Seedream 4.0 API

Seedream 4.0 is available through the zcloud gateway behind one API key, alongside every other model in the catalog. Seedream 4.0 API pricing is pay-as-you-go: $8.496093 per 1M input tokens and $8.496093 per 1M output tokens — no subscription, no monthly minimum, and the same OpenAI-compatible endpoint your tools already use.

zcloud meters every request per token and settles it in real time, with live rates always visible on the pricing page.

Seedream 4.0 runs behind the same OpenAI-compatible and Anthropic-compatible endpoints as the rest of the catalog, so existing tooling keeps working after a one-line base-URL change — a practical fit for chat products, coding agents and batch jobs that need frontier quality without official-API prices.
