Generate embeddings for text input

Generate vector embeddings from input text.

This endpoint converts text into high-dimensional vector representations that capture semantic meaning. These embeddings preserve semantic relationships between texts and can be used for various machine learning tasks.

Notes:

• Empty strings or arrays are not accepted
• Results include index numbers for mapping back to original inputs
• All embeddings are generated as query vectors. If the embeddings have two modes (e.g., query and document), this endpoint only returns query vectors.
