vespa-onnx-intfloat-multilingual-e5-large

Converted intfloat/multilingual-e5-large model in onnx fp16/int8 format for use with Vespa Embedding.

• intfloat-multilingual-e5-large_fp16.onnx (fp16)
• intfloat-multilingual-e5-large_quantized.onnx (int8 quantized)

The model was quantized using the optimum toolkit.

Example of vespa services.xml:

Notice: FP16 works well with Vespa versions 8.325.46 and above.
