AIREITERHy Image 3.5 Preview is worth a low-cost API pilot, not an unconditional production switch: Tencent documents the model and multi-turn editing, but the cited price is for 2K output while 4K pricing and preview stability remain unclear.
Hy Image 3.5 Preview API: the answer in one table
| Question | Current answer |
|---|---|
| Is it available? | Yes, as Tencent Cloud model hy-image-v3.5-preview |
| Main modes | Text-to-image, image-to-image, reference-image editing, multi-turn editing |
| References | Up to five are described in launch material |
| Price | ¥0.15 per reported 2K output image; Tencent's official announcement lists $0.024 internationally |
| Resolution | Launch coverage says 2K; TokenHub documentation describes up to 4,096 × 4,096 |
| Billing caveat | The cited prices are headline 2K rates; verify regional and 4K pricing before volume use |
| Recommendation | Pilot the editing workflow; do not treat preview claims as an SLA |
What Tencent officially exposes
The TokenHub documentation describes text and image inputs, image-to-image generation, and multi-turn editing with prior context supplied to the next request.
Launch coverage describes up to five reference images and multiple aspect ratios; Tencent Cloud documentation covers the API response behavior.
One specification needs careful handling. Launch reporting commonly says “up to 2K,” while the current Tencent Cloud documentation describes output dimensions up to 4,096 × 4,096. Treat the API documentation as the implementation reference, but verify the allowed size and price for your account and region before assuming that every 4K request costs the 2K headline rate.
The practical use case is a revision loop
Hy Image 3.5 Preview is most interesting when the job is not “make one attractive image.” A useful workflow is:
- Send a prompt and one or more reference images.
- Store the generated image and retain the prior image or context required for the next edit request.
- Ask for a targeted change, such as a different product color or a revised poster headline.
- Send the required prior image and history with the next instruction.
- Check whether the subject, layout, and text survive the edit before accepting the output.
It is best suited to posters, product graphics, storyboards, and other workflows that benefit from continuity. The workflow still needs an application-side acceptance check because Preview access does not establish stable latency, unlimited context, consistent character identity, or a guaranteed success rate across edit rounds.
Hy Image 3.5 Preview pricing: cheap enough to pilot
Tencent launch coverage reports ¥0.15 for a generated 2K image in China. The official Tencent announcement gives an international headline price of $0.024 per image and says reference images are not charged. At that rate, 1,000 successful 2K images would be $24 before taxes, account-level charges, or provider markups. The article does not establish the price for 4K output.
| Cost scenario | Simple headline calculation | What it does not prove |
|---|---|---|
| 100 images | 100 × $0.024 = $2.40 | Final regional bill |
| 1,000 images | 1,000 × $0.024 = $24 | 4K pricing or quota availability |
| 10,000 images | 10,000 × $0.024 = $240 | Production uptime or rate limits |
Use the headline price for a controlled pilot only. Confirm current regional, resolution-specific, and mode-specific rates in Tencent Cloud before budgeting production volume.
What the quality evidence supports—and what it does not
AIBase’s launch coverage reports Tencent’s claim that overall capability improved by about 30% versus Hunyuan Image 3.0. The same reported internal designer evaluation positions the model near Seedream 5.0 Pro and ahead of Nano Banana Pro and Qwen-Image-3.0 Pro. Those are company claims, not independently reproducible benchmark results: the public reports do not provide prompts, scores, evaluator protocols, or a named test set.
Early X posts describe better texture retention and a successful multi-layer billboard text test, but those are anecdotal rather than benchmarks. For example, @Just_sharon7 described skin grain, fabric weave, and edge-light retention in one comparison, while @alextalksai reported a billboard test. The editing API and low pricing are documented; quality leadership is not.
Who should use Hy Image 3.5 Preview now
| Use case | Recommendation |
|---|---|
| Low-cost API pilot | Use it if you need reference-image conditioning or repeated edits and can tolerate preview behavior. |
| Posters and product graphics | Test text accuracy, subject preservation, edit consistency, latency, and failed-request billing on your own prompts. |
| Sole production provider | Avoid relying on it alone if you require a stable SLA, fixed pricing, documented international availability, local deployment, or an established benchmark record. |
The official sources cited here document cloud access rather than local deployment. Check Tencent’s model repositories and documentation before planning a ComfyUI workflow.
Hy Image 3.5 Preview API FAQ
How many reference images can Hy Image 3.5 Preview use?
Launch material describes up to five reference images per request. Confirm the limit exposed by the exact endpoint and account configuration you use.
Is the $0.024 price also the 4K price?
The cited $0.024 figure is a launch headline for image generation, while launch coverage emphasizes 2K and Tencent Cloud documents up to 4,096 × 4,096. Treat 4K pricing as unconfirmed until the live regional rate card shows it.
Is Hy Image 3.5 a stable GA release?
No. The available model is explicitly a Preview release. It is officially available, but that does not make it a final GA stability contract.
What is the Hy Image 3.5 Preview model ID?
Tencent Cloud’s TokenHub documentation lists hy-image-v3.5-preview.
Does it support image-to-image generation?
Yes. Tencent documents text-to-image, image-to-image, reference-image input, and multi-turn editing.
