Doubao Seed 2.0 Mini API guide: pricing, use cases, and OpenAI-compatible calls

Direct answer

A developer guide to using Doubao Seed 2.0 Mini through NextModel, including price, best use cases, and quickstart code. This guide is written for UK product and platform teams comparing model quality, spend, routing policy, and production rollout risk.

What is Doubao Seed 2.0 Mini good for?

Doubao Seed 2.0 Mini is a low-cost Chinese model candidate for high-volume product work: support drafts, classification, summarization, Chinese Q&A, and lightweight multimodal understanding. In the NextModel catalog it is marked as a production entry with ¥0.2 per 1M input tokens and ¥2 per 1M output tokens.

Call Doubao through the OpenAI SDK

The model can be called with the same OpenAI-compatible chat-completions shape used elsewhere in the docs.

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.nextmodel.app/v1"
)

resp = client.chat.completions.create(
    model="doubao-seed-2-0-mini",
    messages=[{"role": "user", "content": "Hello from NextModel"}]
)

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