Cross-model retrieval tested: 0.6B querying a 9B index closes half the gap at no latency cost

This post highlights cross-model retrieval enabled by the shared embedding space: using the 0.6B model to query a 9B index beats the 0.6B index with no query-time cost. The 9B for querying remains strongest, but the smaller model closes roughly half the gap — a flexible accuracy/latency tradeoff for production.
