API Message Batches mendukung rangkaian fitur yang sama dengan API Messages. Meskipun halaman ini berfokus pada cara menggunakan API Message Batches, lihat Contoh API Messages untuk contoh fitur API Messages.

Membuat Message Batch

import anthropic
from anthropic.types.message_create_params import MessageCreateParamsNonStreaming
from anthropic.types.messages.batch_create_params import Request

client = anthropic.Anthropic()

message_batch = client.messages.batches.create(
    requests=[
        Request(
            custom_id="my-first-request",
            params=MessageCreateParamsNonStreaming(
                model="claude-opus-4-20250514",
                max_tokens=1024,
                messages=[{
                    "role": "user",
                    "content": "Hello, world",
                }]
            )
        ),
        Request(
            custom_id="my-second-request",
            params=MessageCreateParamsNonStreaming(
                model="claude-opus-4-20250514",
                max_tokens=1024,
                messages=[{
                    "role": "user",
                    "content": "Hi again, friend",
                }]
            )
        )
    ]
)
print(message_batch)
JSON
{
  "id": "msgbatch_013Zva2CMHLNnXjNJJKqJ2EF",
  "type": "message_batch",
  "processing_status": "in_progress",
  "request_counts": {
    "processing": 2,
    "succeeded": 0,
    "errored": 0,
    "canceled": 0,
    "expired": 0
  },
  "ended_at": null,
  "created_at": "2024-09-24T18:37:24.100435Z",
  "expires_at": "2024-09-25T18:37:24.100435Z",
  "cancel_initiated_at": null,
  "results_url": null
}

​
Polling untuk penyelesaian Message Batch

Untuk melakukan polling pada Message Batch, Anda memerlukan id-nya, yang disediakan dalam respons saat membuat permintaan atau dengan mendaftar batch. Contoh id: msgbatch_013Zva2CMHLNnXjNJJKqJ2EF.

import anthropic

client = anthropic.Anthropic()

message_batch = None
while True:
    message_batch = client.messages.batches.retrieve(
        MESSAGE_BATCH_ID
    )
    if message_batch.processing_status == "ended":
        break
              
    print(f"Batch {MESSAGE_BATCH_ID} is still processing...")
    time.sleep(60)
print(message_batch)

​
Mendaftar semua Message Batch dalam Workspace

import anthropic

client = anthropic.Anthropic()

# Automatically fetches more pages as needed.
for message_batch in client.messages.batches.list(
    limit=20
):
    print(message_batch)
Output
{
  "id": "msgbatch_013Zva2CMHLNnXjNJJKqJ2EF",
  "type": "message_batch",
  ...
}
{
  "id": "msgbatch_01HkcTjaV5uDC8jWR4ZsDV8d",
  "type": "message_batch",
  ...
}

​
Mengambil Hasil Message Batch

Setelah status Message Batch Anda adalah ended, Anda akan dapat melihat results_url dari batch dan mengambil hasil dalam bentuk file .jsonl.

import anthropic

client = anthropic.Anthropic()

# Stream results file in memory-efficient chunks, processing one at a time
for result in client.messages.batches.results(
    MESSAGE_BATCH_ID,
):
    print(result)
Output
{
  "id": "my-second-request",
  "result": {
    "type": "succeeded",
    "message": {
      "id": "msg_018gCsTGsXkYJVqYPxTgDHBU",
      "type": "message",
      ...
    }
  }
}
{
  "custom_id": "my-first-request",
  "result": {
    "type": "succeeded",
    "message": {
      "id": "msg_01XFDUDYJgAACzvnptvVoYEL",
      "type": "message",
      ...
    }
  }
}

​
Membatalkan Message Batch

Segera setelah pembatalan, status processing_status batch akan menjadi canceling. Anda dapat menggunakan teknik polling untuk penyelesaian batch yang sama untuk melakukan polling kapan pembatalan diselesaikan karena batch yang dibatalkan juga akan berakhir dengan status ended dan mungkin berisi hasil.

import anthropic

client = anthropic.Anthropic()

message_batch = client.messages.batches.cancel(
    MESSAGE_BATCH_ID,
)
print(message_batch)
JSON
{
  "id": "msgbatch_013Zva2CMHLNnXjNJJKqJ2EF",
  "type": "message_batch",
  "processing_status": "canceling",
  "request_counts": {
    "processing": 2,
    "succeeded": 0,
    "errored": 0,
    "canceled": 0,
    "expired": 0
  },
  "ended_at": null,
  "created_at": "2024-09-24T18:37:24.100435Z",
  "expires_at": "2024-09-25T18:37:24.100435Z",
  "cancel_initiated_at": "2024-09-24T18:39:03.114875Z",
  "results_url": null
}
