            # 🌍 Tiếng Việt - Dự án Đánh giá Prompt Đa ngôn ngữ

            Hugging Face và @argilla đang phát triển dự án [Dự án Đánh giá prompt Đa ngôn ngữ](https://github.com/huggingface/data-is-better-together/tree/main/prompt_translation). Đây là một chuẩn mực mở đa ngôn ngữ để đánh giá các mô hình ngôn ngữ, và tất nhiên, cũng dành cho tiếng Việt.

            ## Mục tiêu là dịch 500 Prompts
            
            Và như mọi khi: cần có dữ liệu cho việc đó! Cộng đồng đã chọn ra 500 prompt tốt nhất sẽ tạo nên chuẩn mực đánh giá. Bằng tiếng Anh, tất nhiên.
            
            **Đó là lý do chúng mình cần sự giúp đỡ của bạn**: nếu chúng ta cùng nhau dịch 500 prompts, chúng mình có thể thêm Tiếng Việt vào bảng xếp hạng.

            ## Cách tham gia
            Truy cập vào [AI-Vietnam/prompt-translation-for-vie](https://huggingface.co/spaces/AI-Vietnam/prompt-translation-for-vie), đăng nhập hoặc tạo một tài khoản Hugging Face, và bạn có thể bắt đầu.
            
            Cảm ơn các bạn rất nhiều! Bên cạnh đó, chúng mình đã dùng AI để chuẩn bị sẵn một đề xuất dịch giúp tăng tốc quá trình dịch thuật.
