Doubao Seed 2.0 Mini API
Doubao Seed 2.0 Mini is the cheap production default on NextModel at $0.03 input and $0.3 output per 1M tokens, for classification, short summaries, and other jobs where a long answer is a bug. The page lists the public id you send to the OpenAI-compatible endpoint, the listed input and output price, and the cases where you should escalate to a stronger model instead of squeezing this one.

Doubao Seed 2.0 Mini via NextModel: 256k-token context; Starting at $0.03 / 1M tokens in / $0.3 / 1M tokens out per 1M tokens. Capabilities: streaming.
Best use cases
- You already know the output shape: a label, a short rewrite, a routing decision.
- Volume is high enough that a premium model's output tokens would dominate the bill.
- You can keep a fallback model behind the same base URL when this one is wrong.
When not to use
- The user will read the answer as-is and you cannot stand a thin or sloppy paragraph.
- The prompt needs a large repo, a long PDF, or multi-step tool use.
- You have not tested it on your own Chinese or English samples yet.

FAQ
Doubao Seed 2.0 Mini API questions
What model id do I send for Doubao Seed 2.0 Mini?
Send doubao-seed-2-0-mini to https://api.nextmodel.app/v1. Keep your OpenAI SDK. If that id is missing from /v1/models, the page is stale and you should not ship traffic.
When should I stop using Seed 2.0 Mini?
Move up when reviews, agents, or final customer answers start failing in ways a cheaper model cannot fix. Price is not a reason to stay.
