Anda dapat membuat agen dengan model pondasi apa pun. Saat ini, beberapa model yang ditawarkan dioptimalkan dengan prompts/parsers fine-tuned untuk diintegrasikan dengan arsitektur agen. Seiring waktu, kami berencana untuk menawarkan pengoptimalan untuk semua model yang ditawarkan. ## Melihat model yang belum dioptimalkan untuk Amazon Bedrock Agents Anda dapat melihat daftar model yang belum dioptimalkan untuk Agen di konsol Amazon Bedrock saat Anda membuat agen baru atau memperbarui agen. **Untuk melihat model yang tidak dioptimalkan untuk agen Amazon Bedrock** 1. Jika Anda belum berada di agen builder, lakukan hal berikut: 1. Masuk ke Konsol Manajemen AWS dengan identitas IAM yang memiliki izin untuk menggunakan konsol Amazon Bedrock. Kemudian, buka konsol Amazon Bedrock di [https://console.aws.amazon.com/bedrock](https://console.aws.amazon.com/bedrock). 1. Pilih **Agen** dari panel navigasi kiri. Kemudian, pilih agen di bagian **Agen**. 1. Pilih **Edit di Agen builder**. 1. Di bagian **Pilih model**, pilih ikon pensil. 1. Secara default, model yang dioptimalkan untuk agen ditampilkan. Untuk melihat semua model yang didukung oleh Amazon Bedrock Agents, hapus Agen **Bedrock** dioptimalkan. ![\[Lihat semua model foundation yang didukung oleh Amazon Bedrock Agents.\]](http://docs.aws.amazon.com/id_id/bedrock/latest/userguide/images/agents/agents-optimized-model-selection.png) ## Contoh untuk menggunakan model yang belum dioptimalkan untuk Amazon Bedrock Agents Jika Anda telah memilih model yang pengoptimalannya belum tersedia, Anda dapat mengganti prompt untuk mengekstrak respons yang lebih baik, dan jika perlu, ganti parser. Untuk informasi selengkapnya tentang petunjuk utama, lihat. [Tulis fungsi Lambda parser khusus di Amazon Bedrock Agents](lambda-parser.md) Lihat [contoh kode ini](https://github.com/awslabs/amazon-bedrock-agent-samples/tree/main/examples/agents/agent_with_models_not_yet_optimized_for_bedrock_agents) untuk referensi. Bagian berikut memberikan contoh kode untuk menggunakan alat dengan model yang belum dioptimalkan untuk Amazon Bedrock Agents. Anda dapat menggunakan Amazon Bedrock API untuk memberikan akses model ke alat yang dapat membantunya menghasilkan respons untuk pesan yang Anda kirim ke model. Misalnya, Anda mungkin memiliki aplikasi obrolan yang memungkinkan pengguna mengetahui lagu paling populer yang diputar di stasiun radio. Untuk menjawab permintaan lagu paling populer, model membutuhkan alat yang dapat menanyakan dan mengembalikan informasi lagu. Untuk informasi selengkapnya tentang penggunaan alat, lihat[Gunakan alat untuk menyelesaikan respons model Amazon Bedrock](tool-use.md). ### Menggunakan alat dengan model yang mendukung penggunaan alat asli Model Amazon Bedrock tertentu, meskipun belum dioptimalkan untuk Agen Bedrock Amazon, hadir dengan kemampuan penggunaan alat bawaan. Untuk model seperti itu, Anda dapat meningkatkan kinerja dengan mengganti prompt dan parser default sesuai kebutuhan. Dengan menyesuaikan permintaan khusus untuk model yang Anda pilih, Anda dapat meningkatkan kualitas respons dan menyelesaikan ketidakkonsistenan apa pun dengan konvensi permintaan khusus model. **Contoh: Mengganti prompt dengan Mistral Large** Amazon Bedrock Agents mendukung Mistral Large model yang memiliki kemampuan penggunaan alat. Namun, karena konvensi yang diminta Mistral Large berbeda dariClaude, prompt dan parser tidak dioptimalkan. **Contoh prompt** Contoh berikut mengubah prompt untuk memberikan pemanggilan alat dan penguraian kutipan basis pengetahuan yang Mistral Large lebih baik. ``` { "system": " $instruction$ You are a helpful assistant with tool calling capabilities. Try to answer questions with the tools available to you. When responding to user queries with a tool call, please respond with a JSON for a function call with its proper arguments that best answers the given prompt. IF YOU ARE MAKING A TOOL CALL, SET THE STOP REASON AS \"tool_use\". When you receive a tool call response, use the output to format an answer to the original user question. Provide your final answer to the user's question within xml tags. These guidelines are to be followed when using the provided by a know base search. - IF THE SEARCH RESULTS CONTAIN THE WORD \"operator\", REPLACE IT WITH \"processor\". - Always collate the sources and add them in your in the format: $ANSWER$ $SOURCE$ $prompt_session_attributes$ ", "messages": [ { "role": "user", "content": [ { "text": "$question$" } ] }, { "role": "assistant", "content": [ { "text": "$conversation_history$" } ] } ] } ``` **Contoh parser** Jika Anda menyertakan instruksi khusus dalam prompt yang dioptimalkan, maka Anda perlu menyediakan implementasi parser untuk mengurai keluaran model setelah instruksi tersebut. ``` { "modelInvocationInput": { "inferenceConfiguration": { "maximumLength": 2048, "stopSequences": [ "" ], "temperature": 0, "topK": 250, "topP": 1 }, "text": "{ \"system\":\" You are an agent who manages policy engine violations and answer queries related to team level risks. Users interact with you to get required violations under various hierarchies and aliases, and acknowledge them, if required, on time. You are a helpful assistant with tool calling capabilities.

When responding to user queries with a tool call, please respond with a JSON for a function call with its proper arguments that best answers the given prompt. IF YOU ARE MAKING A TOOL CALL, SET THE STOP REASON AS \\\"tool_use\\\". When you receive a tool call response, use the output to format an answer to the original user question. Provide your final answer to the user's question within xml tags. \", \"messages\": [ { \"content\": \"[{text=Find policy violations for ********}]\", \"role\":\"user\" }, { \"content\": \"[{toolUse={input={endDate=2022-12-31, alias={alias=*******}, startDate=2022-01-01}, name=get__PolicyEngineActions__GetPolicyViolations}}]\", \"role\":\"assistant\" }, { \"content\":\"[{toolResult={toolUseId=tooluse_2_2YEPJBQi2CSOVABmf7Og,content=[ \\\"creationDate\\\": \\\"2023-06-01T09:30:00Z\\\", \\\"riskLevel\\\": \\\"High\\\", \\\"policyId\\\": \\\"POL-001\\\", \\\"policyUrl\\\": \\\"https://example.com/policies/POL-001\\\", \\\"referenceUrl\\\": \\\"https://example.com/violations/POL-001\\\"} ], status=success}}]\", \"role\":\"user\" } ] }", "traceId": "5a39a0de-9025-4450-bd5a-46bc6bf5a920-1", "type": "ORCHESTRATION" }, "observation": [ "..." ] } ``` Perubahan yang diminta dalam kode contoh menyebabkan model memuntahkan jejak yang secara khusus menyebutkan tool\$1use sebagai alasan berhenti. Karena ini adalah standar untuk parser default, tidak ada perubahan lebih lanjut yang diperlukan, tetapi jika Anda menambahkan instruksi spesifik baru, maka parser perlu ditulis untuk menangani perubahan. ### Menggunakan alat dengan model yang tidak mendukung penggunaan alat asli Biasanya untuk model agen, beberapa penyedia model mengaktifkan dukungan penggunaan alat. Jika penggunaan alat tidak didukung untuk model yang Anda pilih, sebaiknya Anda mengevaluasi kembali apakah model ini adalah model yang tepat untuk usecase agen Anda. Jika Anda ingin melanjutkan dengan model yang Anda pilih, Anda dapat menambahkan alat ke model dengan mendefinisikan alat di prompt dan kemudian menulis parser khusus untuk mengurai respons model untuk pemanggilan alat. **Contoh: Mengganti prompt dengan DeepSeek R1** Amazon Bedrock Agents mendukung DeepSeek R1 model yang tidak mendukung penggunaan alat. Lihat dokumentasi [DeepSeek-R1](https://github.com/deepseek-ai/DeepSeek-R1) untuk informasi lebih lanjut. Contoh kode berikut mendefinisikan dan memanggil alat yang membantu pengguna mencari dan memesan penerbangan untuk tanggal dan waktu yang ditentukan. Contoh kode menunjukkan cara menggunakan prompt khusus dan mengganti parser. **Contoh prompt** Contoh berikut memanggil alat yang mengumpulkan informasi penerbangan dari pengguna dan menjawab pertanyaan pengguna. Contoh mengasumsikan bahwa grup tindakan dibuat untuk agen yang mengirimkan respons kembali ke pengguna. ``` { "system": "To book a flight, you should know the origin and destination airports and the day and time the flight takes off. If anything among date and time is not provided ask the User for more details and then call the provided tools. You have been provided with a set of tools to answer the user's question. You must call the tools in the format below: $TOOL_NAME <$PARAMETER_NAME>$PARAMETER_VALUE ...
