Default output: 1,024 dimensions.

Listed sizes: 2,048, 1,024, 512 and 256.

Voyage AI documents shorter output vectors for this model (Matryoshka-style), so you can store smaller embeddings by asking for fewer dimensions instead of re-embedding with another model.

result = vo.contextualized_embed(
    model="voyage-context-4",
    inputs=[
        "What was the revenue growth for Leafy Inc. in Q2 2024?",
        "What changed in Greenery Corp. between Q1 and Q2 2024?",
    ],
    input_type="query",
)
