Model Versioning With Performance Improvements

Cohere's reranking model boosting search relevance 20-40%.

Unique: Multiple model versions (Fast, Pro variants) enable explicit accuracy-latency tradeoffs — teams can choose Fast for latency-sensitive applications or Pro for maximum accuracy. Continuous model improvements (Rerank 4 supersedes Rerank 3) ensure access to latest advances without code changes.

vs others: More flexible than static open-source models (e.g., BGE-Reranker) that require manual retraining for improvements; simpler than maintaining custom model variants because Cohere handles versioning and deprecation.
