Voyage 3.5
Available nowKeep an existing Voyage 3.5 search index consistent while planning a measured upgrade.
What it does
Voyage 3.5 is an earlier general-purpose and multilingual retrieval model. It represents text for search and supports long source context with several vector sizes.
Voyage now recommends its newer models for new projects. This entry is retained because existing customers may already have document vectors built with 3.5. Keeping queries and documents in the same model’s space helps preserve a working search system while evaluating a migration.
Where it helps
Existing applications
Continue using the same model as an established Voyage 3.5 index.
Migration evaluation
Compare a newer model against known retrieval results.
Stable reference collections
Maintain a consistent representation while scheduling reindexing.
When to choose it
Choose it mainly when you already depend on Voyage 3.5 vectors. For a new application, evaluate the Voyage 4 family first, then decide using your collection and quality requirements.
This is a retained previous-generation option, not a claim that it is the newest model. An upgrade usually requires a deliberate reindexing plan.
