Amazon Nova Micro

amazonamazon/nova-micro

供应商自营与 TheRouter 服务形态的差异

供应商自己运营时

AWS 通过 Bedrock bedrock-runtime 提供 Nova Micro，支持 Converse、Invoke、response streaming、guardrails、客户端工具调用和 prompt caching。Bedrock 原生模型卡标注 structured outputs 不支持，且只列出文本输入与文本输出。

在 TheRouter 上

TheRouter 将同一个纯文本模型以 OpenAI 兼容的 /v1/chat/completions 暴露为 amazon/nova-micro，并当前通过 US geo Bedrock profile 路由。TheRouter 不为该模型开放 Bedrock structured outputs 或非文本模态。

API 使用指南

Chat 调用

通过 TheRouter 的 OpenAI 兼容 chat 接口调用 Nova Micro，处理低成本文本任务。

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amazon/nova-micro",
    "messages": [{"role": "user", "content": "Classify this support ticket as billing, technical, or sales."}]
  }'

流式输出

Bedrock 支持 Nova Micro response streaming；适合聊天 UI 和较长摘要。

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amazon/nova-micro",
    "stream": true,
    "messages": [{"role": "user", "content": "Summarize this incident report in five bullets."}]
  }'

客户端工具调用

AWS 标注支持 client-side tool calling。适合让 Nova Micro 做分类或参数抽取后，再进行轻量调度。

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amazon/nova-micro",
    "messages": [{"role": "user", "content": "Route this ticket: I cannot update my card."}],
    "tools": [{
      "type": "function",
      "function": {
        "name": "route_ticket",
        "parameters": {"type": "object", "properties": {"queue": {"type": "string"}}}
      }
    }]
  }'

提示词约束 JSON

Nova Micro 不支持 Bedrock 原生 structured outputs。请显式要求 JSON，并在下游校验。

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amazon/nova-micro",
    "messages": [
      {"role": "system", "content": "Return only JSON with keys intent and urgency."},
      {"role": "user", "content": "Need this invoice fixed today."}
    ]
  }'
