在消息中定义工具（beta）

借助 inline-tools-2026-09-15 beta 标头，对话过程中系统消息内的 tool_addition 块可携带完整工具定义而非引用，因此你无需编辑 tools 即可在对话过程中添加工具、更改其架构，或将服务器工具迁移至更新版本，同时不会丢失提示词缓存。该功能适用于所有支持对话中途工具变更的模型，包括 Claude Opus 5.5。

例如，要在对话过程中定义自定义工具：

curl --location --request POST 'https://genaiapi.cloudsway.net/{ENDPOINT}/v1/messages' \
--header 'Authorization: Bearer {Your AK}' \
--header 'Content-Type: application/json' \
  -H "anthropic-version: 2023-06-01" \
  -H "anthropic-beta: inline-tools-2026-09-15" \
  -d '{
    "model": "claude-opus-5-5",
    "max_tokens": 1024,
    "tools": [
      {
        "name": "get_weather",
        "description": "Get the current weather for a location.",
        "input_schema": {
          "type": "object",
          "properties": {
            "location": {"type": "string", "description": "City name"}
          },
          "required": ["location"]
        }
      }
    ],
    "messages": [
      {
        "role": "user",
        "content": "How many orders shipped yesterday?"
      },
      {
        "role": "system",
        "content": [
          {
            "type": "tool_addition",
            "tool": {
              "type": "tool_definition",
              "definition": {
                "name": "db_query",
                "description": "Run a read-only SQL query against the analytics database.",
                "input_schema": {
                  "type": "object",
                  "properties": {"sql": {"type": "string"}},
                  "required": ["sql"]
                }
              }
            }
          }
        ]
      }
    ]
  }'

按需压缩（beta）

借助compact-2026-09-04 beta 标头，发送顶级压缩参数的请求会返回一个经过签名的压缩块，用于汇总整个会话，之后你可以先发送该压缩块，替代被汇总的消息。该功能适用于所有支持压缩的模型，包括 Claude Opus 5.5。你可以自行决定何时进行压缩，请求可在后台运行，且你保留的轮次中的思维块在替换后仍可保持有效（需满足压缩与保留思维中规定的条件），这一点对 Claude Opus 5.5 而言十分重要，因为其思维块与会话绑定。

# max_tokens caps the whole call, including any thinking, so allow several thousand tokens.
curl --location --request POST 'https://genaiapi.cloudsway.net/{ENDPOINT}/v1/messages' \
--header 'Authorization: Bearer {Your AK}' \
--header 'Content-Type: application/json' \
  -H "anthropic-version: 2023-06-01" \
  -H "anthropic-beta: compact-2026-09-04" \
  -d '{
    "model": "claude-opus-5-5",
    "max_tokens": 4096,
    "messages": [
      {"role": "user", "content": "I am building a recipe app. Help me name the main entities in the data model."},
      {"role": "assistant", "content": "Start with Recipe, Ingredient, and Step. Add a RecipeIngredient entry that holds the quantity and unit for each ingredient in a recipe."},
      {"role": "user", "content": "Good. Now suggest field names for Recipe."}
    ],
    "compaction": {"type": "summarize"}
  }'

返回示例：

  "type": "message",
  "role": "assistant",
  "model": "claude-opus-5-5",

      "type": "compaction",
      "content": "Summary of the conversation: the user is designing the data model for a recipe app. The entities agreed so far are Recipe, Ingredient, Step, and RecipeIngredient, which holds the quantity and unit. The user then asked for field names for Recipe.",

    }
