标准(异步)

POST /api/v1/claude-opus-5-5 — returns request_id, poll for result via /api/v1/predictions/{id}/result.

流式传输(SSE)

POST /api/v1/claude-opus-5-5/stream — returns a live SSE stream. 每个chunk: data: {"choices":[{"delta":{"content":"text"}}]}, ending with data: [DONE].

常见问题

常见问答

如何计算价格?

按 token 计费: $4.00 每百万输入 token 收费 $20.00 每百万输出 token 收费。 每次调用最低收费为 $0.0006. 每次调用后会根据模型返回的 token 数量扣除实际费用。

When should I use Opus 5.5 vs Opus 5 or Sonnet?

使用 Opus 5.5 for the most complex tasks requiring deep reasoning, large codebases, or maximum reliability, at a lower cost than Opus 5. 使用 Sonnet for faster responses and everyday tasks — it offers a better cost/performance trade-off for most use cases.

Does Claude Opus 5.5 support images?

可以。 Pass an image_url in the request body to include an image as part of the user message.
