}模型方案控制着该密钥运行哪个上游引擎。有两个相互独立的调节项：
single_model—— 为每一次文本轮次锁定同一个引擎。这是一种确定性的直通模式，会跳过分类器（非常适合编码 / IDE 后端场景，也包括 自带模型（BYO） 的custom:引擎）。bindings—— 将各个模式重新映射到指定引擎；分类器依然负责路由，但每个模式所使用的引擎是被锁定的。
arca-velox-5.1、arca-magnus-5.1、anthropic/claude-sonnet-4.6、anthropic/claude-opus-4.8、anthropic/claude-haiku-4.5、google/gemini-2.5-pro、openai/gpt-4.1，或者你自己的 custom:<providerId>:<model>。
如果需要完整的可运行流程（分支、护栏节点、路由），请改用 编排器图 —— 它的优先级高于模型方案。
身份验证
需要具备billing 权限范围的 API 密钥；调用者必须是该密钥的所有者。
路径参数
string
必填
该 API 密钥的 UUID。
获取方案
GET /api/v1/keys/{id}/model-plan
object | null
被锁定的引擎（
{ upstream_id, fallback_upstream_id }），或 null。array
按模式的覆盖设置：
{ mode, upstream_id, fallback_upstream_id }。array
可供选择的引擎列表（平台内置引擎 + 你的自定义提供方），用于构建选择器。
替换方案
PUT /api/v1/keys/{id}/model-plan —— 完整替换这两个字段（需要发送完整的目标状态）。
object | null
{ upstream_id, fallback_upstream_id? }，用于为每一次文本轮次锁定同一个引擎；传 null 则清除该锁定。object[]
按模式的覆盖设置，每一项为
{ mode, upstream_id, fallback_upstream_id? }。所引用的每个上游 id 都会针对平台目录或你的自定义提供方进行校验。示例
curl -X PUT https://www.hitheo.ai/api/v1/keys/KEY_ID/model-plan \
-H "Authorization: Bearer $THEO_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "bindings": [
{ "mode": "fast", "upstream_id": "arca-velox-5.1" },
{ "mode": "think", "upstream_id": "arca-magnus-5.1" }
] }'
await theo.keys.setModelPlan("KEY_ID", {
single_model: { upstream_id: "anthropic/claude-opus-4.8" }, // 确定性直通
});
