multilingual-e5-base — GGUF (Q8_0)

GGUF build of intfloat/multilingual-e5-base — a multilingual XLM-RoBERTa embedding model (278M params, 768 dimensions, 100 languages, passage:/query: asymmetric prefixes).

Built from first-party intfloat safetensors, because no reputable quantizer publishes this model — this repo exists so downstream projects (vectorlink, TerminusDB) have an auditable supply chain rather than pulling a random community upload.

Provenance

Step	Tool	Pin
Source weights	intfloat/multilingual-e5-base	commit d128750597153bb5987e10b1c3493a34e5a4502a
Conversion	llama.cpp convert_hf_to_gguf.py	release b6987
Quantization	llama-quantize → Q8_0	llama.cpp 0.6.0

Build script: make-multilingual-e5-base-gguf.sh — downloads pinned first-party weights, verifies the safetensors SHA-256, converts, asserts mean pooling + 768-dim in the GGUF metadata, then quantizes.

Verification

Same probe text, cosine similarity vs the original safetensors weights (f16 conversion): 0.9998. Mean pooling, passage:/query: prefixes applied by the caller per E5 convention.

Usage (Ollama)

ollama pull hf.co/vectorlink/multilingual-e5-base-GGUF:Q8_0
ollama cp hf.co/vectorlink/multilingual-e5-base-GGUF:Q8_0 multilingual-e5-base
curl localhost:11434/api/embed -d '{"model":"multilingual-e5-base","input":"query: test"}'  # → 768-dim
