[Announcement](https://www.anthropic.com/claude-sonnet-5-5) · [What’s new](https://platform.claude.com/docs/id/models/sonnet-5-5/whats-new-sonnet-5-5) · [Migration guide](https://platform.claude.com/docs/id/models/sonnet-5-5/migration-guide)
## Ikhtisar
Claude Sonnet 5.5 menawarkan kombinasi terbaik antara kecepatan dan kecerdasan. Lima "breaking change" (perubahan yang merusak kompatibilitas) memengaruhi kode yang sudah berjalan di Claude Sonnet 5:
* [Matikan pemikiran di awal dengan `between_tools`](https://platform.claude.com/docs/id/models/sonnet-5-5/whats-new-sonnet-5-5#turn-off-up-front-thinking).
* [Penggunaan alat paksa mengembalikan error](https://platform.claude.com/docs/id/models/sonnet-5-5/whats-new-sonnet-5-5#forced-tool-use-is-not-supported).
* [Blok pemikiran terikat pada model dan percakapan](https://platform.claude.com/docs/id/models/sonnet-5-5/whats-new-sonnet-5-5#thinking-blocks-are-tied-to-the-model-that-produced-them).
* [Di Claude API dan Google Cloud, alat computer use `computer_20251124` yang lebih lama tidak diterima](https://platform.claude.com/docs/id/models/sonnet-5-5/whats-new-sonnet-5-5#computer-20251124-is-not-supported).
* [Alat advisor menolak Claude Opus 4.8, Claude Opus 4.7, Claude Sonnet 5, dan Claude Haiku 5.5 sebagai advisor](https://platform.claude.com/docs/id/models/sonnet-5-5/whats-new-sonnet-5-5#advisor-tool-pairings).
Satu perubahan lagi mengubah bentuk respons tanpa menggagalkan permintaan apa pun: [teks di antara pemanggilan alat dikembalikan dalam blok `thinking`](https://platform.claude.com/docs/id/models/sonnet-5-5/whats-new-sonnet-5-5#text-between-tool-calls). Aplikasi yang melakukan streaming teks tersebut kepada penggunanya akan menjadi senyap di antara pemanggilan alat hingga aplikasi tersebut menetapkan nilai `display` yang mengembalikan teks, atau mematikan pemikiran di awal dengan `between_tools`.

## Perbandingan
| Model | Context | Max output | Price / MTok | Latency | Thinking | Default effort | Knowledge cutoff |
| :-------------------------------------------------------------------------------- | :------ | :--------- | :----------------- | :------- | :------------------- | :------------- | :--------------- |
| [Claude Fable 5.1](https://platform.claude.com/docs/id/models/fable-5-1/overview) | 1M | 128K | $10 / $50 | Slower | Adaptive (always on) | `high` | Jun 2026 |
| [Claude Opus 5.5](https://platform.claude.com/docs/id/models/opus-5-5/overview) | 1M | 128K | $4 / $20 | Moderate | Adaptive (always on) | `medium` | Jun 2026 |
| **Claude Sonnet 5.5** (this model) | 1M | 128K | $2 / $10 | Fast | Adaptive | `high` | Jun 2026 |
| [Claude Haiku 5.5](https://platform.claude.com/docs/id/models/haiku-5-5/overview) | 1M | 128K | From $0.10 / $0.50 | Fastest | Adaptive | `medium` | Jun 2026 |
* **Context:** 1M tokens is roughly 555k words or 2.5M Unicode characters on the current tokenizer (introduced with Claude Opus 4.7); models before it fit about 750k words in 1M tokens. 200k tokens is roughly 150k words.
* **Max output:** Synchronous Messages API limit. On the Message Batches API, Claude Opus 5.5, Claude Opus 5, Claude Sonnet 5.5, Claude Sonnet 5, Claude Haiku 5.5, Claude Opus 4.8, Claude Opus 4.7, Claude Opus 4.6, and Claude Sonnet 4.6 support up to 300k output tokens with the output-300k-2026-03-24 beta header.
* **Price / MTok:** Input / output, base price per million tokens. Batch API requests are 50% off; prompt caching reads cost 10% of the base input price (2.5% on Claude Fable 5.1 and Claude Mythos 5.1, 5% on Claude Opus 5.5 and Claude Sonnet 5.5). See Pricing for the full list.
* **Latency:** Comparative latency, relative to the current lineup, as published in the models overview. Actual latency depends on prompt length, output length, and thinking effort.
* **Thinking:** Adaptive thinking lets the model decide how much to think, steered by effort. Extended thinking is the manual budget\_tokens mode on earlier models.
* **Default effort:** The effort parameter’s default on the Claude API. Models without a value don’t support the parameter.
* **Knowledge cutoff:** Reliable knowledge cutoff: the date through which the model’s knowledge is most extensive and reliable.

## Hal yang perlu diketahui
* "Adaptive thinking" (pemikiran adaptif) aktif secara default. Pengaturan thinking terendah adalah `between_tools`, yang menonaktifkan thinking di awal. Pengaturan ini berfungsi pada effort `high` atau lebih rendah. Lihat [Yang baru di Claude Sonnet 5.5](https://platform.claude.com/docs/id/models/sonnet-5-5/whats-new-sonnet-5-5#turn-off-up-front-thinking).
* Mengatur `temperature`, `top_p`, atau `top_k` ke nilai non-default akan menghasilkan error 400.
* Panjang prompt minimum yang dapat di-cache adalah 512 token. Lihat ["Prompt caching" (caching prompt)](https://platform.claude.com/docs/id/build-with-claude/prompt-caching#cache-limitations).
* Pada [Message Batches API](https://platform.claude.com/docs/id/build-with-claude/batch-processing#extended-output-beta), Claude Sonnet 5.5 mendukung hingga 300k token output dengan header beta `output-300k-2026-03-24`.
* Kueri batas dan kemampuan secara terprogram dengan [Models API](https://platform.claude.com/docs/id/api/models/list).
