Embeddings

voyage-code-4 is a code embedding model from Voyage AI, a MongoDB company. It turns code and technical text into vectors so a coding agent or search tool can find the right functions, files and snippets in a large codebase. Embeddings come in 2048, 1024, 512 or 256 dimensions with several quantisation options, so you can trade a little accuracy for much smaller indexes.

The model handles up to 32K tokens of input per request. Through Hormouz it is served behind an OpenAI-compatible embeddings API: point your base URL at Hormouz and drop in a Hormouz key. Pricing is usage-based at $0.12 per million input tokens. There is no fixed monthly fee.

Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
