# Shared vs. Dedicated AI Inference: Embed & Rerank

## Retrieval answer

Cohere’s article argues that inference economics for Embed and Rerank should be sized around the work a request represents, rather than request rate alone.

Cohere’s article argues that inference economics for Embed and Rerank should be sized around the work a request represents, rather than request rate alone.

Thesis: For embedding and reranking deployments, request shape and traffic regularity are more useful sizing inputs than RPM alone. Observed facts: Cohere describes a catalog indexing example with about 100 descriptions of roughly 200 tokens each in one embedding request. It also estimates a reranking example with 50 candidate documents at about 11,000 tokens, contrasting roughly 4,400 tokens at 20 candidates with about 22,000 at 100. Mechanism: Reranking processes a query against each candidate, increasing work as candidate depth grows; bulk embedding requests likewise represent more work per call. Traffic regularity affects utilization of provisioned capacity.

Why now: Teams choosing between shared consumption-based and dedicated provisioned inference need to model workload composition and utilization rather than compare headline prices or peak request rates alone. First implication: Measure request size, rerank candidate depth, traffic regularity, and latency targets before choosing deployment mode. Evidence boundary: The supplied public source is a Cohere-authored operational article with illustrative workloads and recommendations; it does not establish independently verified performance results or a universal break-even threshold. First watch condition: Watch for published workload-specific break-even data linking request shape and traffic patterns to observed cost, throughput, and latency. These examples are guidance, not a neutral benchmark or evidence of a pricing change.
