"Large Language Models (LLMs) are one of the hottest topics in artificial intelligence (AI) research and interest in them and how they can be used in generative AI applications has spilled into the mainstream media." "The sudden popularity of LLMs arises because of their demonstrated usefulness in supporting a wide range of applications and tasks including text summarisation, text-to-image and text-to-video generation, conversational search, machine translation as well as their role in many Generative AI (GenAI) applications." "The cost for researchers to build an open sourced LLM had required substantially large funding, as the creation of LLMs demanded extensive data and GPU resources, which could cost anywhere from €1 to €100 million." "Meta's LLaMA-2 has imposed certain usage conditions through its acceptable use policy." "BLIP-2 comprises of two pre-training stages. The first stage uses frozen image encoders to learn visual-text representations while the second stage uses a frozen language model to generate vision-to-language understanding." "MiniGPT4 demonstrated successful responses to 65% of requests, compared to BLIP-2 with less than 10% success. Additionally, both models were evaluated on image captioning using the MS-COCO caption benchmark, with BLIP-2 achieving under 30% success and MiniGPT4 achieving over 65%."
