# 视觉模型（Anthropic 兼容，复用默认映射）
|
||
|
||
旧 docs.anthropic.com 跳转至此官方域名，正文证明 Messages 的 image/base64/media_type/data 结构；max_tokens=1024 是本仓输出预算策略，官网示例使用该值不证明它是默认或上限。认证、API 版本和 content.0.text 不因本篇已读而视作全部核验；任意网关仍需验收。
|
||
|
||
数据区中的 claims 是复核边界，pending 字段是当前配置快照，不能当官方证明。enabled/priority/timeout 是产品策略，未复制到合同中。更新合同必须重新读官方正文、记录实际证明字段；结构校验不等于账号可用。
