This model was converted from the 32-bit original safetensors format to a 16-bit GGUF format (f16) from Alibaba-NLP/gte-Qwen2-1.5B-instruct using llama-quantize built from llama.cpp.

Custom conversion script settings:

Please refer to the original model card for more details on the unquantized model, including its metrics, which may be different (typically slightly worse) for this quantized version.

gte-Qwen2-1.5B-instruct

gte-Qwen2-1.5B-instruct is the latest model in the gte (General Text Embedding) model family. The model is built on Qwen2-1.5B LLM model and use the same training data and strategies as the gte-Qwen2-7B-instruct model.

The model incorporates several key advancements:

Integration of bidirectional attention mechanisms, enriching its contextual understanding.
Instruction tuning, applied solely on the query side for streamlined efficiency
Comprehensive training across a vast, multilingual text corpus spanning diverse domains and scenarios. This training leverages both weakly supervised and supervised data, ensuring the model's applicability across numerous languages and a wide array of downstream tasks.

Usage

Sentence Transformers

Transformers

Inference

Using `llama.cpp` to get embeddings in CPU and/or GPU

First build or install llama-server binary from llama.cpp, preferably with GPU support.

CLI

Server

bash

# using remote HF repo address (with model file(s) to be downloaded and cached locally)
$ llama-server --hf-repo mirekphd/gte-Qwen2-1.5B-instruct-F16 --hf-file gte-Qwen2-1.5B-instruct-F16.gguf --n-gpu-layers 0 --ctx-size 131072 --embeddings

# using a previously downloaded local model file(s)
$ llama-server --model <path-to-hf-models>/mirekphd/gte-Qwen2-1.5B-instruct-F16/gte-Qwen2-1.5B-instruct-F16.gguf --n-gpu-layers 0 --ctx-size 131072 --embeddings
