}'Kunavo vs memanggil Anthropic langsung
Model Claude Opus 5 Fast dan responsnya sama persis. Yang diubah gateway adalah akun, SDK, dan tagihan — ini perbandingan jujurnya.
| Kunavo | Anthropic langsung | |
|---|---|---|
| Harga (per 1M tokens) | $7.00 / $35.00 (−30%) | $10.00 / $50.00 |
| Akun | Satu akun Kunavo, kunci dalam 2 menit, isi ulang minimum $5 | Akun Anthropic beserta pengaturan penagihannya sendiri |
| SDK | Tetap pakai OpenAI SDK — ganti base_url, isi model dengan "claude-opus-5-fast" | SDK milik Anthropic, atau lapisan kompatibel-OpenAI bila tersedia |
| Kunci yang sama juga menjangkau | Claude, Gemini, GPT plus model gambar, video, dan audio | Hanya katalog Anthropic sendiri |
| Penagihan | Satu saldo Stripe, bayar sesuai pemakaian, tidak pernah hangus; permintaan gagal tidak ditagih | Faktur terpisah untuk tiap penyedia |
| Batas laju | Kapasitas gateway bersama, tanpa batas kontraktual per akun | Batas tier Anthropic sendiri, dinaikkan lewat riwayat pemakaian atau kontrak |
Pilih Anthropic langsung bila Anda butuh batas laju kontraktual, SLA enterprise, atau fitur khusus penyedia sejak hari pertama. Kunavo cocok bila Anda ingin satu kunci, satu tagihan, dan harga per token lebih rendah di semua penyedia.
