Decision models show embedding models are ripe for disruption as the Pareto frontier of model form factors stays unexplored

Using @typesafeai's decision models as an example, the author argues the Pareto frontier of model form factors is largely unexplored: deliberate tradeoffs for specific capabilities can yield order-of-magnitude gains in speed, throughput, and reliability, reopening use cases like computer use and production classification.

Embedding models, he contends, are ready for disruption—they offer pre-computable, compact representations with O(N) storage and O(log N) interaction, and can even be initialized from (M)LLMs. But even instruction-tuned embeddings leave much expressivity unused at the query interface. There's no reason intelligence can't be shifted into retrieval the way it has been into classification.
