Amazon Health AI vs Cohere Embed v4

Pricing, capabilities and platforms side by side. Prices are as of the "Pricing checked" date in the table.

Amazon Health AI

Amazon Health AI is the agentic assistant on Amazon.com, the Amazon app, and One Medical: it answers health questions, interprets records and labs when you grant access through health information exchange, books One Medical visits, and can start prescription renewals through Amazon Pharmacy. Prime members in the U.S. get an introductory bundle of Direct Message Care for 30+ common conditions; everyone else can chat for free and pays per provider visit. It is not a specialist clinic, it does not write treatment plans on its own, and rollout is U.S.-only.

Cohere Embed v4

Cohere Embed v4 transforms text, images, and mixed content into unified vector representations for semantic search, RAG, document clustering, and similarity matching. The model supports 1,536-dimensional embeddings with flexible compression via Matryoshka embeddings (256, 512, 1024, 1536 dimensions). Priced at $0.12/1M text tokens and $0.47/1M image tokens, it delivers multimodal capabilities competitive with text-only alternatives. The API supports batch processing up to 128,000 tokens per request with asymmetric search optimization. Limitation: incompatible with v3 embeddings; corpus re-embedding required for upgrades.
