Pricing
Seed-2.0-Code API pricing
| Price per 1M tokens | Input | Output |
|---|---|---|
| Standard | $0.50 | $3 |
| Prompts of 128,000+ tokens | $1 | $6 |
Output costs 6.0× the input price, so long replies drive the bill more than long prompts. No cached-input price is published, so repeated prompt prefixes are billed at the full input price. Once a single prompt reaches 128,000 tokens, the whole request is billed at the higher long-context rate shown above.

Context
Context window
Seed-2.0-Code accepts up to 262,144 tokens per request, roughly 196,608 English words or 393 pages. That budget is shared between your prompt and the reply, and a single reply is capped at 131,072 tokens.
Filling the whole window with one prompt costs about $0.26 at list price, so for repeated long-document work, retrieval (sending only the relevant parts) or prompt caching is usually much cheaper.
