Mistral AIParameter dan inferensi 2 (24,07) besar

Penyelesaian Mistral AI obrolan API memungkinkan Anda membuat aplikasi percakapan. Anda juga dapat menggunakan Amazon Bedrock Converse API dengan model ini. Anda dapat menggunakan alat untuk melakukan panggilan fungsi.

Tip

Anda dapat menggunakan penyelesaian Mistral AI obrolan API dengan operasi inferensi dasar (InvokeModelatau InvokeModelWithResponseStream). Namun, kami menyarankan Anda menggunakan Converse API untuk mengimplementasikan pesan dalam aplikasi Anda. Converse API menyediakan serangkaian parameter terpadu yang bekerja di semua model yang mendukung pesan. Untuk informasi selengkapnya, lihat Lakukan percakapan dengan Converse.

Mistral AImodel tersedia di bawah lisensi Apache 2.0. Untuk informasi selengkapnya tentang penggunaan Mistral AI model, lihat Mistral AIdokumentasi.

Model yang didukung

Anda dapat menggunakan Mistral AI model berikut dengan contoh kode di halaman ini..

• Mistral Large 2 (24.07)

Anda memerlukan ID model untuk model yang ingin Anda gunakan. Untuk mendapatkan ID model, lihatModel Amazon Bedrock IDs.
