This version

This model was converted to a 8-bit GGUF format (q8_0) from Alibaba-NLP/gte-Qwen2-1.5B-instruct using llama-quantize built from llama.cpp.

Custom conversion script settings:

  "gte-Qwen2-1.5B-instruct": {
    "model_name": "gte-Qwen2-1.5B-instruct", 
    "hq_quant_type": "f32",
    "final_quant_type": "q8_0",
    "produce_final_quant": true,
    "parts_num": 2,
    "max_shard_size_gb": 4,
    "numexpr_max_thread": 8
    }

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.

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 

# 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-Q8_0 --hf-file gte-Qwen2-1.5B-instruct-Q8_0-00001-of-00002.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-Q8_0/gte-Qwen2-1.5B-instruct-Q8_0-00001-of-00002.gguf --n-gpu-layers 0 --ctx-size 131072 --embeddings
