Preços de geradores de imagens IA em 2026: custo por imagem entre Midjourney, DALL·E, Flux, Imagen, Wan, Doubao e mais
Why image generator pricing is harder than it looks
Every image generator advertises a single headline price, but the real cost depends on four variables that change the number by 5–10×:
- Resolution and quality tier — 1024×1024 standard vs. 2048×2048 HD can triple the per-image cost.
- Subscription vs. pay-as-you-go API — a $30/month Midjourney Standard plan works out to about $0.033 per image, while the same prompt on the OpenAI API costs $0.04–$0.13.
- Reject rate — production teams throw away 50–70% of generations. A 60% reject rate means you pay 2.5× the headline price per kept image.
- Hidden credits — Adobe Firefly, Leonardo, and Recraft all meter “premium” features separately, so the actual cost per image is rarely the number on the pricing page.
This guide ranks the 16 most-used text-to-image models in 2026 on a single cost-per-image axis, then translates that into monthly subscription cost for three realistic workloads: 100 images/month (casual), 1,000 images/month (creator), and 10,000 images/month (studio).

Numbers verified against each provider’s public pricing page in July 2026. Midjourney’s per-image cost is the effective rate on a $30/month Standard plan (15 fast GPU hours ≈ 900 images); Mega-plan users drop to ~$0.013 per image.
Chinese models: per-image cost in CNY and USD (Q3 2026)
Chinese models price in RMB (¥) on the domestic platform, but all the major models are now accessible internationally through BytePlus, Alibaba Model Studio (international), fal.ai, PiAPI, 302.AI, OpenRouter, and others. Domestic price is usually 2–3× cheaper than the international route because of the +86 phone-number requirement on Volcano Engine and the CNY-only payment on Baidu Qianfan.
| Model | Provider | Domestic per-image (standard) | Domestic 4K / flagship | International channel per-image | Free tier |
|---|---|---|---|---|---|
| Tongyi Wanxiang wan2.2-t2i-flash | Alibaba Bailian | ¥0.03 (~$0.004) | — | fal.ai $0.008–0.02 | 90 days / 1M tokens |

Subscription pricing for the major Chinese tools (¥/month)
| Tool | Free tier | Entry paid | Mid tier | Top tier | Best for |
|---|---|---|---|---|---|
| Jimeng AI (Dreamina) | Daily free credits (200 trial calls, concurrency 1) | Standard ¥69/mo (auto-renew, ~880 credits) | Advanced ¥200/mo | Premium ¥500/mo | Chinese posters, Doujin / Jianying workflow |
| Jimeng AI credit packs | — | 1K images ¥200; 5K images ¥1,000; 10K images ¥2,000 | 50K images ¥80,000 | 100K images ¥180,000 | API integration + high concurrency |
| Wenxin Yige (Baidu) | Daily free credits (watermarked) | Monthly membership from ¥30/mo | Premium ¥60+/mo | Commercial license pack | Chinese creatives, e-commerce templates |
| Baidu Qianfan ERNIE image API | Free tokens for new Qianfan users | Tiered per-token (¥0.004 input / ¥0.016 output per 1K) | Volume packs | Enterprise contract | Custom development, cross-modal |
| Tencent Hunyuan (API + console) | 10K free images (one-time activation) | 1K images ¥99; 10K images ¥850 | 100K images ¥7,500 | 1M images ¥65,000 | Posters, e-commerce images, product images |
| Tongyi Wanxiang (Alibaba Bailian) | 90 days / 1M free tokens for new users | Per-image ¥0.03–0.20 | Volume packs (e.g. ¥200/5K) | Coding Plan ¥9.9 first month | Alibaba ecosystem, Qwen Studio |
| Zhipu BigModel (CogView) | CogView-3-Flash fully free, concurrency 30 | GLM-4-Air ¥1/1M tokens | GLM-5 ¥30 input / ¥90 output per 1M tokens | GLM-5.1 ¥6/¥24; Coding Plan free | CJK-prompt friendly, large free quota |
| Moonshot Kimi K2.5 | Kimi App free quota | Kimi Coding Plan (subscription) | Kimi multimodal ¥2/¥10 per 1M tokens | Enterprise contract | Long text + multimodal image |
| Doubao Pro (launched 2026-06-23) | Doubao App free | Standard ¥68/mo (auto-renew, includes 2.1 Pro) | Enhanced ¥200/mo (4× quota) | Premium ¥500/mo (10× quota) | All-in-one (text + image + video + digital human) |
A few Chinese subscription details that differ sharply from global services:
- Jimeng AI runs a dual membership + credit system. The ¥69/mo Standard plan comes with ~880 credits per month, which translates to roughly 4,000 standard images or 200 high-quality images — but expect queues during peak hours (tens of thousands of users waiting, 2–11 hour delays are common).
- Doubao launched the new “Pro” tier in June 2026, which bundles Doubao 2.1 Pro + office tasks + digital human + video + Skills into one ¥68/mo package. For agent-style all-stack users, this is better value than buying ChatGPT Plus alone.
- Baidu Qianfan markets ERNIE 4.5 / X1 text-to-image at ¥0.004 / ¥0.016 per 1K tokens, advertised as “1% of GPT-4.5 price.” Converted to per-image, that ends up 2–3× cheaper than GPT Image 1.5 Medium.
- Tencent Hunyuan’s 10K free image pack is a one-time gift. The pack does not auto-roll into pay-as-you-go when exhausted — you must manually enable postpaid billing. This is the most common gotcha for new users.
- Zhipu is the most aggressive on the free tier — CogView-3-Flash is completely free with concurrency 30, and GLM-4.7-Flash is also free, making it the best entry point for individual developers.
Cost by workload
100 images/month (casual creator, blog illustrations)
For a one-image-per-day workflow, the cheapest option is Microsoft Designer (free, 15 fast + unlimited standard per day, no watermark). Among paid tools, the rankings are:
- Midjourney Basic — $10/mo, ~200 fast images. Effectively free overage if you stay under 200.
- ChatGPT Plus — $20/mo, soft daily cap on GPT Image 1.5. Best if you also use ChatGPT for writing.
- Recraft Basic annual — ~$10/mo. Best if you need SVG vector output.
- Ideogram Plus — $8/mo. Best if you need typography.
1,000 images/month (full-time creator, social media)
At 1,000 images per month, the per-image economics start to matter:
- Midjourney Standard — $30/mo, unlimited Relax mode + 15 fast hours. Effective rate ~$0.033/image.
- FLUX.1.1 Pro API — $0.04 × 1,000 = $40/mo, no subscription commitment.
- Imagen 4 standard API — $0.04 × 1,000 = $40/mo, best photorealism for the price.
- Adobe Firefly Standard — $9.99/mo, 2,000 premium credits. Unlimited standard generations. Bundled free with most Creative Cloud plans.
- Recraft Pro annual — ~$16/mo, 2,000 credits. Vector + image.
- China pick: Tongyi Wanxiang wan2.2-t2i-flash API — ¥0.03 × 1,000 = ¥30/mo (~$4.20), roughly 1/10 the price of comparable international models.
- China pick: Tencent Hunyuan 2.0 — ¥0.10 × 1,000 = ¥100/mo (~$14), CJK-prompt friendly with native Chinese aesthetics.
- China multimodal: Doubao Pro ¥68/mo — includes 2.1 Pro text + Seedream image + Seedance video. Quota is 5× the free tier, equivalent to 1,000–2,000 images.
10,000 images/month (studio, e-commerce, agency)
At this scale, subscription tiers stop being the cheapest path and APIs win on raw cost:
- Self-hosted Stable Diffusion 3.5 on an L40S GPU — ~$0.0008/image at full utilization, about $8/month in compute. Requires ML ops.
- FLUX.1 Schnell API — $0.003 × 10,000 = $30/mo at draft quality.
- FLUX.1.1 Pro API — $0.04 × 10,000 = $400/mo, production-grade quality.
- Imagen 4 Fast — $0.02 × 10,000 = $200/mo. Best photorealism per dollar at scale.
- Midjourney Pro — $60/mo, 30 fast hrs + unlimited Relax. The most cost-effective unlimited plan if your prompts don’t need fast-mode priority.
- China self-host: Tongyi Wanxiang wan2.2-t2i-flash — ¥0.03 × 10,000 = ¥300/mo (~$42), 1/10 of international pricing.
- China at scale: Doubao Seedream 5.0 Lite Volcano API — ¥0.22 × 10,000 = ¥2,200/mo (~$310), on par with Imagen 4 Fast.
- China compliance pick: Tencent Hunyuan 100K image resource pack — ¥7,500/mo (~$1,050), includes Chinese aesthetics and East-Asian style specialization, low IP risk.
- China free ceiling: Zhipu CogView-3-Flash — completely free. Run at concurrency 30 and you can hit 1–2M images/month at zero cost.
The hidden costs the headline prices miss
1. Regeneration tax. A 60% reject rate means you pay 2.5× the headline cost per kept image. Drop your reject rate from 60% to 40% with better prompts and reference images, and your monthly bill drops by ~35% even though the per-image price is unchanged.
2. Premium credit metering. Adobe Firefly, Leonardo, and Recraft all bundle “unlimited” standard generations but meter premium features (vector export, video, partner models) against a credit pool. The Firefly Free tier gives you 25 credits and the Standard plan gives 2,000 — a single Character Reference in Ideogram can cost 2–3× the base rate.
3. Resolution multiplier. Stable Diffusion 3.5 Large is $0.065 at 1MP but $0.08 at 2MP. GPT Image 1.5 high-quality is $0.133 at 1024×1024 and $0.20 at portrait/landscape. If your layout allows square crops, save 30–50%.
4. Stealth and private mode. Midjourney Pro ($60/mo) is the cheapest plan with Stealth Mode (private images, no public gallery). Adobe Firefly and Recraft gate privacy to paid tiers as well. If you generate client work, plan on the mid-tier subscription rather than the entry tier.
5. API rate limits. Free-tier API keys on OpenAI, Stability, and Google are throttled to 5–10 requests/minute. Production traffic needs a paid account and may need to be routed through multiple providers.
6. China-specific gotchas. On Volcano Engine, a +86 phone number is required for signup and the account is CNY-only. The Doubao “credit” unit (a Volcano Engine metering unit called “suan-dian” in Chinese, roughly 1 credit = ¥0.01) means 22 credits ≈ ¥0.22/image. Jimeng AI queues 2–11 hours during peak hours. Wenxin Yige watermarks all free-tier outputs.
By use case: which model wins in 2026
- Photorealism and product photography → Midjourney v7 for the look, FLUX.1.1 Pro Ultra ($0.06/image) for API. Imagen 4 Ultra ($0.06) is the best photorealism per dollar if you don’t need Midjourney’s art-direction controls.
- Typography and posters → Ideogram 4.0 is the only Western model that renders readable in-image text more than 70% of the time. For CJK, Seedream 4.5/5.0 Pro (¥0.25–1.36) renders Chinese, Japanese, and Korean with native-quality typography.
- Vector and brand icons → Recraft V3 is the only major Western model with native SVG export, critical for logo and icon work.
- Commercial-safe enterprise → Adobe Firefly is the only major model trained exclusively on licensed content. The $9.99 Standard plan is bundled free with most Creative Cloud subscriptions. In China, ERNIE 4.5/X1 via Baidu Qianfan and Hunyuan 3.0 are the enterprise-grade commercial-safe options.
- Cheapest at scale → FLUX.1 Schnell at $0.003/image for drafts, Imagen 4 Fast at $0.02 for production photorealism. In China, Tongyi Wanxiang wan2.2-t2i-flash at ¥0.03/image (~$0.004) is the cheapest API.
- Self-hosted, free, fully customizable → Stable Diffusion 3.5 weights on Hugging Face, free commercial license for organizations under $1M annual revenue. In China, Qwen-Image-3.0 and CogView-4 are also open-weight and self-hostable.
- Open-chat editing and brand consistency → GPT Image 1.5 in ChatGPT Plus, $20/month. The best in-conversation “change this, keep that” workflow. The Chinese equivalent is Doubao 2.1 Pro in the new ¥68/month Pro tier.
- Best free option → Microsoft Designer for casual use, Leonardo AI for self-serve experimentation with custom LoRAs. In China, Zhipu CogView-3-Flash (free, concurrency 30) is the strongest free option, followed by Hunyuan-lite.
- Chinese prompts and East-Asian aesthetics → Seedream 4.5/5.0 Pro (Volcano Engine) for multi-reference and Chinese typography, Tongyi Wanxiang wan2.5/2.6 for the “Oriental photorealism” look, Tencent Hunyuan 3.0 for high-end Chinese cultural and traditional aesthetics, Wenxin Yige for e-commerce and Chinese marketing templates.
How to pick
Pick the tool that matches the single use case you spend most of your time on. Multi-assistant workflows are common in 2026 — even power users tend to default to Midjourney for client work, GPT Image 1.5 for quick social media, and FLUX or Stable Diffusion for fully-customized production pipelines.
If you only pay for one subscription, Midjourney Standard at $30/month is still the best value for visual quality in 2026. The output, the v7 art-direction controls, and the new Omni Reference feature (for character consistency) are unmatched at that price.
If you specifically need API access at scale, FLUX.1.1 Pro at $0.04 per image or Imagen 4 at $0.04 per image are the best mid-tier production options.
For typography-led posters and logos, Ideogram 4.0 at $0.06/image (or $8/month for the Plus plan) is the clear winner — no other model produces readable in-image text consistently.
For fully-customizable, open-source workflows, FLUX.1 Dev and Stable Diffusion 3.5 (self-hosted) are the best options, but be prepared to invest GPU hours and developer time in setup.
For commercial safety at the lowest risk, Adobe Firefly Standard at $9.99/month is the cleanest answer — and it’s already included with most Creative Cloud subscriptions. In China, Baidu Qianfan ERNIE 4.5/X1 is the most enterprise-friendly, with full Chinese regulatory compliance and a published “1% of GPT-4.5 price” rate card.
For the single best China-only subscription, Doubao Pro at ¥68/month is the strongest all-in-one bundle in 2026 — text, image, video, digital human, and Skills in one subscription. For free, Zhipu CogView-3-Flash is the ceiling.
Quick reference: cheapest API per image, by use case
If you just want the cheapest way to call a model, here is the answer in two lines per region:
- Global cheapest — Flux.1 Schnell ($0.003) for drafts, FLUX.1.1 Pro ($0.04) for production photorealism, Ideogram 3.0 Turbo ($0.03) for typography.
- China cheapest — Tongyi Wanxiang wan2.2-t2i-flash (¥0.03) for drafts, Doubao Seedream 5.0 Lite (¥0.22) for production, Hunyuan 2.0 (¥0.10) for Chinese aesthetics, CogView-4 (¥0.05) for everything else. All have free trial credits.
- Free with the least friction — Zhipu CogView-3-Flash (China, free) or Microsoft Designer (global, 15 fast + unlimited standard per day).

Perguntas frequentes
Qual gerador de imagens IA é o mais barato por imagem em 2026?
Entre as APIs comerciais, o Flux.1 Schnell é o mais barato a aproximadamente US$ 0,003 por imagem, seguido pelo GPT Image 1 Mini a US$ 0,005 (qualidade baixa, 1024×1024) e o Imagen 4 Fast a US$ 0,02. Se você hospedar o Stable Diffusion XL na sua própria GPU, o custo total cai para cerca de US$ 0,0008 por imagem em plena utilização — mas você paga pelo hardware antecipadamente.
Midjourney é mais barato que DALL·E quando você realmente usa?
Por imagem, sim. O Midjourney Standard a US$ 30/mês entrega cerca de 900 imagens rápidas, o que dá cerca de US$ 0,033 por imagem. O mesmo prompt via DALL·E 3 (agora GPT Image 1.5) custa de US$ 0,034 a US$ 0,133 por imagem. O porém: Midjourney não tem API pública nem plano gratuito, enquanto a OpenAI oferece um nível gratuito do ChatGPT com algumas imagens por dia e uma assinatura Plus de US$ 20/mês.
Qual é o melhor gerador de imagens IA gratuito em 2026?
A custo zero, o Microsoft Designer (antigo Bing Image Creator) é a melhor opção gratuita em 2026 — oferece 15 gerações rápidas por dia mais imagens padrão ilimitadas, sem marca d'água. O nível gratuito do Leonardo AI oferece 150 créditos diários (~25 imagens padrão) e é a melhor opção para experimentação autônoma. Para código aberto totalmente livre, o Stable Diffusion 3.5 é gratuito se você tiver uma GPU de 16 GB ou mais.
Quanto custa a geração de imagens no ChatGPT Plus?
O ChatGPT Plus custa US$ 20/mês fixos e inclui a geração com GPT Image 1.5 com um limite diário flexível. Se você exceder o limite, espera ou faz upgrade para o ChatGPT Pro a US$ 200/mês, que oferece geração ilimitada na qualidade máxima. Por dentro, o mesmo modelo na API da OpenAI custa de US$ 0,009 (baixa) a US$ 0,133 (alta) por imagem de 1024×1024.

Em assinatura, o Midjourney Mega (US$ 120/mês) e o Adobe Firefly Premium (US$ 199,99/mês) são os mais caros.
O Adobe Firefly vale a pena em comparação com ferramentas gratuitas?
Se você se importa com segurança comercial, sim. O Firefly é o único modelo importante treinado exclusivamente com conteúdo licenciado do Adobe Stock, então o risco de PI para uso corporativo é o mais baixo da categoria. O plano Standard de US$ 9,99/mês dá 2.000 créditos premium e gerações padrão ilimitadas, e o Firefly vem incluído gratuitamente na maioria das assinaturas do Creative Cloud.
Qual gerador chinês de imagens IA é o mais barato por imagem?
O Tongyi Wanxiang 2.2-t2i-flash é o mais barato a ¥0,03/imagem (cerca de US$ 0,004) via Alibaba Bailian, seguido de perto pelo Qwen-Image-Max a cerca de US$ 0,08/imagem na BytePlus e 302.AI. O nível Express do Tencent Hunyuan custa ¥0,06–0,08/imagem, o Doubao Seedream 4.5/5.0 Lite custa ¥0,22–0,25/imagem, e o Wenxin Yige é gratuito com créditos diários com planos pagos a partir de ¥30/mês. Para opções totalmente gratuitas, o Zhipu CogView-3-Flash é gratuito no BigModel.
Quanto custa o Doubao Seedream via Volcano Engine comparado aos revendedores internacionais?
Pelo Volcano Engine (China continental, exige telefone +86): Seedream 5.0 Lite são 22 créditos/imagem (~¥0,22) e Seedream 4.5 são 25 créditos/imagem (~¥0,25) para saída 1K/2K; a saída 4K do Seedream 4.5 escala linearmente. Pelos revendedores internacionais (fal.ai, PiAPI, BytePlus ModelArk, 302.AI): Seedream 5.0 Pro custa US$ 0,0675/imagem a ≤1536² e US$ 0,135/imagem a ≤2048². Portanto, a rota internacional é cerca de 2,5 a 3 vezes o preço interno em CNY, mas é a única opção para desenvolvedores não chineses.
Como o preço do Wenxin Yige (imagem ERNIE) se compara ao da API da OpenAI?
O Wenxin Yige (o produto de consumo) começa grátis com créditos diários, com assinatura paga a partir de ¥30/mês. Para a API ERNIE-image subjacente no Baidu Qianfan, a tabela oficial gira em torno de ¥0,004/1K tokens de entrada e ¥0,016/1K tokens de saída, mais alguns centavos por imagem em 1024×1024. Em comparação, o GPT Image 1.5 Medium da OpenAI custa US$ 0,034/imagem — depois de converter a tarifa por token em tarifa por imagem, a API do Baidu fica 2 a 3 vezes mais barata em qualidade padrão e bem mais barata em alta qualidade (onde a OpenAI chega a US$ 0,133/imagem).
Posso obter geração de imagens chinesa gratuita em 2026?
Sim, há quatro opções críveis. (1) O Zhipu CogView-3-Flash é totalmente gratuito no BigModel com limite de concorrência de 30. (2) O Wenxin Yige oferece uma cota diária de créditos gratuitos (com marca d'água). (3) O Volcano Engine oferece 200 chamadas de teste gratuitas (concorrência 1) para geração com Jimeng. (4) Hunyuan-lite é gratuito no Tencent Cloud para o modelo de texto e barato a ¥0,06–0,08/imagem para imagem. Internacionalmente, fal.ai, PiAPI e 302.AI também oferecem créditos de teste gratuitos no cadastro.
O Zhipu CogView-4 é mais barato que o Recraft para imagens em estilo vetorial?
O Zhipu CogView-4 custa ¥0,05/imagem (~US$ 0,007) por geração, enquanto o Recraft custa US$ 0,04/imagem (¥0,29) na API pública. Portanto, o Zhipu é cerca de 4 a 5 vezes mais barato no preço de tabela. No entanto, o Recraft é o único modelo importante com exportação SVG nativa — para imagens puramente raster, o Zhipu vence no preço; para saída vetorial, o Recraft é a única opção crível independentemente do custo.
