Context caching

No model-specific cache eligibility, retained-prefix lifetime or discounted cache rate established in the reviewed documentation.

Embedding dimensions

Vector data types
float32, int8, uint8, binary, ubinarySource for Vector data types (opens in a new tab)
Document chunking
Automatic chunking defaults off. Default chunk size 512 tokens and overlap 0; overlap must be smaller than chunk size. Overlapping tokens are billed.Source for Document chunking (opens in a new tab)

Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

API model ID
voyage-context-3
Access
Voyage API key; account-specific usage and rate limits apply.
Regions
Contractual residency and serving-region guarantees require verification.
API endpoint URL
https://api.voyageai.com/v1/contextualizedembeddingsSource for API endpoint URL (opens in a new tab)
Total request input
120,000 tokens across the requestSource for Total request input (opens in a new tab)
Request limits
Up to 1,000 inputs and 16,000 chunks per request. Automatic chunking requires input_type=document and flat strings; do not combine it with client-side chunk_fn.Source for Request limits (opens in a new tab)

Rate conditions

  1. Input text tokens only, not generated output. Current pricing tables take precedence over inconsistent introductory free-credit examples. Older-model table entries have no free token allowance.

Data & enterprise terms

The FAQ describes an opt-out from storage and future training that enables zero-day retention on Voyage-hosted model API endpoints. This is an opt-out option, not a verified account default.

API model ID
voyage-context-3
Access
Public preview. Upload a JSONL file and create a project-scoped batch; model and parameters are fixed for the batch.
Regions
Contractual residency and serving-region guarantees require verification.
API endpoint URL
https://api.voyageai.com/v1/batchesSource for API endpoint URL (opens in a new tab)
Batch limits
100,000 inputs per batch; model-specific per-request limits still apply. Completion window: 12 hours.Source for Batch limits (opens in a new tab)
Usage metering
33% below standard endpoint pricing. Free token credits do not apply; file storage is billed separately.Source for Usage metering (opens in a new tab)
Batch target endpoint

Endpoint pricing has not been collected. Check the provider for applicable rates.

Data & enterprise terms

Files are retained for 30 days before automatic deletion. Storage costs $0.05 per GB per month. Do not apply online endpoint retention choices to batch files automatically.

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Inferred for this exact native release from provider API documentation and the provider-owned public repository inventory. Published tokenizer/configuration files are not model weights. The explicitly open-weight Voyage 4 Nano is excluded; no weight artifact for this identity was identified.
