Seedream 5.0 Lite API
Seedream 5.0 Lite turns detailed prompts into images and supports reference-guided editing. APINEED offers a simple per-image rate with a tested 2048×2048 starting point.
Released on February 13, 2026, Lite emphasizes reasoning-driven image creation. The official model supports outputs from 2K through 4K; this page offers square presets and single-image responses. A 1024×1024 request was rejected by our upstream, so the playground starts at 2048×2048. Broader native capabilities such as search and batch generation are not switches in this integration.
Playground
Generate with Seedream 5.0 Lite, review the output, and use the same request shape in your application.

ByteDance documents the broader model capability. APINEED separately defines the model ID, endpoint, parameter whitelist, authentication, and billing behavior shown on this page.
Image pricing
One generated image is one billing unit. No per-token multiplication is needed.
| Billing item | Baseline price | APINEED price |
|---|---|---|
| One generated image | $0.032836 | $0.029552 |
Availability
APINEED monitors Seedream 5.0 Lite API availability. Applications should preserve request and task IDs and handle upstream failures explicitly.
No model-specific availability history is published yet. A successful request is not an uptime guarantee.
Reasoning-driven generation
The official Lite announcement describes stronger reasoning for image creation. Explain relationships between objects and any factual constraints in the visual brief. [1]
Larger square canvases
The selector offers 2048, 3072, and 4096 pixel square outputs. Only the 2048 square preset has been exercised in the real upstream check for this release. [2][3]
One billable output
The current production configuration charges per generated image rather than per prompt token. A successful 2048 square request settled at approximately $0.029552. [3]
Prepare a clear visual brief
Start with the tested square. Use 2048x2048 for a first integration check before evaluating larger canvases for your own material.
Describe relationships. Specify the subject, setting, lighting, and how objects relate spatially, rather than adding many unrelated style keywords.

Quick Start
Call Seedream 5.0 Lite with the verified APINEED endpoint and model-specific request shape.
Create an API key
Store your APINEED key server-side as API_NEED_API_KEY.
export API_NEED_API_KEY=sk-apineed-v1-...Send the request
Use seedream-5.0-lite with POST /v1/images/generations.

Read every item in data[] and handle either its url or b64_json value.

Parameters
These controls follow APINEED's current DTO and adapter behavior. Unsupported upstream-only fields are intentionally omitted.
| Name | Type | Values | Description |
|---|---|---|---|
model | string | Required | Set seedream-5.0-lite. |
prompt | string | Required | Your visual brief or instructions for the referenced image. |
image | string | string[] | Optional | Provide reference URLs when editing; omit this field to create an image from text. The documented maximum is 14 references. |
size | string | Optional | Square presets: 2048x2048 (tested default), 3072x3072, 4096x4096. Lite requires at least 3,686,400 pixels; 1024x1024 is not supported. |
n | integer | 1 | The playground generates a single image per request. |
response_format | string | Optional | url in this playground. Read the returned data array and download the image promptly. |
Seedream 5.0 Lite API questions
Practical answers for choosing, integrating, pricing, and operating the Seedream 5.0 Lite API on APINEED.
Why is 1024×1024 not offered for Seedream Lite?
Our upstream rejected that size because Lite requires at least 3,686,400 pixels. The default square is 2048×2048, which produced a valid image in the production smoke test. [2][3]
What does one Lite image cost on APINEED?
The reviewed rate is approximately $0.029552 per generated image, based on CNY 0.22 divided by 6.7 and discounted to 90%. The page refreshes its selling price from the public pricing catalog. [3]
Are 3K and 4K Lite outputs also available?
The official specification supports 2K, 3K, and 4K. This form includes 3072×3072 and 4096×4096 options; those larger options are documented but were not included in our paid generation check. [2][3]
Which options are necessary for a first Lite request?
Supply the model and prompt, and use the shown 2048x2048 size for a predictable start. The working example uses n: 1 and response_format: url without quality, compression, or output-format overrides. [3]
Is the Lite gallery image a real response?
Yes. It is the JPEG returned by a real APINEED call with the teapot prompt. The default watermark is visible. It demonstrates a successful request rather than a promise that all prompts render similarly. [3]
Does this Lite page expose native search or image batches?
No. The current playground submits one image request and does not expose a search control, streaming mode, or multi-output batch. Reference URLs use the documented image field, with real editing validation still pending. [2][3]
