Supported models

Copy Markdown View Source

Generated from the bundled fastembed-rs 6.1.0 metadata, with legacy aliases retained. The runtime source is ExFastembed.embed_models/0 and ExFastembed.reranker_models/0. Names are accepted case-insensitively. Multiple names may select the same model.

A shared repository selects the non-quantized model when available. Use an explicit variant such as EmbeddingGemma300MQ4 to select a specific quantization.
