BSC-LT/salamandra-7b-base-gptq

Salamandra-7b-gptq Model Card

This model is the gptq-quantized version of Salamandra-7b for speculative decoding.

The model weights are quantized from FP16 to W4A16 (4-bit weights and FP16 activations) using the GPTQ algorithm. Inferencing with this model can be done using VLLM.

Salamandra is a highly multilingual model pre-trained from scratch that comes in three different sizes — 2B, 7B and 40B parameters — with their respective base and instruction-tuned variants, promoted and financed by the Government of Catalonia through the Aina Project and the Ministerio para la Transformación Digital y de la Función Pública - Funded by EU – NextGenerationEU within the framework of ILENIA Project with reference 2022/TL22/00215337.

This model card corresponds to the gptq-quantized version of Salamandra-7b for speculative decoding.

The entire Salamandra family is released under a permissive Apache 2.0 license.

How to Use

The following example code works under Python 3.9.16, vllm==0.6.3.post1, torch==2.4.0 and torchvision==0.19.0, though it should run on any current version of the libraries. This is an example of how to create a text completion using the model:

from vllm import LLM, SamplingParams

model_name = "BSC-LT/salamandra-7b-base-gptq"
llm = LLM(model=model_name)

outputs = llm.generate("El mercat del barri ",
                       sampling_params=SamplingParams(
                           temperature=0.5,
                           max_tokens=200)
                       )
print(outputs[0].outputs[0].text)
