Multimodal versions can. The console shows which Doubao Seed versions accept image input, and you send images in the OpenAI-compatible message format.

Which model ID do I use for Doubao Seed?

Use an ID returned by GET /v1/models . Doubao Seed IDs are confirmed when accounts open, and the same call lists every other model your key can use.

Do I need a separate ByteDance account?

At a glance

Chat and multimodal, next to Seedance.

Doubao Seed handles text and, on multimodal versions, images. Seedance, ByteDance's separate video line, runs on the same GotoRamp account and balance.

GotoRamp LLC isn't affiliated with ByteDance. We offer a model only once we hold written terms for it through a channel that allows our use in each market.

Use cases

What teams use it for.

General chat covers most in-product text work; multimodal versions add images. Check which version does what in the console.

In-app assistants

Answer booking, order and account questions inside your app, with a system prompt that sets the tone, the scope and the moment to hand over to a person.

Captions and alt text

On versions that accept image input, describe product photos, write alt text and social captions, or check a creative against the brief before it goes to review.

Shot lists for video

Draft and refine shot descriptions in text, then send the approved one to Seedance. Text is billed per token and video per second, from one balance.

Call it with the OpenAI SDK

Write the shot list in text first.

Set base_url to https://api.gotoramp.ai/v1, read your key from GOTORAMP_API_KEY, and use a Doubao Seed model ID returned by GET /v1/models. This example drafts three vertical shots for a short ad.

To turn a shot into video, send it to POST /v1/video/generations; see the video API reference and the Seedance prompt guide. Chat fields are in the chat completions reference.

Python

# pip install openai
import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.gotoramp.ai/v1",
    api_key=os.environ["GOTORAMP_API_KEY"],
)

shots = client.chat.completions.create(
    model="<model-id from GET /v1/models>",  # a Doubao Seed model
    messages=[
        {"role": "system", "content": "Write video prompts: subject, action, camera, light, sound. One line per shot."},
        {"role": "user", "content": "Three 9:16 shots for a kopi stall in Penang at 7 a.m., for a 15-second ad."},
    ],
    max_tokens=300,
)

print(shots.choices[0].message.content)
