Custom Instructions adalah fitur ChatGPT yang memungkinkan kamu mengatur preferensi dan instruksi permanen yang akan diterapkan pada semua percakapan, tanpa perlu mengulang konteks setiap kali.
Diluncurkan Juli 2023 untuk Plus users dan kemudian tersedia untuk semua pengguna, fitur ini mengubah ChatGPT dari assistant generik menjadi AI personal yang disesuaikan dengan kebutuhan kamu.
Manfaat utamanya adalah tidak perlu repeat context, ChatGPT ingat preferensi di setiap chat, konsistensi output tone/format/style selalu sesuai, dan efisiensi waktu skip repetitive instructions.
Penting diketahui perbedaan dengan Memory: Custom Instructions adalah manual, permanent, user-defined preferences, sementara Memory adalah automatic, dynamic, AI-learned dari conversation.
Cara Aktivasi Custom Instructions
Langkah 1: Buka Settings — Klik nama akun atau profile picture di pojok, pilih “Settings” dari dropdown menu.
Langkah 2: Masuk Personalization — Di menu Settings, klik tab “Personalization” dan pilih “Custom Instructions”.
Langkah 3: Aktifkan Toggle — Jika belum aktif, geser toggle “Enable for new chats” dan dua input fields akan muncul.
Langkah 4: Isi Dua Field — Field 1 “What would you like ChatGPT to know about you?” adalah informasi tentang siapa kamu: role, profession, interests. Contoh: “I’m a software engineer specializing in Python. I run a tech blog. I’m passionate about clean code.”
Field 2 “How would you like ChatGPT to respond?” adalah preferensi output style: tone, format, length, structure. Contoh: “Be concise. Use bullet points. Avoid jargon. Provide code examples.”
Langkah 5: Save — Klik “Save” untuk apply ke semua future conversations dan Custom Instructions aktif untuk all new chats.
Custom Instructions vs Memory
| Aspek | Custom Instructions | Memory |
| Input | Manual (user-defined) | Automatic (AI-learned) |
| Scope | Permanent, explicit preferences | Dynamic, contextual details |
| Update | Manual edit required | Self-updating via conversation |
| Best For | Broad control, style, role | Specific facts, recent context |
| Examples | “I’m a developer”, “Use bullet points” | “Working on Project X”, “Prefers coffee” |
Kapan gunakan Custom Instructions: permanent preferences role/profession/output style yang tidak berubah, broad guidelines tone/format/length konsisten.
Kapan gunakan Memory: evolving context project details/preferences yang berubah, conversational nudges contextual reminders.
Best practice adalah Custom Instructions untuk core unchanging info (role, style) dan Memory untuk dynamic details (current projects, temporary preferences).
4 Langkah Membuat Custom Instructions Efektif
Langkah 1: Identifikasi Masalah — Apa yang repetitive dalam prompt kamu? Generic responses yang tidak relevan? Tone atau format yang tidak sesuai?
Langkah 2: Tentukan Kebutuhan — Role: Software engineer, Content creator, Researcher? Output style: Concise atau detailed, Technical atau casual? Format: Bullet points, paragraphs, code blocks?
Langkah 3: Buat Persona — Definisikan siapa kamu untuk ChatGPT dengan job, industry, goals, constraints.
Langkah 4: Specify Response Style — Tone professional/friendly/academic? Structure headings/bullets/TL;DR? Length short atau comprehensive? Language English/Indonesia/bilingual?

Best Practices
Do’s:
Be specific—vague instructions tidak efektif. Gunakan structure dengan headings, bullets, short imperative directives. Provide examples dari output format yang diinginkan. Keep it concise—limit 1-2 pages atau ~1,000 lines max karena shorter = higher compliance. Iterate dengan test dan refine berdasarkan results.
Don’ts:
Jangan overload dengan terlalu banyak instructions—diluted effectiveness. Avoid narrative paragraphs; gunakan bullet points bukan long prose. Don’t include temporary info—current project details belong in Memory, bukan Custom Instructions.
Advanced Tips
Multiple Personas: Create berbeda Custom Instructions untuk different tasks dan remove saat switch context.
Combine dengan Memory: Instructions untuk permanent style, Memory untuk dynamic facts.
Test dan Refine: Observe mana instructions yang ChatGPT follow dan iterate one instruction saat.
Use Temporary Chat: Disable Custom Instructions untuk one-off queries jika butuh berbeda approach.
Kesimpulannya
Custom Instructions mengubah ChatGPT dari assistant generik menjadi AI personal yang memahami role, preferences, dan output style kamu.
Dengan mengisi dua field—“About You” dan “Response Style”—kamu dapat konsistensi tanpa repeat instructions setiap chat.
Key takeaways: Akses via Settings → Personalization → Custom Instructions; isi dua fields dengan about you plus response preferences; best untuk permanent preferences role/tone/format; combine dengan Memory untuk maximum personalization; start small dengan 10-20 focused instructions lalu iterate.
