voyage-3.5
Voyage 3.5 updates voyage-3 with revised training data and distillation. Voyage reports the same model size as its predecessor.
Model design
Training draws on voyage-3-large and reranking models. The release adds flexible dimensions and quantized output to this general model tier. It retains a 32,000-token input limit.voyage-3.5 and voyage-3.5-lite
Practical use
Practical guidance. For an existing voyage-3 index, measure whether improved retrieval justifies rebuilding document vectors. Keep a fixed set of real queries and compare missed evidence, not only an aggregate leaderboard score.
