text-embedding-3-* hỗ trợ tham số dimensions, cho phép bạn rút ngắn vector embedding mà không làm giảm đáng kể độ chính xác. Điều này có thể giảm chi phí lưu trữ tới 75% trong khi vẫn giữ lại phần lớn thông tin ngữ nghĩa.input. Cách này hiệu quả hơn đáng kể so với việc tạo từng request riêng cho mỗi đoạn văn bản.Bearer token authentication. Use your CometAPI key.
The embedding model to use. See the Models page for current embedding model IDs.
"text-embedding-3-small"
The text to embed. Can be a single string, an array of strings, or an array of token arrays. Each input must not exceed the model's maximum token limit (8,191 tokens for text-embedding-3-* models).
The format of the returned embedding vectors. float returns an array of floating-point numbers. base64 returns a base64-encoded string representation, which can reduce response size for large batches.
float, base64 The number of dimensions for the output embedding vector. Only supported by text-embedding-3-* models. Reducing dimensions can lower storage costs while maintaining most of the embedding's utility.
x >= 1A unique identifier for your end-user, which can help monitor and detect abuse.
A list of embedding vectors for the input text(s).
The object type, always list.
list "list"
An array of embedding objects, one per input text. When multiple inputs are provided, results are returned in the same order as the input.
