Examples
100k vectors at 768 dimensions (float32)
{
"vector_count": 100000,
"dimension": 768,
"data_type": "float32"
}Expected output
307.2 MB
50k vectors at 2048 dimensions (float16, compressed)
{
"vector_count": 50000,
"dimension": 2048,
"data_type": "float16",
"compression": true
}Expected output
102.4 MB (compressed)
How it works
The calculator estimates storage by multiplying the number of vectors by the embedding dimension and the bytes per value (4 for float32, 2 for float16/bfloat16). Compression reduces storage by 50% if enabled.
