Rerank V4.0 Fast accepts text as listed input formats. Listed output formats include text. Image or audio input support does not imply image or audio generation. Check the chosen provider’s Rerank V4.0 Fast documentation for supported file types and request formats.
Rerank V4.0 Fast has a listed context window of 32K tokens. Tokens are small pieces of content rather than a word count. Instructions, conversation history, and other inputs use context space, and the response also needs room. The maximum output length for Rerank V4.0 Fast may be smaller than the context window and can vary by provider.
Neither reasoning nor tool calling support is listed for Rerank V4.0 Fast. Reasoning enables additional processing for complex problems. Tool calling allows a model to request functions that your app executes. Check the chosen provider’s documentation for capability availability and setup.
