input is one string or a list of strings. Match each vector to its input by data[].index.
Vector lengths differ by model: 1536 for
text-embedding-3-small, 3072 for gemini-embedding-001, 4096 for qwen3-embedding-8b. Compare vectors only from the same model and the same dimensions.
NagaAI charges embeddings per input token at pricing.per_token.
