Session history
01 · Overview
What is HY Image 3.5 Preview?
HY Image 3.5 is the latest Hunyuan image model from Tencent, currently in preview — which means the quality is already strong and the price is deliberately low while the model is being tuned. It renders clean, well-lit scenes with a photographic bent.
The pricing is the story: 1K and 2K cost the same 4 credits, and the 4K tier is only 5. Edits cost the same as generations at every tier, and references are free — attach up to five without changing the price. New accounts start with 20 free credits: five images at any tier.
Specs & capabilities
| Inputs | Text to image · Image editing · Multi-reference (up to 5 in the studio) |
| Resolution | 1K, 2K or 4K tiers |
| Aspect ratios | 10 ratios in the studio, up to 21:9 ultrawide |
| Output formats | PNG |
| Pricing shape | Flat per image upstream: 1K/2K $0.0192, 4K $0.0256 — priced here at 4, 4 and 5 credits. References are never charged. |
Good to know: this is a preview model — quality, limits and behaviour may change as Tencent tunes it. The 2K tier costs the same as 1K, so there is rarely a reason to render at 1K unless you need the file small.

Prompt guide
- Always take the 2K: it costs the same 4 credits as 1K — the only reason to render at 1K is a smaller file.
- Use references freely: HY never charges for them, so composite from five photos without watching the meter.
- 4K for finals: at 5 credits, HY's 4K tier is the cheapest large-format render on Pizyn — use it for prints and hero images.
- Preview means moving: quality and behaviour may shift as Tencent tunes the model; if a render surprises you, re-run it — the model may have moved.

06 · FAQ
HY Image 3.5 Preview FAQ
How much does HY Image 3.5 Preview cost?
4 credits ($0.04) at 1K and 2K, 5 credits ($0.05) at 4K — for generation and edits alike. Reference images are never charged, however many you attach (up to five).
What is HY Image 3.5 Preview?
HY Image 3.5 is Tencent's Hunyuan image model, currently in preview and served on Pizyn via APImart. Preview means the model is still being tuned — quality and behaviour may change.
Why does 2K cost the same as 1K?
That is the upstream pricing: both tiers are $0.0192 per image. Pizyn passes that through, so the 2K tier is effectively a free upgrade over 1K.
Are reference images really free?
Yes. HY bills each output image once, whatever you pass in — up to five references ride along at no extra charge, in both generation and edit modes.
How long does a generation take?
Typically under a minute for 1K and 2K; the 4K tier can take a little longer.
When should I use a different model?
For the cheapest renders overall (Muse Image at 1 credit), the most references (GPT Image 2.5 takes 16), or a stable non-preview flagship (Seedream 5 Pro).
