Claude dapat memberikan kutipan terperinci saat menjawab pertanyaan tentang dokumen, membantu Anda melacak dan memverifikasi sumber di balik setiap respons.

Semua [model aktif](https://platform.claude.com/docs/id/models/overview) mendukung kutipan.

<Tip>
  Bagikan umpan balik dan saran Anda tentang fitur kutipan menggunakan [formulir umpan balik kutipan](https://forms.gle/9n9hSrKnKe3rpowH9).

<Tip>
  **Perbandingan dengan pendekatan berbasis prompt**

  Dibandingkan dengan meminta Claude untuk mengutip sumber, fitur kutipan menawarkan keuntungan berikut:

  * **Penghematan biaya:** Jika pendekatan berbasis prompt Anda meminta Claude untuk menghasilkan kutipan langsung, Anda mungkin melihat penghematan biaya karena `cited_text` tidak dihitung terhadap token output Anda.
  * **Keandalan kutipan yang lebih baik:** Karena API mengurai kutipan ke dalam format respons yang dijelaskan di bagian berikut dan mengekstrak `cited_text` secara langsung, kutipan dijamin berisi penunjuk yang valid ke dokumen yang disediakan.
  * **Kualitas kutipan yang ditingkatkan:** Dalam evaluasi Anthropic, fitur kutipan secara signifikan lebih mungkin mengutip kutipan yang paling relevan dari dokumen dibandingkan pendekatan yang murni berbasis prompt.
</Tip>

***

## Cara kerja kutipan

Integrasikan kutipan dengan Claude dalam langkah-langkah berikut:

<Steps>
  <Step title="Sediakan dokumen dan aktifkan kutipan">
    * Sertakan dokumen dalam salah satu format yang didukung: dokumen [PDF](https://platform.claude.com/docs/id/build-with-claude/citations#pdf-documents), [teks biasa](https://platform.claude.com/docs/id/build-with-claude/citations#plain-text-documents), atau [konten kustom](https://platform.claude.com/docs/id/build-with-claude/citations#custom-content-documents).
    * Atur `citations.enabled=true` pada setiap dokumen Anda. Saat ini, kutipan harus diaktifkan pada semua atau tidak sama sekali dari dokumen dalam sebuah permintaan.
    * Hanya kutipan teks yang saat ini didukung. Kutipan gambar belum memungkinkan.
  </Step>

  <Step title="Dokumen diproses">
    * Konten dokumen "dipotong" (chunked) untuk menentukan granularitas minimum dari kutipan yang mungkin. Misalnya, pemotongan kalimat memungkinkan Claude mengutip satu kalimat atau merangkai beberapa kalimat berurutan untuk mengutip paragraf atau bagian yang lebih panjang.

      * **Untuk PDF:** Teks diekstrak seperti yang dijelaskan dalam [dukungan PDF](https://platform.claude.com/docs/id/build-with-claude/pdf-support) dan konten dipotong menjadi kalimat. Mengutip gambar dari PDF saat ini tidak didukung.
      * **Untuk dokumen teks biasa:** Konten dipotong menjadi kalimat yang dapat dikutip.
      * **Untuk dokumen konten kustom:** Blok konten yang Anda sediakan digunakan apa adanya dan tidak ada pemotongan lebih lanjut yang dilakukan.
  </Step>

  <Step title="Claude memberikan respons yang dikutip">
    * Respons sekarang dapat mencakup beberapa blok teks di mana setiap blok teks dapat berisi klaim yang dibuat Claude dan daftar kutipan yang mendukung klaim tersebut.

    * Kutipan merujuk ke lokasi tertentu dalam dokumen sumber. Format kutipan ini bergantung pada jenis dokumen yang dikutip.

      * **Untuk PDF:** Kutipan mencakup rentang nomor halaman (diindeks mulai dari 1).
      * **Untuk dokumen teks biasa:** Kutipan mencakup rentang indeks karakter (diindeks mulai dari 0).
      * **Untuk dokumen konten kustom:** Kutipan mencakup rentang indeks blok konten (diindeks mulai dari 0) yang sesuai dengan daftar konten asli yang disediakan.

    * Indeks dokumen disediakan untuk menunjukkan sumber referensi dan diindeks mulai dari 0 sesuai dengan daftar semua dokumen dalam permintaan asli Anda.
  </Step>
</Steps>

<Tip>
  **Pemotongan otomatis vs konten kustom**

  Secara default, dokumen teks biasa dan PDF secara otomatis dipotong menjadi kalimat. Jika Anda memerlukan kontrol lebih atas granularitas kutipan (misalnya, untuk poin-poin atau transkrip), gunakan dokumen konten kustom sebagai gantinya. Lihat [Jenis dokumen](https://platform.claude.com/docs/id/build-with-claude/citations#document-types) untuk detail lebih lanjut.

  Misalnya, jika Anda ingin Claude dapat mengutip kalimat tertentu dari potongan RAG Anda, Anda harus menempatkan setiap potongan RAG ke dalam dokumen teks biasa. Jika tidak, jika Anda tidak ingin ada pemotongan lebih lanjut yang dilakukan, atau jika Anda ingin menyesuaikan pemotongan tambahan apa pun, Anda dapat menempatkan potongan RAG ke dalam dokumen konten kustom.
</Tip>

### Konten yang dapat dikutip versus tidak dapat dikutip

* Teks yang ditemukan dalam konten `source` dokumen dapat dikutip.
* `title` dan `context` adalah bidang opsional yang diteruskan ke model tetapi tidak digunakan untuk konten yang dikutip.
* `title` terbatas panjangnya, sehingga bidang `context` berguna untuk menyimpan metadata dokumen sebagai teks atau JSON yang distringifikasi.

### Indeks kutipan

* Indeks dokumen diindeks mulai dari 0 dari daftar semua blok konten dokumen dalam permintaan (mencakup semua pesan).
* Indeks karakter diindeks mulai dari 0 dengan indeks akhir eksklusif.
* Nomor halaman diindeks mulai dari 1 dengan nomor halaman akhir eksklusif.
* Indeks blok konten diindeks mulai dari 0 dengan indeks akhir eksklusif dari daftar `content` yang disediakan dalam dokumen konten kustom.

### Biaya token

* Mengaktifkan kutipan menyebabkan sedikit peningkatan token input karena penambahan prompt sistem dan pemotongan dokumen.
* Namun, fitur kutipan sangat efisien dengan token output. Secara internal, model menghasilkan kutipan dalam format standar yang kemudian diurai menjadi teks yang dikutip dan indeks lokasi dokumen. Bidang `cited_text` disediakan untuk kenyamanan dan tidak dihitung terhadap token output.
* Ketika diteruskan kembali dalam giliran percakapan berikutnya, `cited_text` juga tidak dihitung terhadap token input.

### Kompatibilitas fitur

Kutipan bekerja bersama dengan fitur API lainnya termasuk [caching prompt](https://platform.claude.com/docs/id/build-with-claude/prompt-caching), [penghitungan token](https://platform.claude.com/docs/id/build-with-claude/token-counting), dan [pemrosesan batch](https://platform.claude.com/docs/id/build-with-claude/batch-processing).

<Warning>
  **Kutipan dan output terstruktur tidak kompatibel**

  Kutipan tidak dapat digunakan bersama dengan [output terstruktur](https://platform.claude.com/docs/id/build-with-claude/structured-outputs). Jika Anda mengaktifkan kutipan pada dokumen yang disediakan pengguna (blok `document` atau blok `search_result`) dan juga menyertakan parameter `output_config.format` (atau parameter `output_format` yang sudah usang), API mengembalikan error 400.

  Ini karena kutipan memerlukan penyisipan blok kutipan dengan output teks, yang tidak kompatibel dengan batasan skema JSON yang ketat dari output terstruktur.
</Warning>

#### Menggunakan caching prompt dengan kutipan

Kutipan dan caching prompt dapat digunakan bersama secara efektif.

Blok kutipan yang dihasilkan dalam respons tidak dapat di-cache secara langsung, tetapi dokumen sumber yang dirujuknya dapat di-cache. Untuk mengoptimalkan kinerja, terapkan `cache_control` pada blok konten dokumen tingkat atas Anda.

Dalam contoh ini:

* Konten dokumen di-cache menggunakan `cache_control` pada blok dokumen.
* Kutipan diaktifkan pada dokumen.
* Claude dapat menghasilkan respons dengan kutipan sambil memanfaatkan konten dokumen yang di-cache.
* Permintaan berikutnya yang menggunakan dokumen yang sama memanfaatkan konten yang di-cache.

## Jenis dokumen

### Memilih jenis dokumen

Tiga jenis dokumen didukung untuk kutipan. Dokumen dapat disediakan langsung dalam pesan (base64, teks, atau URL) atau diunggah melalui [Files API](https://platform.claude.com/docs/id/build-with-claude/files) dan dirujuk dengan `file_id`:

| Jenis         | Terbaik untuk                                                      | Pemotongan                    | Format kutipan                          |
| ------------- | ------------------------------------------------------------------ | ----------------------------- | --------------------------------------- |
| Teks biasa    | Dokumen teks sederhana, prosa                                      | Kalimat                       | Indeks karakter (diindeks mulai dari 0) |
| PDF           | File PDF dengan konten teks                                        | Kalimat                       | Nomor halaman (diindeks mulai dari 1)   |
| Konten kustom | Daftar, transkrip, pemformatan khusus, kutipan yang lebih granular | Tidak ada pemotongan tambahan | Indeks blok (diindeks mulai dari 0)     |

<Note>
  Untuk jenis file yang tidak didukung oleh blok `document` (misalnya, .docx dan .xlsx), konversikan file ke teks biasa dan sertakan konten langsung dalam konten pesan. File yang sudah berupa teks biasa, seperti file .csv dan .md, juga dapat diunggah dengan tipe konten `text/plain` yang eksplisit. Lihat [Bekerja dengan format file lain](https://platform.claude.com/docs/id/build-with-claude/files#working-with-other-file-formats).
</Note>

### Dokumen teks biasa

Dokumen teks biasa secara otomatis dipotong menjadi kalimat. Anda dapat menyediakannya secara inline atau dengan referensi menggunakan `file_id` mereka:

<Tabs>
  <Tab title="Teks inline">
    Contoh pengantar di bagian atas halaman ini menunjukkan permintaan teks biasa yang lengkap di setiap SDK. Blok dokumen menggunakan sumber `text`:

    ```json
    {
      "type": "document",
      "source": {
        "type": "text",
        "media_type": "text/plain",
        "data": "Plain text content..."
      },
      "title": "Document Title",
      "context": "Context about the document that will not be cited from",
      "citations": { "enabled": true }
    }
    ```
  </Tab>

  <Tab title="Files API">
    Contoh-contoh ini merujuk ke file yang diunggah melalui [Files API](https://platform.claude.com/docs/id/build-with-claude/files) sebagai sumber `document`.

### Dokumen PDF

Dokumen PDF dapat disediakan sebagai data yang dikodekan base64, URL, atau dengan `file_id`. Teks PDF diekstrak dan dipotong menjadi kalimat. Karena kutipan gambar belum didukung, PDF yang merupakan hasil pindaian dokumen dan tidak mengandung teks yang dapat diekstrak tidak dapat dikutip.

## Struktur respons

Ketika kutipan diaktifkan, respons mencakup beberapa blok teks dengan kutipan:

```json
{
  "content": [
    { "type": "text", "text": "According to the document, " },
    {
      "type": "text",
      "text": "the grass is green",
      "citations": [
        {
          "type": "char_location",
          "cited_text": "The grass is green.",
          "document_index": 0,

          "start_char_index": 0,
          "end_char_index": 20
        }
      ]
    },
    { "type": "text", "text": " and " },
    {
      "type": "text",
      "text": "the sky is blue",
      "citations": [
        {
          "type": "char_location",
          "cited_text": "The sky is blue.",
          "document_index": 0,
          "document_title": "Example Document",

      ]
    },
    {

      "text": ". Information from page 5 states that "
    },
    {
      "type": "text",
      "text": "water is essential",
      "citations": [

          "document_index": 1,
          "document_title": "PDF Document",
          "start_page_number": 5,
          "end_page_number": 6
        }

          "document_index": 2,
          "document_title": "Custom Content Document",
          "start_block_index": 0,
          "end_block_index": 1
        }
      ]
    }
  ]
}
```

### Dukungan streaming

Untuk respons streaming, kutipan tiba sebagai tipe delta `citations_delta` di dalam event `content_block_delta`. Setiap delta berisi satu kutipan untuk ditambahkan ke daftar `citations` pada blok konten `text` saat ini.

<AccordionGroup>
  <Accordion title="Contoh event streaming">
    ```sse
    event: message_start
    data: {"type": "message_start", ...}

    event: content_block_start

    event: content_block_delta
    data: {"type": "content_block_delta", "index": 0,
           "delta": {"type": "text_delta", "text": "According to..."}}

                         ...
                     }}}

    event: content_block_stop
