Neither page mentions that Notion acquired ZeroEntropy on 24 July 2026, that signups closed that day, or that API support ended on 4 September, after which the vendor's own migration guide says calls stop working. An agent budgeting from the pricing page would be pricing a service that no longer exists. The live option is the weights, announced as Apache 2.0 on Hugging Face (the zerank-2 licence is unconfirmed), where the cost is a GPU, and the guide points to Baseten or Modal. The hosted alternatives it names are Cohere and Voyage. One because the rate card is advertised for something that isn't for sale."
