Llama 2 vs GPT-4 vs Claude-2: The Battle of AI Models

3 min


Recent advancements in artificial intelligence (AI) have taken the world by storm, captivating the public’s imagination with the boundless possibilities these technologies offer. One such breakthrough is the development of large language models (LLMs) that have the potential to revolutionize various industries. In this arena, Meta has emerged as a major player, releasing Llama 2, an upgraded version of its successful LLaMa model. This unexpected partnership with Microsoft has further amplified Llama 2‘s impact, as it becomes available on the Microsoft Azure platform catalog and Amazon SageMaker, catering to both research and commercial use through licensing.

The Era of Advanced Language Models:

With the release of Llama 2, Meta has pushed the boundaries of AI capabilities by introducing three pre-trained and fine-tuned parameter models: 7B, 13B, and 70B. These enhancements have resulted in a remarkable 40% increase in pre-trained data, enabling Llama 2 to leverage larger context data for training. Additionally, the model now benefits from GQA (Generalized Question-Answering) to improve inference capabilities significantly.

Competing Models and the Landscape:

In recent months, numerous companies have launched their own LLMs, including TII’s Falcon, Stanford’s Alpaca and Vicuna-13B, and Anthropic’s Claude-2, among others. As these models flood the market, the question arises: how do they compare? In this article, we will delve into a comparative analysis of Llama 2, GPT-4, and Claude-2 to understand their respective strengths, weaknesses, and potential impacts on AI advancements.

The Grades Matter:

Llama 2’s development involved fine-tuning and reinforcement learning with human feedback, encompassing preference data collection and training reward models. The model also introduces novel techniques such as Ghost Attention (GAtt) and is trained on GPT-4 outputs. To evaluate the model’s helpfulness, Meta conducted a comprehensive human study with over 4,000 prompts. The “win rate” metric was utilized to compare Llama 2-Chat models to both open-source and closed-source counterparts like ChatGPT and PaLM, using single and multi-turn prompts.

The Results:

The 70B Llama-2 model performs remarkably well, comparable to GPT-3.5-0301, and outperforms Falcon, MPT, and Vicuna. Llama 2-Chat models prove more helpful for both single and multi-turn prompts, with a win rate of 36% and a tie rate of 31.5% compared to ChatGPT. Additionally, Llama 2-Chat 34B model boasts an overall win rate of over 75% against equivalently sized Vicuna-33B and Falcon 40B models. It even outperforms the PaLM-bison chat model by a significant margin.

Coding Capabilities: The Divide

While Llama 2 excels in various areas, it does lag behind GPT-3.5 and GPT-4 in terms of coding capabilities. With its coding benchmarks falling short, there’s room for improvement. Given that Llama-2 is open-source, there’s an expectation that future iterations will significantly bridge this gap.

Enter Claude-2: The Coding Prodigy

On the other hand, Claude-2 stands out in coding, mathematics, and logical thinking. It showcases exceptional abilities in comprehending PDFs, a task that GPT-4 still struggles with. The model achieved an impressive score of 71.2% on the Codex HumanEval, a specialized evaluation for Python coding skills. However, when it comes to writing, Llama-2 and GPT-4 offer distinctly different experiences. While ChatGPT demonstrates sophisticated word choices, Llama-2 opts for more obvious rhyming word selections.

User Feedback and Impact:

Despite being trained on a smaller scale, Llama-2 has received commendable user feedback from those with beta access. Meta’s approach of using publicly available data and collecting high-quality data has resulted in impressive outputs, comparable to human annotations. However, it is essential to consider the licensing implications for large user bases, as Meta’s permission might be required for continued usage.

Open Source vs. Accessible APIs:

Llama 2, though touted as open-source, comes with certain conditions. This commercially-friendly licensing approach is aimed at supporting the open-source community while safeguarding the model’s integrity. In contrast, models like GPT-4 and Claude 2 are not open-source but can be accessed through APIs.

Microsoft’s Strategic Partnership:

Microsoft’s surprise partnership with Meta comes after a decade-long collaboration with OpenAI. Satya Nadella’s move to explore further avenues in AI has piqued interest in the AI community. Meta’s detailed white paper, in contrast to OpenAI’s perceived lack of transparency, has garnered significant attention. Llama-2 poses a considerable threat to OpenAI’s GPT-4, and its potential to emerge as a leading open-source alternative to GPT-4 has garnered praise from experts.


With the release of Llama-2, Meta has introduced a potent AI model with distinct capabilities and strengths, especially in the domain of language generation. While it may currently lag behind GPT-4 in coding abilities, its open-source nature promises continuous improvement. Claude-2, on the other hand, shines in coding and logical thinking, making it a formidable contender. Microsoft’s strategic partnership with Meta further adds to the dynamic AI landscape, offering exciting possibilities for researchers, developers, and businesses alike. As the battle of AI titans continues, the future holds immense potential for further advancements in the AI realm.
