Integrasi Multi-Modal

Aplikasi multi-modal semakin penting dalam AI, membolehkan interaksi yang lebih kaya dan tugasan yang lebih kompleks. Model Context Protocol (MCP) menyediakan rangka kerja untuk membina aplikasi multi-modal yang boleh mengendalikan pelbagai jenis data, seperti teks, imej, dan audio.

MCP menyokong bukan sahaja interaksi berasaskan teks tetapi juga keupayaan multi-modal, membolehkan model bekerja dengan imej, audio, dan jenis data lain.

Pengenalan

Dalam pelajaran ini, anda akan belajar cara membina aplikasi multi-modal.

Objektif Pembelajaran

Menjelang akhir pelajaran ini, anda akan dapat:

  • Memahami pilihan multi-modal
  • Melaksanakan aplikasi multi-modal.

Seni Bina untuk Sokongan Multi-Modal

Pelaksanaan MCP multi-modal biasanya melibatkan:

  • Parser Khusus Modal: Komponen yang menukar pelbagai jenis media ke dalam format yang boleh diproses oleh model.
  • Alat Khusus Modal: Alat khas yang direka untuk mengendalikan modaliti tertentu (analisis imej, pemprosesan audio)
  • Pengurusan Konteks Bersatu: Sistem untuk mengekalkan konteks merentasi modaliti yang berbeza
  • Penjanaan Respons: Keupayaan untuk menghasilkan respons yang mungkin merangkumi pelbagai modaliti.

Contoh Multi-Modal: Analisis Imej

Dalam contoh di bawah, kita akan menganalisis imej dan mengekstrak maklumat.

Pelaksanaan C#

            return await httpClient.GetByteArrayAsync(url);
        }
    }
    
    // Multi-modal MCP server with image and text processing
    public class MultiModalMcpServer
    {
        public static async Task Main(string[] args)
        {
            // Create an MCP server
            var server = new McpServer(
                name: "Multi-Modal MCP Server",
                version: "1.0.0"
            );
            
            // Configure server for multi-modal support
            var serverOptions = new McpServerOptions
            {
                MaxRequestSize = 10 * 1024 * 1024, // 10MB for larger payloads like images
                SupportedContentTypes = new[]
                {
                    "image/jpeg",
                    "image/png",
                    "text/plain",
                    "application/json"
                }

            // Create image analysis service
            var imageService = new ComputerVisionService();
            
            // Register image analysis tools
            server.AddTool(new ImageAnalysisTool(imageService));
            
            // Register a text-to-image tool
            services.AddMcpTool<TextAnalysisTool>();
            services.AddMcpTool<ImageAnalysisTool>();
            services.AddMcpTool<DocumentGenerationTool>(); // Tool that can generate documents with text and images
        }
    }
}

Dalam contoh sebelum ini, kami telah:

  • Mencipta ImageAnalysisTool yang boleh menganalisis imej menggunakan IImageAnalysisService hipotetikal.
  • Mengkonfigurasi pelayan MCP untuk mengendalikan permintaan yang lebih besar dan menyokong jenis kandungan imej.
  • Mendaftar alat analisis imej dengan pelayan.
  • Melaksanakan kaedah untuk memuat turun imej dari URL dan menganalisisnya berdasarkan jenis yang diminta (objek, teks, wajah, dan lain-lain).
  • Mengembalikan hasil berstruktur dalam format yang mematuhi spesifikasi MCP.
