Contoh Amazon Bedrock Runtime menggunakan AWS SDK for .NET

Contoh kode berikut menunjukkan cara melakukan tindakan dan mengimplementasikan skenario umum dengan menggunakan Runtime AWS SDK for .NET with Amazon Bedrock.

Skenario adalah contoh kode yang menunjukkan kepada Anda bagaimana menyelesaikan tugas tertentu dengan memanggil beberapa fungsi dalam layanan atau dikombinasikan dengan yang lain Layanan AWS.

Setiap contoh menyertakan tautan ke kode sumber lengkap, di mana Anda dapat menemukan instruksi tentang cara mengatur dan menjalankan kode dalam konteks.

Skenario

Contoh kode berikut menunjukkan cara membuat taman bermain untuk berinteraksi dengan model dasar Amazon Bedrock melalui modalitas yang berbeda.

AWS SDK for .NET

. NETFoundation Model (FM) Playground adalah sebuah. NETMAUIContoh aplikasi Blazor yang menampilkan cara menggunakan Amazon Bedrock dari kode C#. Contoh ini menunjukkan caranya. NETdan pengembang C# dapat menggunakan Amazon Bedrock untuk membangun aplikasi berkemampuan AI generatif. Anda dapat menguji dan berinteraksi dengan model yayasan Amazon Bedrock dengan menggunakan empat taman bermain berikut:

  • Taman bermain teks.

  • Taman bermain obrolan.

  • Taman bermain obrolan suara.

  • Taman bermain gambar.

Contoh ini juga mencantumkan dan menampilkan model fondasi yang dapat Anda akses dan karakteristiknya. Untuk kode sumber dan petunjuk penerapan, lihat proyek di GitHub.

Layanan yang digunakan dalam contoh ini
