REASONING

Not published

Only provider-documented reasoning controls are shown; missing controls remain unpublished rather than inferred.

INPUT

text

Input modalities come from the cited official model documentation.

OUTPUT

ranking

Output modality and output-limit claims remain separate so an undocumented token cap is not guessed.

PRICING STATUS

No direct Standard price published.

SXF preserves the provider-published native billing basis. Only calculator-eligible generative token models enter token-cost arithmetic; specialist units and input-only embeddings remain visible without forced conversion.

CAVEATS

What the source record does not assume.

Cohere documents a 32,768-token context length for Rerank 4.0.

The API reports billed search_units and Cohere states Rerank is priced by quantity of searches.

No current public PAYG numeric rate for Rerank 4 Pro was verified in the cited official pricing documentation, so pricing remains not-published rather than inheriting an older Rerank price.
