Is Qwen2.5-Coder-0.5B-Instruct or embeddinggemma-300m smaller?

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

Which uses less memory at long context?

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

Model comparison

Qwen2.5-Coder-0.5B-Instruct vs embeddinggemma-300m

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