Interactions API kini tersedia secara umum. Sebaiknya gunakan API ini untuk mengakses semua fitur dan model terbaru.

Google menggunakan teknologi AI untuk menerjemahkan konten ke dalam bahasa pilihan Anda. Terjemahan AI mungkin mengandung kesalahan.

Pemikiran Gemini

Model seri Gemini 3 dan 2.5 menggunakan "proses berpikir" yang secara signifikan meningkatkan kemampuan penalaran dan perencanaan multi-langkahnya, sehingga sangat efektif untuk tugas-tugas kompleks seperti coding, matematika tingkat lanjut, dan analisis data.

Saat Anda menggunakan model yang berbasis penalaran, Gemini akan melakukan penalaran secara internal sebelum memberikan respons. Interactions API menampilkan alasan ini melalui langkah-langkah thought, langkah-langkah khusus yang muncul secara kronologis bersama panggilan fungsi, input pengguna, atau output model dalam array steps.

Setiap langkah pemikiran berisi dua kolom:

Kolom	Wajib	Deskripsi
`signature`	✅ Ya	Representasi terenkripsi dari status penalaran internal model. Selalu ada, bahkan saat model melakukan penalaran minimal.
`summary`	❌ Tidak	Serangkaian konten (teks dan/atau gambar) yang merangkum penalaran. Mungkin kosong, bergantung pada konfigurasi `thinking_summaries`, apakah model melakukan penalaran yang cukup, atau jenis konten (misalnya, latensi gambar mungkin tidak memiliki ringkasan teks).

Interaksi dengan penalaran

Memulai interaksi dengan model yang berbasis penalaran serupa dengan permintaan interaksi lainnya. Tentukan salah satu model dengan dukungan penalaran di kolom model:

Python

from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3.8-flash",
    input="Explain the concept of Occam's Razor and provide a simple, everyday example."
)
print(interaction.output_text)

JavaScript

const client = new GoogleGenAI({});

const interaction = await client.interactions.create({

Ringkasan penalaran

Ringkasan pemikiran memberikan insight tentang proses penalaran internal model. Secara default, hanya output akhir yang ditampilkan. Anda dapat mengaktifkan ringkasan pemikiran dengan thinking_summaries:

Python

from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3.8-flash",
    input="What is the sum of the first 50 prime numbers?",
    generation_config={
        "thinking_summaries": "auto"
    }
)

for step in interaction.steps:
    if step.type == "thought":
        print("Thought summary:")
        if step.summary:
            for content_block in step.summary:

                    print(content_block.text)
        print()
    elif step.type == "model_output":
        for content_block in step.content:

Blok pemikiran mungkin berisi hanya tanda tangan tanpa ringkasan dalam kasus berikut:

Permintaan sederhana, di mana model tidak cukup bernalar untuk membuat ringkasan
thinking_summaries: "none", tempat ringkasan dinonaktifkan secara eksplisit
Jenis konten pemikiran tertentu, seperti gambar, mungkin tidak memiliki ringkasan teks

Kode Anda harus selalu menangani blok pemikiran saat summary kosong atau tidak ada.

Streaming dengan penalaran

Gunakan streaming untuk menerima ringkasan pemikiran inkremental selama pembuatan. Blok pemikiran dikirimkan menggunakan Peristiwa yang Dikirim Server (SSE) dengan dua jenis delta yang berbeda:

Jenis delta	Berisi	Waktu dikirim
`thought_summary`	Konten ringkasan teks atau gambar	Satu atau beberapa delta dengan ringkasan inkremental
`thought_signature`	Tanda tangan kriptografi	delta terakhir sebelum `step.stop`

Mengontrol pemikiran

Model Gemini terlibat dalam pemikiran dinamis secara default, dengan otomatis menyesuaikan jumlah upaya penalaran berdasarkan kompleksitas permintaan. Anda dapat mengontrol perilaku ini menggunakan parameter thinking_level.

Batas token dan `max_output_tokens`

Parameter pembuatan max_output_tokens menetapkan jumlah maksimum token yang dapat dihasilkan respons, termasuk token pemikiran.

Jika ditetapkan, parameter ini bertindak sebagai batas akhir yang ketat yang diterapkan oleh infrastruktur tanpa mengubah cara model mengalokasikan anggaran pemikirannya (thinking_level).

Jika model mencapai batas ini saat melakukan penalaran, model akan berhenti menghasilkan dengan status "incomplete" dan menampilkan output yang terpotong atau kosong (sambil tetap menagih token pemikiran yang dihasilkan). Untuk mengurangi biaya atau latensi tanpa memangkas respons, turunkan thinking_level (low atau medium) daripada menetapkan max_output_tokens kecil.

Tanda tangan penalaran

Tanda tangan pemikiran adalah representasi terenkripsi dari penalaran internal model. Mereka diwajibkan untuk mempertahankan kontinuitas penalaran di seluruh interaksi multi-giliran.

Interactions API membuat penanganan tanda pikiran jauh lebih sederhana daripada generateContent API.

Mode Stateful (Direkomendasikan)

Secara default, saat Anda menggunakan Interactions API dalam mode stateful (dengan menyetel store: true dan meneruskan previous_interaction_id pada giliran berikutnya), server akan otomatis mengelola status percakapan, termasuk semua blok pemikiran dan tanda tangan. Dalam mode ini, Anda tidak perlu melakukan apa pun terkait tanda tangan. Semua permintaan ditangani sepenuhnya di sisi server.

Mode tanpa status

Jika Anda mengelola status percakapan sendiri (mode stateless) dan meneruskan histori lengkap input dan output di setiap permintaan:

Anda HARUS selalu mengirim ulang semua blok thought persis seperti yang diterima dari model.
Anda TIDAK boleh menghapus atau mengubah blok pemikiran dari histori, karena blok tersebut berisi tanda tangan yang diperlukan agar model dapat melanjutkan penalaran.
Saat beralih model dalam sesi, Anda tetap harus mengirim ulang blok pemikiran model sebelumnya. Backend mengelola kompatibilitas.

Harga

Jika penalaran diaktifkan, harga respons adalah jumlah token output dan token penalaran. Anda bisa mendapatkan total jumlah token pemikiran yang dihasilkan dari kolom total_thought_tokens.

Python

print("Thoughts tokens:", interaction.usage.total_thought_tokens)
print("Output tokens:", interaction.usage.total_output_tokens)

JavaScript

console.log(`Thoughts tokens: ${interaction.usage.total_thought_tokens}`);
console.log(`Output tokens: ${interaction.usage.total_output_tokens}`);

Model pemikiran menghasilkan pemikiran lengkap untuk meningkatkan kualitas respons akhir, lalu menghasilkan ringkasan untuk memberikan pemahaman tentang proses pemikiran. Harga didasarkan pada token pemikiran penuh yang dibutuhkan model untuk dibuat, meskipun hanya ringkasan yang dihasilkan dari API.

Anda dapat mempelajari lebih lanjut token dalam panduan Penghitungan token.

Praktik terbaik

Gunakan model pemikiran secara efisien dengan mengikuti panduan berikut.

Tinjau penalaran: Analisis ringkasan pemikiran untuk memahami kegagalan dan meningkatkan kualitas perintah.
Mengontrol anggaran penalaran: Beri perintah pada model untuk berpikir lebih sedikit untuk output yang panjang guna menghemat token.
Tugas sederhana: Gunakan pemikiran minimal atau rendah untuk pengambilan atau klasifikasi fakta (misalnya, "Di mana DeepMind didirikan?").
Tugas moderasi: Gunakan pemikiran default untuk membandingkan konsep atau penalaran kreatif (misalnya, Bandingkan mobil listrik dan hybrid).
Tugas kompleks: Gunakan pemikiran maksimal untuk coding tingkat lanjut, matematika, atau perencanaan multi-langkah (misalnya, Selesaikan soal matematika AIME).
