Best Chinese AI Image Generation Models 2026: Seedream vs Hunyuan vs Vidu vs Qwen-Image

Image generation is where Chinese AI pricing is most aggressive in 2026: a finished 1K-resolution image now costs cents, reference-conditioned generation (product shots, character consistency, style transfer) ships as a first-class API feature, and free tiers exist for prototyping. This guide compares the major Chinese image models on the numbers API buyers care about: cost per image, reference-image support, resolution ceiling, and where each model genuinely wins.

The image lineup at a glance (Sep 2026)

"From" prices vary with resolution and reference-image count; all rates are NovAI list prices (provider price, zero platform fee) as of September 2026.

What images actually cost at scale

For context: at $0.027 per image, a full A/B test of 100 ad creatives costs $2.70. Failed generations on NovAI are auto-refunded, so errored jobs never consume your balance.

Seedream 5.0: the default production pick

ByteDance's Seedream line set the 2026 price floor for flagship-quality images. doubao-seedream-5.0 at $0.027/image is the workhorse; 5.0-pro at $0.034 adds fine-detail and prompt-adherence improvements worth the premium for hero assets. Two additional Seedream routes (v5.0-lite ~$0.034 and v5.0-pro from ~$0.046) expose more resolution and reference options — check the model marketplace for the live spec matrix.

Vidu Image Q2: the reference-image specialist

Shengshu's vidu-image-q2 is the standout for consistency work: it accepts up to 7 reference images per request and outputs from 1080p up to 4K. That makes it the natural choice for character sheets, brand-consistent campaigns, and style-locked product photography — workflows where re-rolling a generic model wastes more money than the reference route costs. Pricing starts around $0.029/image and scales with resolution and reference count.

Hunyuan Image V3 & the Wan family

Tencent's hy-image-v3 (~$0.031) is a strong generalist with particularly good photorealism. Alibaba's Wan (Vega) family spans three tiers — lite from ~$0.025, flash from ~$0.069, pro from ~$0.146 — letting you match spend to asset importance within one vendor.

CogView-3-Flash & Qwen-Image: free tier and the ecosystem

Zhipu's cogview-3-flash is free and unlimited on NovAI — the right tool for prompt engineering and layout experiments before committing budget to a paid model. Alibaba's Qwen-Image, meanwhile, earned attention for rendering Chinese and English text inside images more reliably than almost anything else; it is not yet callable via NovAI, and this page will be updated when that changes.

Calling Chinese image models from anywhere

Image endpoints on NovAI follow the OpenAI images-style pattern: one POST, an image URL (or base64) back. No Chinese phone number, no Alipay, no CNY billing.

# Generate an image (Seedream 5.0)
curl https://aiapi-pro.com/v1/images/generations \
  -H "Authorization: Bearer sk-novai-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "doubao-seedream-5.0",
    "prompt": "Minimalist product photo of a ceramic tea set on walnut wood, soft morning light",
    "size": "1024x1024"
  }'

# -> returns an image URL you can hotlink or download.
# Failed generations are auto-refunded.

Parameter names and reference-image fields differ slightly per model family; exact schemas are in the API docs, and you can generate your first image in the browser via AI Studio before writing any code.
