In our evaluation, we scrutinized ChatGPT, Bard, and Llama 2 across a range of capabilities, including creativity, coding skills, mathematical proficiency, and commonsense reasoning.

1. Creativity

For a test of creativity and humor, we subjected Llama 2 to a unique creativity and sarcasm assessment. We tasked it with simulating a conversation between two individuals debating the merits of space travel. In this domain, ChatGPT outperformed the rest, with Llama 2 closely trailing behind, surpassing Google’s Bard. While ChatGPT retains its crown as the creativity champion, Llama 2 shows promise, hinting at its creative potential.

2. Coding Skills

When it comes to coding prowess, Llama 2 demonstrated considerable potential. We challenged ChatGPT, Bard, and Llama 2 to create a functional to-do list application, construct a simple Tetris game, and design a secure website authentication system. ChatGPT excelled in all three tasks, while Bard and Llama 2 performed similarly, providing functional code for the to-do list and authentication system but struggling with the Tetris game. Llama 2’s capability is exemplified in its creation of a to-do app.

3. Math Skills

In the realm of mathematics, Llama 2 showed promise compared to Bard but lagged behind ChatGPT in solving algebra and logic problems. Interestingly, Llama 2 managed to tackle math problems that both ChatGPT and Bard had faltered with in their earlier iterations. While it may trail ChatGPT in math, Llama 2 demonstrates considerable potential.

4. Common Sense and Logical Reasoning

Common sense reasoning remains a challenge for many chatbots, including ChatGPT. Our assessment tasked ChatGPT, Bard, and Llama 2 with solving a series of common sense and logical reasoning problems. Once again, ChatGPT outshone its counterparts, with Bard holding a slight edge over Llama 2.

While Llama 2 may not have reached the pinnacle of AI language models, it should be noted that it is relatively new, primarily classified as a “foundational model” rather than a “fine-tuned” model. Foundational models are designed with adaptability in mind, catering to a broad spectrum of tasks, albeit with some limitations.

On the other hand, fine-tuned models are specifically tailored to excel in particular domains, similar to ChatGPT’s specialization in chat applications.
