Llama 3.3: Meta’s Efficient and Powerful LLM

In contrast, Llama 3.3, which was developed by Meta, is a 70B parameter model specifically designed for text-based tasks. The architecture and training methodology set it apart in several ways:

• Optimized transformer architecture
• Trained using supervised fine-tuning (SFT) and reinforcement learning with human feedback (RLHF)
• Incorporates 15 trillion tokens of publicly available data in its training
• The proposed method employs grouped query attention (GQA) for improved inference scalability
• Supports eight core languages with a focus on quality over quantity

Performance Comparison

Now that we’ve established the basic characteristics of each model, let’s delve into their performance across various benchmarks. This comparison will help illustrate their strengths in different areas.

Benchmark	Meaning	Qwen 2.5 (72B)	Llama 3.3 (70B)
MMLU	MMLU (Massive Multitask Language Understanding) evaluates general language understanding across diverse tasks.	86.8	86.0
HumanEval	HumanEval tests a model’s ability to write correct Python code based on given problem descriptions.	59.1	88.4
MATH	MATH assesses mathematical problem-solving capabilities of models.	83.1	77.0
MBPP	MBPP (Modern Biology Problem Solving) measures AI’s ability to solve problems in biological sciences.	88.2	87.6

As we can see from this table, Llama 3.3 70b demonstrates particular strengths in coding tasks (HumanEval, MBPP) and instruction following (IFEval). In contrast, Qwen 2.5 72b demonstrated balanced performance across various domains, excelling in MMLU and MATH. If you would like to know more about the llama3.3 benchmark knowledge.
