Fitur ini didukung bersama compaction sesuai permintaan, di mana Anda yang memutuskan kapan ringkasan ditulis (lihat [Compaction sesuai permintaan](https://platform.claude.com/docs/id/build-with-claude/compaction-on-demand)). Untuk memilih di antara keduanya, lihat [Pilih cara melakukan compaction](https://platform.claude.com/docs/id/build-with-claude/compaction#choose-how-to-compact). Compaction memperluas panjang konteks efektif untuk percakapan dan tugas yang berjalan lama dengan meringkas konteks lama secara otomatis saat mendekati batas "context window" (jendela konteks). Compaction juga menjaga konteks aktif tetap kecil: seiring percakapan bertambah panjang, kualitas respons menurun, sehingga compaction menggantikan konten lama dengan ringkasan yang padat. Untuk penjelasan lebih mendalam tentang mengapa konteks panjang menurunkan kualitas dan bagaimana compaction membantu, lihat [Effective context engineering](https://www.anthropic.com/engineering/effective-context-engineering-for-ai-agents). Ini ideal untuk: * Percakapan multi-giliran berbasis chat di mana Anda ingin pengguna menggunakan satu chat dalam jangka waktu yang lama * Prompt berorientasi tugas yang memerlukan banyak pekerjaan lanjutan (sering kali berupa "tool use" (penggunaan alat)) yang mungkin melebihi jendela konteks ## Cara kerja compaction Ketika compaction diaktifkan, Claude secara otomatis meringkas percakapan Anda ketika mencapai ambang batas token yang dikonfigurasi. API akan: 1. Mendeteksi ketika token input mencapai ambang batas pemicu yang Anda tentukan. 2. Menghasilkan ringkasan dari percakapan saat ini. 3. Membuat blok `compaction` yang berisi ringkasan tersebut. 4. Melanjutkan respons dengan konteks yang telah dipadatkan. Pada permintaan berikutnya, tambahkan respons ke pesan Anda. API secara otomatis membuang semua blok konten sebelum blok `compaction`, dan melanjutkan percakapan dari ringkasan. ![Compaction flow (alur pemadatan): ketika token input mencapai trigger (pemicu), Claude menulis ringkasan ke dalam compaction block (blok compaction) dan melanjutkan](https://platform.claude.com/docs/id/images/compaction-flow.svg) ## Penggunaan dasar Aktifkan compaction dengan menambahkan strategi `compact_20260112` ke `context_management.edits` dalam permintaan Messages API Anda. ```bash cURL curl https://api.anthropic.com/v1/messages \ -H "x-api-key: $ANTHROPIC_API_KEY" \ -H "anthropic-version: 2023-06-01" \ -H "anthropic-beta: compact-2026-01-12" \ -H "content-type: application/json" \ -d '{ "model": "claude-opus-5-5", "max_tokens": 4096, "messages": [ { "role": "user", "content": "Help me build a website" } ], "context_management": { "edits": [ { "type": "compact_20260112" } ] } }' ``` ```bash CLI ant beta:messages create --beta compact-2026-01-12 <<'YAML' model: claude-opus-5-5 max_tokens: 4096 messages: - role: user content: Help me build a website context_management: edits: - type: compact_20260112 YAML ``` ```python Python client = anthropic.Anthropic() messages = [{"role": "user", "content": "Help me build a website"}] response = client.beta.messages.create( betas=["compact-2026-01-12"], model="claude-opus-5-5", max_tokens=4096, messages=messages, context_management={"edits": [{"type": "compact_20260112"}]}, ) # Tambahkan respons (termasuk blok compaction apa pun) untuk melanjutkan percakapan messages.append({"role": "assistant", "content": response.content}) ``` ```typescript TypeScript const client = new Anthropic(); const messages: Anthropic.Beta.Messages.BetaMessageParam[] = [ { role: "user", content: "Help me build a website" } ]; const response = await client.beta.messages.create({ betas: ["compact-2026-01-12"], model: "claude-opus-5-5", max_tokens: 4096, messages, context_management: { edits: [ { type: "compact_20260112" } ] } }); // Tambahkan respons (termasuk blok compaction apa pun) untuk melanjutkan percakapan messages.push({ role: "assistant", content: response.content }); ``` ```csharp C# AnthropicClient client = new(); var messages = new List { new() { Role = Role.User, Content = "Help me build a website" } }; var parameters = new MessageCreateParams { Betas = ["compact-2026-01-12"], Model = Model.ClaudeOpus5_5, MaxTokens = 4096, Messages = messages, ContextManagement = new BetaContextManagementConfig { Edits = [new BetaCompact20260112Edit()] } }; var response = await client.Beta.Messages.Create(parameters); // Tambahkan respons (termasuk blok compaction apa pun) untuk melanjutkan percakapan messages.Add(new BetaMessageParam { Role = Role.Assistant, Content = response.Content.Select(block => new BetaContentBlockParam(block.Json)).ToList() }); Console.WriteLine(response); ``` ```go Go client := anthropic.NewClient() messages := []anthropic.BetaMessageParam{ anthropic.NewBetaUserMessage(anthropic.NewBetaTextBlock("Help me build a website")), } response, err := client.Beta.Messages.New(context.TODO(), anthropic.BetaMessageNewParams{ Model: anthropic.ModelClaudeOpus5_5, MaxTokens: 4096, Messages: messages, ContextManagement: anthropic.BetaContextManagementConfigParam{ Edits: []anthropic.BetaContextManagementConfigEditUnionParam{ {OfCompact20260112: &anthropic.BetaCompact20260112EditParam{}}, }, }, Betas: []anthropic.AnthropicBeta{"compact-2026-01-12"}, }) if err != nil { log.Fatal(err) } // Tambahkan respons (termasuk blok compaction apa pun) untuk melanjutkan percakapan messages = append(messages, response.ToParam()) fmt.Println(response) ``` ```java Java import com.anthropic.models.beta.messages.BetaContextManagementConfig; import com.anthropic.models.beta.messages.BetaCompact20260112Edit; // ...

Setiap prompt default menginstruksikan Claude untuk menulis ringkasan di dalam tag `

` yang berisi informasi yang diperlukan untuk melanjutkan tugas dalam jendela konteks berikutnya. Sebagai contoh, beberapa model menggunakan prompt berikut: ```text wrap You have written a partial transcript for the initial task above. Please write a summary of the transcript. The purpose of this summary is to provide continuity so you can continue to make progress towards solving the task in a future context, where the raw history above may not be accessible and will be replaced with this summary. Write down anything that would be helpful, including the state, next steps, learnings etc. You must wrap your summary in a

block. ``` Anda dapat memberikan instruksi kustom melalui parameter `instructions`. Instruksi kustom tidak melengkapi prompt default. Instruksi tersebut menggantikannya sepenuhnya: ```bash cURL curl https://api.anthropic.com/v1/messages \ -H "x-api-key: $ANTHROPIC_API_KEY" \ -H "anthropic-version: 2023-06-01" \ -H "anthropic-beta: compact-2026-01-12" \ -H "content-type: application/json" \ -d '{ "model": "claude-opus-5-5", "max_tokens": 4096, "messages": [ { "role": "user", "content": "Hello, Claude" } ], "context_management": { "edits": [ { "type": "compact_20260112", "instructions": "Focus on preserving code snippets, variable names, and technical decisions." } ] } }' ``` ```bash CLI ant beta:messages create --beta compact-2026-01-12 <<'YAML' model: claude-opus-5-5 max_tokens: 4096 messages: - role: user content: Hello, Claude context_management: edits: - type: compact_20260112 instructions: >- Focus on preserving code snippets, variable names, and technical decisions.

Ini memungkinkan Anda menambahkan blok konten tambahan (seperti mempertahankan pesan terbaru atau pesan berorientasi instruksi tertentu) sebelum API melanjutkan respons. Ketika diaktifkan, API mengembalikan pesan dengan stop reason `compaction` setelah menghasilkan blok compaction: ```bash cURL # pause_after_compaction menghentikan respons tepat setelah ringkasan # compaction sehingga Anda dapat menyesuaikan pesan sebelum melanjutkan.

Anda dapat menggabungkan `pause_after_compaction` dengan penghitung compaction untuk memperkirakan penggunaan kumulatif dan menyelesaikan tugas dengan baik begitu anggaran tercapai. Contoh ini hanya muncul dalam bahasa SDK: nilainya terletak pada logika pelacakan anggaran di sekitar permintaan. Permintaan mentahnya menggabungkan `trigger` dari [Konfigurasi pemicu](https://platform.claude.com/docs/id/build-with-claude/compaction-threshold#trigger-configuration) dengan `pause_after_compaction` dari [Berhenti sejenak setelah compaction](https://platform.claude.com/docs/id/build-with-claude/compaction-threshold#pausing-after-compaction). ```python Python client = anthropic.Anthropic() messages = [{"role": "user", "content": "Hello, Claude"}] TRIGGER_THRESHOLD = 100_000 TOTAL_TOKEN_BUDGET = 3_000_000 n_compactions = 0 response = client.beta.messages.create( betas=["compact-2026-01-12"], model="claude-opus-5-5", max_tokens=4096, messages=messages, context_management={ "edits": [ { "type": "compact_20260112", "trigger": {"type": "input_tokens", "value": TRIGGER_THRESHOLD}, "pause_after_compaction": True, } ] }, ) if response.stop_reason == "compaction": n_compactions += 1 messages.append({"role": "assistant", "content": response.content}) # Perkirakan total token yang terpakai; minta model menyelesaikan jika melebihi anggaran if n_compactions * TRIGGER_THRESHOLD >= TOTAL_TOKEN_BUDGET: messages.append( { "role": "user", "content": "Please wrap up your current work and summarize the final state.", } ) ``` ```typescript TypeScript const client = new Anthropic(); const messages: Anthropic.Beta.Messages.BetaMessageParam[] = [ { role: "user", content: "Hello, Claude" } ]; const TRIGGER_THRESHOLD = 100_000; const TOTAL_TOKEN_BUDGET = 3_000_000; let compactionCount = 0; const response = await client.beta.messages.create({ betas: ["compact-2026-01-12"], model: "claude-opus-5-5", max_tokens: 4096, messages, context_management: { edits: [ { type: "compact_20260112", trigger: { type: "input_tokens", value: TRIGGER_THRESHOLD }, pause_after_compaction: true } ] } }); if (response.stop_reason === "compaction") { compactionCount += 1; messages.push({ role: "assistant", content: response.content }); // Perkirakan total token yang terpakai; minta model menyelesaikan jika melebihi anggaran if (compactionCount * TRIGGER_THRESHOLD >= TOTAL_TOKEN_BUDGET) { messages.push({ role: "user", content: "Please wrap up your current work and summarize the final state." }); } } ``` ```csharp C# AnthropicClient client = new(); List messages = [new() { Role = Role.User, Content = "Hello, Claude" }]; const int TriggerThreshold = 100_000; const int TotalTokenBudget = 3_000_000; int compactionCount = 0; var response = await client.Beta.Messages.Create(new() { Betas = ["compact-2026-01-12"], Model = Model.ClaudeOpus5_5, MaxTokens = 4096, Messages = messages, ContextManagement = new BetaContextManagementConfig { Edits = [new BetaCompact20260112Edit { Trigger = new BetaInputTokensTrigger(TriggerThreshold), PauseAfterCompaction = true }] } }); if (response.StopReason == BetaStopReason.Compaction) { compactionCount += 1; messages.Add(new() { Role = Role.Assistant, Content = response.Content.Select(b => new BetaContentBlockParam(b.Json)).ToList() }); // Perkirakan total token yang terpakai; minta model menyelesaikan jika melebihi anggaran if (compactionCount * TriggerThreshold >= TotalTokenBudget) { messages.Add(new() { Role = Role.User, Content = "Please wrap up your current work and summarize the final state." }); } } Console.WriteLine(response); ``` ```go Go client := anthropic.NewClient() messages := []anthropic.BetaMessageParam{anthropic.NewBetaUserMessage(anthropic.NewBetaTextBlock("Hello, Claude"))} const triggerThreshold = 100_000 const totalTokenBudget = 3_000_000 compactionCount := 0 response, err := client.Beta.Messages.New(context.TODO(), anthropic.BetaMessageNewParams{ Model: anthropic.ModelClaudeOpus5_5, MaxTokens: 4096, Messages: messages, ContextManagement: anthropic.BetaContextManagementConfigParam{ Edits: []anthropic.BetaContextManagementConfigEditUnionParam{ {OfCompact20260112: &anthropic.BetaCompact20260112EditParam{ Trigger: anthropic.BetaInputTokensTriggerParam{Value: triggerThreshold}, PauseAfterCompaction: anthropic.Bool(true), }}, }, }, Betas: []anthropic.AnthropicBeta{"compact-2026-01-12"}, }) if err != nil { log.Fatal(err) } if response.StopReason == "compaction" { compactionCount++ messages = append(messages, response.ToParam()) // Perkirakan total token yang terpakai; minta model menyelesaikan jika melebihi anggaran if compactionCount*triggerThreshold >= totalTokenBudget { messages = append(messages, anthropic.NewBetaUserMessage(anthropic.NewBetaTextBlock("Please wrap up your current work and summarize the final state."))) } } fmt.Println(response) ``` ```java Java import com.anthropic.models.beta.messages.BetaContextManagementConfig; import com.anthropic.models.beta.messages.BetaCompact20260112Edit; import com.anthropic.models.beta.messages.BetaInputTokensTrigger; import com.anthropic.models.beta.messages.BetaStopReason; // ...

Percakapan yang berjalan lama dapat menghasilkan beberapa compaction. Blok compaction terakhir mencerminkan status akhir prompt, menggantikan konten sebelumnya dengan ringkasan yang dihasilkan. ```json Output { "content": [ { "type": "compaction", "content": "Summary of the conversation: The user requested help building a web scraper..." }, { "type": "text", "text": "Based on our conversation so far..." } ] } ``` ### Mengirimkan kembali blok compaction Anda harus mengirimkan kembali blok `compaction` ke API pada permintaan berikutnya untuk melanjutkan percakapan dengan prompt yang telah dipersingkat. Pendekatan paling sederhana adalah menambahkan seluruh konten respons ke pesan Anda: ```bash cURL # Konten respons, termasuk blok compaction, harus dikirim kembali ke # API sebagai giliran asisten pada permintaan berikutnya. Mengelola daftar pesan itu # tidak cocok untuk perintah shell sekali jalan; lihat tab CLI dan SDK # untuk alur lengkapnya. Permintaan pertama: curl https://api.anthropic.com/v1/messages \ -H "x-api-key: $ANTHROPIC_API_KEY" \ -H "anthropic-version: 2023-06-01" \ -H "anthropic-beta: compact-2026-01-12" \ -H "content-type: application/json" \ -d '{ "model": "claude-opus-5-5", "max_tokens": 4096, "messages": [ { "role": "user", "content": "Hello, Claude" } ], "context_management": { "edits": [ { "type": "compact_20260112" } ] } }' ``` ```bash CLI ant beta:messages create \ --beta compact-2026-01-12 \ --transform content \ --format jsonl <<'YAML' > content.json model: claude-opus-5-5 max_tokens: 4096 messages: - role: user content: Hello, Claude context_management: edits: - type: compact_20260112 YAML # Setelah menerima respons dengan blok compaction, tambahkan sebagai # giliran asisten dan lanjutkan percakapan ant beta:messages create --beta compact-2026-01-12 < { new() { Role = Role.User, Content = "Help me build a web scraper" } }; var response = await client.Beta.Messages.Create(new() { Betas = ["compact-2026-01-12"], Model = Model.ClaudeOpus5_5, MaxTokens = 4096, Messages = messages, ContextManagement = new BetaContextManagementConfig { Edits = [new BetaCompact20260112Edit()] } }); messages.Add(new BetaMessageParam { Role = Role.Assistant, Content = response.Content.Select(block => new BetaContentBlockParam(block.Json)).ToList() }); messages.Add(new BetaMessageParam { Role = Role.User, Content = "Now add error handling" }); var nextResponse = await client.Beta.Messages.Create(new() { Betas = ["compact-2026-01-12"], Model = Model.ClaudeOpus5_5, MaxTokens = 4096, Messages = messages, ContextManagement = new BetaContextManagementConfig { Edits = [new BetaCompact20260112Edit()] } }); Console.WriteLine(nextResponse); ``` ```go Go client := anthropic.NewClient() messages := []anthropic.BetaMessageParam{ anthropic.NewBetaUserMessage(anthropic.NewBetaTextBlock("Help me build a web scraper")), } compactEdit := anthropic.BetaContextManagementConfigParam{ Edits: []anthropic.BetaContextManagementConfigEditUnionParam{ {OfCompact20260112: &anthropic.BetaCompact20260112EditParam{}}, }, } response, err := client.Beta.Messages.New(context.TODO(), anthropic.BetaMessageNewParams{ Model: anthropic.ModelClaudeOpus5_5, MaxTokens: 4096, Messages: messages, ContextManagement: compactEdit, Betas: []anthropic.AnthropicBeta{"compact-2026-01-12"}, }) if err != nil { log.Fatal(err) } messages = append(messages, response.ToParam()) messages = append(messages, anthropic.NewBetaUserMessage(anthropic.NewBetaTextBlock("Now add error handling"))) nextResponse, err := client.Beta.Messages.New(context.TODO(), anthropic.BetaMessageNewParams{ Model: anthropic.ModelClaudeOpus5_5, MaxTokens: 4096, Messages: messages, ContextManagement: compactEdit, Betas: []anthropic.AnthropicBeta{"compact-2026-01-12"}, }) if err != nil { log.Fatal(err) } fmt.Println(nextResponse) ``` ```java Java import com.anthropic.models.beta.messages.BetaContextManagementConfig; import com.anthropic.models.beta.messages.BetaCompact20260112Edit; // ...

Jika Anda memanggil `client.messages` dan melakukan serialisasi blok sendiri, `model_dump()` biasa akan menambahkan `text: null` dan `citations: null` ke blok `compaction`. API kemudian menolak permintaan tersebut dengan error 400 (`Extra inputs are not permitted`). Sebagai gantinya, gunakan `to_dict()` atau `model_dump(exclude_none=True)`. [Melanjutkan dari ringkasan](https://platform.claude.com/docs/id/build-with-claude/compaction-on-demand#continue-from-the-summary) memberikan saran yang sama untuk compaction sesuai permintaan. Ketika API menerima blok `compaction`, semua blok konten sebelumnya diabaikan. Anda dapat memilih untuk: * Mempertahankan pesan asli dalam daftar Anda dan membiarkan API menangani penghapusan konten yang telah dipadatkan * Membuang pesan yang telah dipadatkan secara manual dan hanya menyertakan blok compaction dan seterusnya Pada Claude Fable 5.1, Claude Mythos 5.1, Claude Opus 5.5, Claude Sonnet 5.5, dan Claude Haiku 5.5, blok thinking dari sebelum blok `compaction` tidak dibawa ke depan, sehingga ringkasan adalah satu-satunya yang dimiliki model dari pekerjaan sebelumnya tersebut. Jika Anda menulis `instructions` sendiri, beri tahu model apa yang harus dipertahankan dalam ringkasan; lihat [Beri tahu model apa yang harus dipertahankan dalam ringkasan compaction](https://platform.claude.com/docs/id/build-with-claude/prompt-engineering/prompting-claude-fable-5-1#tell-the-model-what-to-preserve-in-compaction-summaries). ### Streaming Blok compaction di-stream secara berbeda dari blok teks.

Anda dapat menambahkan breakpoint `cache_control` pada blok compaction untuk melakukan cache terhadap konten yang telah diringkas. ```json { "role": "assistant", "content": [ { "type": "compaction", "content": "[summary text]", "cache_control": { "type": "ephemeral" } }, { "type": "text", "text": "Based on our conversation..." } ] } ``` #### Memaksimalkan cache hit dengan prompt sistem Ketika compaction terjadi, ringkasan menjadi konten baru yang perlu ditulis ke cache. Tanpa breakpoint cache tambahan, hal ini juga akan membatalkan "system prompt" (prompt sistem) yang telah di-cache, sehingga prompt tersebut harus di-cache ulang bersama ringkasan compaction. Untuk memaksimalkan tingkat cache hit, tambahkan breakpoint `cache_control` di akhir prompt sistem Anda. Ini menjaga prompt sistem tetap di-cache secara terpisah dari percakapan, sehingga ketika compaction terjadi: * Cache prompt sistem tetap valid dan dibaca dari cache * Hanya ringkasan compaction yang perlu ditulis sebagai entri cache baru ```bash cURL curl https://api.anthropic.com/v1/messages \ -H "x-api-key: $ANTHROPIC_API_KEY" \ -H "anthropic-version: 2023-06-01" \ -H "anthropic-beta: compact-2026-01-12" \ -H "content-type: application/json" \ -d '{ "model": "claude-opus-5-5", "max_tokens": 4096, "system": [ { "type": "text", "text": "You are a helpful coding assistant...", "cache_control": { "type": "ephemeral" } } ], "messages": [ { "role": "user", "content": "Hello, Claude" } ], "context_management": { "edits": [ { "type": "compact_20260112" } ] } }' ``` ```bash CLI ant beta:messages create --beta compact-2026-01-12 <<'YAML' model: claude-opus-5-5 max_tokens: 4096 system: - type: text text: You are a helpful coding assistant... cache_control: type: ephemeral messages: - role: user content: Hello, Claude context_management: edits: - type: compact_20260112 YAML ``` ```python Python client = anthropic.Anthropic() messages = [{"role": "user", "content": "Hello, Claude"}] response = client.beta.messages.create( betas=["compact-2026-01-12"], model="claude-opus-5-5", max_tokens=4096, system=[ { "type": "text", "text": "You are a helpful coding assistant...", "cache_control": { "type": "ephemeral" }, # Cache the system prompt separately } ], messages=messages, context_management={"edits": [{"type": "compact_20260112"}]}, ) ``` ```typescript TypeScript const client = new Anthropic(); const messages: Anthropic.Beta.Messages.BetaMessageParam[] = [ { role: "user", content: "Hello, Claude" } ]; const response = await client.beta.messages.create({ betas: ["compact-2026-01-12"], model: "claude-opus-5-5", max_tokens: 4096, system: [ { type: "text", text: "You are a helpful coding assistant...", cache_control: { type: "ephemeral" } // Cache the system prompt separately } ], messages, context_management: { edits: [{ type: "compact_20260112" }] } }); ``` ```csharp C# var client = new AnthropicClient(); var parameters = new MessageCreateParams { Betas = ["compact-2026-01-12"], Model = Model.ClaudeOpus5_5, MaxTokens = 4096, System = new List { new() { Text = "You are a helpful coding assistant...", CacheControl = new BetaCacheControlEphemeral() } }, Messages = [new() { Role = Role.User, Content = "Hello, Claude" }], ContextManagement = new BetaContextManagementConfig { Edits = [new BetaCompact20260112Edit()] } }; var response = await client.Beta.Messages.Create(parameters); Console.WriteLine(response); ``` ```go Go client := anthropic.NewClient() response, err := client.Beta.Messages.New(context.TODO(), anthropic.BetaMessageNewParams{ Model: anthropic.ModelClaudeOpus5_5, MaxTokens: 4096, System: []anthropic.BetaTextBlockParam{ { Text: "You are a helpful coding assistant...", CacheControl: anthropic.NewBetaCacheControlEphemeralParam(), }, }, Messages: []anthropic.BetaMessageParam{anthropic.NewBetaUserMessage(anthropic.NewBetaTextBlock("Hello, Claude"))}, ContextManagement: anthropic.BetaContextManagementConfigParam{ Edits: []anthropic.BetaContextManagementConfigEditUnionParam{ {OfCompact20260112: &anthropic.BetaCompact20260112EditParam{}}, }, }, Betas: []anthropic.AnthropicBeta{"compact-2026-01-12"}, }) if err != nil { log.Fatal(err) } fmt.Println(response) ``` ```java Java import com.anthropic.models.beta.messages.BetaContextManagementConfig; import com.anthropic.models.beta.messages.BetaCompact20260112Edit; import com.anthropic.models.beta.messages.BetaCacheControlEphemeral; // ...

API mengembalikan informasi penggunaan yang terperinci dalam respons: ```json Output { "usage": { "input_tokens": 23000, "output_tokens": 1000, "iterations": [ { "type": "compaction", "input_tokens": 180000, "output_tokens": 3500 }, { "type": "message", "input_tokens": 23000, "output_tokens": 1000 } ] } } ``` Array `iterations` menunjukkan penggunaan untuk setiap iterasi sampling. Ketika compaction terjadi, Anda akan melihat iterasi `compaction` diikuti oleh iterasi `message` utama. `input_tokens` dan `output_tokens` tingkat atas sama persis dengan iterasi `message` dalam contoh ini karena hanya ada satu iterasi non-compaction. Jumlah token pada iterasi terakhir mencerminkan ukuran konteks efektif setelah compaction. `input_tokens` dan `output_tokens` tingkat atas tidak mencakup penggunaan iterasi compaction. Keduanya mencerminkan jumlah dari semua iterasi non-compaction. Untuk menghitung total token yang dikonsumsi dan ditagih untuk suatu permintaan, jumlahkan seluruh entri dalam array `usage.iterations`. Jika sebelumnya Anda mengandalkan `usage.input_tokens` dan `usage.output_tokens` untuk pelacakan biaya atau audit, Anda perlu memperbarui logika pelacakan Anda untuk mengagregasi seluruh `usage.iterations` ketika compaction diaktifkan. Dengan beta compaction diaktifkan, setiap respons menyertakan `usage.iterations`, bahkan jika tidak ada compaction yang terjadi. Entri `compaction` hanya muncul ketika compaction baru dipicu selama permintaan. Menerapkan ulang blok `compaction` sebelumnya tidak menimbulkan biaya compaction tambahan, dan kolom penggunaan tingkat atas tetap akurat dalam kasus tersebut. ## Menggabungkan dengan fitur lain ### Alat server Saat menggunakan server tools (seperti pencarian web), pemicu compaction diperiksa di awal setiap iterasi sampling. Compaction dapat terjadi beberapa kali dalam satu permintaan, tergantung pada ambang batas pemicu Anda dan jumlah output yang dihasilkan. ### Penghitungan token Endpoint penghitungan token (`/v1/messages/count_tokens`) menerapkan blok `compaction` yang sudah ada dalam prompt Anda tetapi tidak memicu compaction baru. Gunakan endpoint ini untuk memeriksa jumlah token efektif Anda setelah compaction sebelumnya: ```bash cURL curl https://api.anthropic.com/v1/messages/count_tokens \ -H "x-api-key: $ANTHROPIC_API_KEY" \ -H "anthropic-version: 2023-06-01" \ -H "anthropic-beta: compact-2026-01-12" \ -H "content-type: application/json" \ -d '{ "model": "claude-opus-5-5", "messages": [ { "role": "user", "content": "Hello, Claude" } ], "context_management": { "edits": [ { "type": "compact_20260112" } ] } }' ``` ```bash CLI CURRENT=$(ant beta:messages count-tokens \ --beta compact-2026-01-12 \ --transform input_tokens \ --raw-output <<'YAML' model: claude-opus-5-5 messages: - role: user content: Hello, Claude context_management: edits: - type: compact_20260112 YAML ) ORIGINAL=$(ant beta:messages count-tokens \ --beta compact-2026-01-12 \ --transform context_management.original_input_tokens \ --raw-output <<'YAML' model: claude-opus-5-5 messages: - role: user content: Hello, Claude context_management: edits: - type: compact_20260112 YAML ) printf 'Current tokens: %s\n' "$CURRENT" printf 'Original tokens: %s\n' "$ORIGINAL" ``` ```python Python client = anthropic.Anthropic() messages = [{"role": "user", "content": "Hello, Claude"}] count_response = client.beta.messages.count_tokens( betas=["compact-2026-01-12"], model="claude-opus-5-5", messages=messages, context_management={"edits": [{"type": "compact_20260112"}]}, ) print(f"Current tokens: {count_response.input_tokens}") print(f"Original tokens: {count_response.context_management.original_input_tokens}") ``` ```typescript TypeScript const client = new Anthropic(); const messages: Anthropic.Beta.Messages.BetaMessageParam[] = [ { role: "user", content: "Summarize the key points of our conversation so far." } ]; const countResponse = await client.beta.messages.countTokens({ betas: ["compact-2026-01-12"], model: "claude-opus-5-5", messages, context_management: { edits: [{ type: "compact_20260112" }] } }); console.log(`Current tokens: ${countResponse.input_tokens}`); console.log(`Original tokens: ${countResponse.context_management!.original_input_tokens}`); ``` ```csharp C# AnthropicClient client = new(); List messages = [new() { Role = Role.User, Content = "Hello" }]; var countParams = new MessageCountTokensParams { Model = Model.ClaudeOpus5_5, Messages = messages, ContextManagement = new BetaContextManagementConfig { Edits = [new BetaCompact20260112Edit()] }, Betas = ["compact-2026-01-12"] }; var countResponse = await client.Beta.Messages.CountTokens(countParams); Console.WriteLine($"Current tokens: {countResponse.InputTokens}"); Console.WriteLine($"Original tokens: {countResponse.ContextManagement?.OriginalInputTokens}"); ``` ```go Go client := anthropic.NewClient() messages := []anthropic.BetaMessageParam{anthropic.NewBetaUserMessage(anthropic.NewBetaTextBlock("Hello, Claude"))} countResponse, err := client.Beta.Messages.CountTokens(context.TODO(), anthropic.BetaMessageCountTokensParams{ Model: anthropic.ModelClaudeOpus5_5, Messages: messages, ContextManagement: anthropic.BetaContextManagementConfigParam{ Edits: []anthropic.BetaContextManagementConfigEditUnionParam{ {OfCompact20260112: &anthropic.BetaCompact20260112EditParam{}}, }, }, Betas: []anthropic.AnthropicBeta{"compact-2026-01-12"}, }) if err != nil { log.Fatal(err) } fmt.Printf("Current tokens: %d\n", countResponse.InputTokens) fmt.Printf("Original tokens: %d\n", countResponse.ContextManagement.OriginalInputTokens) ``` ```java Java import com.anthropic.models.beta.messages.BetaMessageTokensCount; import com.anthropic.models.beta.messages.MessageCountTokensParams; import com.anthropic.models.beta.messages.BetaContextManagementConfig; import com.anthropic.models.beta.messages.BetaCompact20260112Edit; // ...

Blok-blok tersebut dihasilkan ketika riwayat lengkap masih ada, sehingga tidak lagi lolos [pemeriksaan percakapan](https://platform.claude.com/docs/id/build-with-claude/thinking#preserved-in-conversation). Di mana pemeriksaan tersebut diberlakukan, permintaan lanjutan ditolak dengan error 400. Blok teks dan blok alat yang dipertahankan dapat dibiarkan apa adanya. Membiarkan API meringkas semuanya, tanpa menyisipkan kembali giliran sebelumnya, akan menghindari hal ini. Pada Claude Sonnet 5.5, `block_binding` hanya berfungsi dengan `thinking: {"type": "adaptive"}`. Dengan `between_tools`, hapus blok-blok tersebut sebagai gantinya. Pada Claude Haiku 5.5, `block_binding` hanya berfungsi dengan `thinking: {"type": "adaptive"}`, jadi dengan `thinking: {"type": "disabled"}`, hapus blok-blok tersebut sebagai gantinya. Berikut adalah contoh yang menggunakan `pause_after_compaction` untuk mempertahankan pertukaran sebelumnya dan pesan pengguna saat ini (total tiga pesan) alih-alih meringkasnya. Contoh ini mempertahankan blok teks dan blok alatnya tanpa perubahan, menghapus blok `thinking` dan `redacted_thinking` dari giliran asisten yang dipertahankan, dan membuang giliran tersebut jika tidak ada lagi yang tersisa: ```bash cURL # curl mengirim permintaan satu per satu; kelola array messages di # skrip pemanggil.

Tidak ada opsi untuk menggunakan model yang berbeda (misalnya, yang lebih murah) untuk ringkasan. * **Compaction mungkin gagal ketika alat didefinisikan:** Ketika permintaan Anda menyertakan `tools`, model terkadang memanggil alat selama langkah peringkasan internal alih-alih menulis ringkasan. Ketika hal ini terjadi, respons berisi blok `compaction` dengan `content: null`. Untuk mencegahnya, atur [`instructions`](https://platform.claude.com/docs/id/build-with-claude/compaction-threshold#custom-summarization-instructions) ke prompt yang secara eksplisit memberi tahu model untuk tidak memanggil alat, misalnya: ```text wrap Summarize the transcript inside

tags. Include relevant information in the summary for continuing the task in the next context window. Do not call any tools while writing this summary; respond with text only. ``` ## Langkah selanjutnya Kelola konteks percakapan secara otomatis seiring pertumbuhannya dengan pengeditan konteks. Pelajari tentang ukuran jendela konteks dan strategi pengelolaannya. Jelajahi implementasi praktis yang mengelola percakapan berjalan lama dengan compaction memori sesi instan menggunakan threading latar belakang dan caching prompt.
