Efficiency comparability between these fashions for accuracy and response time in a RAG question-answering setup.
With the introduction of the open-source language mannequin Mistral 7B by a French startup, Mistral, the breathtaking efficiency demonstrated by proprietary fashions like ChatGPT and claude.ai grew to become obtainable for the open-source group as nicely. To discover the feasibility of utilizing this mannequin on resource-constrained programs, its quantized variations have been proven to keep up nice efficiency.
Regardless that 2-bit quantized Mistral 7B mannequin handed accuracy check with flying colours in our earlier examine, it was taking round 2 minutes on common to reply to questions on a Mac. Enter TinyLlama [1], a compact 1.1B language mannequin pretrained on 3 trillion tokens with the identical structure and tokenizer as Llama 2. It’s aimed for extra resource-constrained environments.
On this article, we’ll examine the accuracy and response time efficiency of query answering capabilities of quantized Mistral 7B towards quantized TinyLlama 1.1B in an ensemble Retrieval-Augmented Technology (RAG) setup.

This check shall be performed on a MacBook Air M1 with 8GB RAM. Because of its restricted compute and reminiscence sources, we’re adopting quantized variations of those LLMs. In essence, quantization includes representing the mannequin’s parameters utilizing fewer bits, which successfully compresses the mannequin. This compression leads to lowered reminiscence utilization, quicker execution occasions, and elevated vitality effectivity however on the compromise of accuracy. We shall be utilizing the 2-bit quantized Mistral 7B Instruct and 5-bit quantized TinyLlama 1.1B Chat fashions within the GGUF format for this examine. GGUF is a binary format that’s designed for quick loading and saving of fashions. To load such a GGUF mannequin, we shall be utilizing the llama-cpp-python library, which is a…
