Voyage Code 4
Available nowHelp people and coding assistants find the source code behind a natural-language question.
What it does
Voyage Code 4 is specialized for code retrieval and coding-agent use cases. It connects a description of a task or behavior with relevant source code, helping a developer find the files or functions they should inspect.
This is useful when searching by meaning is more productive than searching for an exact symbol. embeddings can retrieve candidate code passages for an assistant, documentation tool or developer search interface. The model provides selectable vector sizes and long source context.
Where it helps
Repository search
Find the implementation related to a question such as how refunds are handled.
Coding assistants
Retrieve relevant code before asking an assistant to explain or modify it.
Developer onboarding
Connect a description of a product behavior to the code responsible for it.
When to choose it
Consider it when source code is the main content in your search collection. Compare it with a general embedding model on real developer questions to confirm the specialist adds value.
It retrieves related code; it does not run code, validate correctness or fix vulnerabilities. Keep useful boundaries and file context in indexed passages.
