Llama 2 vs. ChatGPT -3, GPT-4 vs. BARD

Amidst the ever-changing realm of artificial intelligence, three powerful language models have emerged: BARD developed by Google, ChatGPT by OpenAI (including GPT-3 and GPT-4), and Llama 2, a brainchild of Meta (formerly Facebook). Each of these models brings its own unique strengths to the table. BARD, with its 137 billion parameters, excels in fast and accurate query processing while supporting both text and image inputs. On the other hand, ChatGPT, with GPT-3’s 175 billion parameters and GPT-4’s massive 100 trillion parameters, showcases impressive conversational AI capabilities, providing users with interactive and natural interactions. Llama 2 stands out for its open-source foundation language models, ranging from 7B to 65B parameters, empowering researchers and developers to access and explore its potential freely. As AI continues to shape the future, the competition and collaboration between these language models drive innovation and offer exciting possibilities for advancing the field of natural language processing.
