 for simplicity within the OpenAI ecosystem, and self-hosted open-source for high-volume batch processing.
