> Doubao-Seedream-5.0-lite is the latest image-creation model released by ByteDance. For the first time, the model includes an online retrieval capability, allowing it to integrate real-time web information and improve the timeliness of generated images. At the same time, the model’s intelligence has been further upgraded, enabling it to accurately parse complex instructions and visual content. In addition, the model has been enhanced in terms of breadth of world knowledge, reference consistency, and generation quality in professional scenarios, better meeting enterprise-level visual-creation needs.

- Developer: Doubao
- Input modalities: text, image
- Pricing: per-generation — see https://aihubmix.com/model/doubao-seedream-5.0-lite

## Endpoints (base URL: https://aihubmix.com)

- `POST /ai/v1/images/generations` — image generation (`Authorization: Bearer $AIHUBMIX_API_KEY`)
- `POST /v1/images/edits` — image generation (`Authorization: Bearer $AIHUBMIX_API_KEY`)
- `POST /v1/images/generations` — image generation (`Authorization: Bearer $AIHUBMIX_API_KEY`)

## Example

```bash
curl -s https://aihubmix.com/ai/v1/images/generations \
  -H "Authorization: Bearer $AIHUBMIX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"doubao-seedream-5.0-lite","prompt":"<your prompt>"}'
```

The response carries the output URL(s) directly. Full parameter list: see the schema link below. Generation costs real money — check the price on the model page first.

Always-current parameter schema (authoritative, no auth):

```bash
curl -s https://aihubmix.com/call/schema/models/doubao-seedream-5.0-lite/endpoints
```

Output URLs are short-lived (roughly 30 minutes) and are downloaded with the same `Authorization: Bearer` header — fetch them promptly and store the content yourself.

## Errors

Error responses carry a `tid` (trace id) — include it when contacting support. Reference: https://docs.aihubmix.com/en/FAQs/HTTP-Codes.md

- 400 — parameter error; most are passed through from the upstream provider (media: `prompt_missing`, `size_not_supported`, `n_not_within_range`, …)
- 401 — missing `Authorization` header, or the key is invalid/expired
- 403 — `insufficient_user_quota` (top up at https://console.aihubmix.com/), account suspended, or this key is not allowed to use this model
- 429 — rate limited; back off and retry
- 503 — no channel can serve the request (check the model id and your access), or the upstream provider is throttling; retry later

- Generate runnable code programmatically: npm `@aihubmix/codegen` — the generator behind the Playground's "Get Code" (4 protocols × 7 languages, media endpoints included); the body it builds is the exact wire body the Playground sends, so generated snippets and real requests cannot diverge. `@aihubmix/model-schema` (npm) translates the parameter schema above into codegen input
