Halaman ini menjelaskan cara menyiapkan integrasi antara AlloyDB untuk PostgreSQL dan Vertex AI, sehingga Anda dapat menerapkan kueri ke model bahasa besar (LLM) yang disimpan di cloud ke data Anda.
Petunjuk ini khusus untuk penggunaan AlloyDB, dan bukan
AlloyDB Omni. Untuk mengintegrasikan penginstalan lokal
AlloyDB Omni menggunakan Vertex AI, lihat Menginstal
AlloyDB Omni dengan AlloyDB AI.
Untuk mengetahui informasi selengkapnya tentang Vertex AI, lihat Pengantar Vertex AI.
