Is embeddinggemma-300m-qat-q8_0-unquantized or KaLM-embedding-multilingual-mini-instruct-v2.5 smaller?

Both publish quantizations; compare the table for the exact sizes.

Which uses less memory at long context?

embeddinggemma-300m-qat-q8_0-unquantized — its KV cache at 32K context is 2.6x smaller, because of how its attention layers cache.

Model comparison

embeddinggemma-300m-qat-q8_0-unquantized vs KaLM-embedding-multilingual-mini-instruct-v2.5

These two publish different quantization sets; the table below has the exact sizes. At long context the gap widens: embeddinggemma-300m-qat-q8_0-unquantized's KV cache at 32K is 2.6× smaller, which usually matters more than the difference in weights.
