1. Understanding the Key Differences: Llama 3 70B vs. GPT-4
When comparing Llama 3 70B and GPT-4, it’s important to look at several key aspects. These include their basic specifications, cost implications, and overall performance in various tasks. By understanding these elements, you can better determine which model suits your specific needs. Let’s break down the basics.
1.1 Basic Comparison of Llama 3 70B and GPT-4
Llama 3 70B and GPT-4 differ in several fundamental ways. One key difference is the context window size. Llama 3 70B has an 8K context window length. GPT-4 offers a much larger 128K context window. However, because Llama 3 is open-source, developers have created models extending its context window up to 1 million tokens. GPT-4’s knowledge base is updated until April 2023, while Llama 3’s extends to December 2023. GPT-4 supports function calling, a feature currently unavailable in Llama 3. Also, Llama 3 doesn’t currently handle images. Meta has indicated that longer context lengths and more capabilities are coming soon.
1.2 Cost Comparison: Is Llama 3 70B More Affordable Than GPT-4?
Cost is a significant factor when choosing between Llama 3 70B and GPT-4. Llama 3-70B’s open-source nature provides multiple deployment options. You can run it locally, paying only for hardware and electricity, or use a hosted version from various providers. GPT-4 is generally more expensive. GPT-4 costs $30 per million input tokens and $60 per million output tokens. Using Llama 3-70B with Azure, the most expensive provider, is still cheaper than GPT-4. It’s about 8 times cheaper for input tokens and 5 times cheaper for output tokens (USD/1M Tokens). Groq, the cheapest provider, offers even greater savings. It’s more than 50 times cheaper for input tokens and 76 times cheaper for output tokens (USD/1M Tokens).

1.3 Performance Comparison: Latency and Throughput
When evaluating the performance of Llama 3 70B and GPT-4, latency and throughput are critical metrics. In terms of latency, selecting any of the top five providers on the graph will result in faster response times with Llama 3 70B compared to GPT-4. Given that GPT-4’s latest recorded latency is 0.54 seconds to the first token, Llama 3 70B is a better option for low-latency applications. Regarding throughput, Llama 3, when hosted on the Groq platform, achieves the fastest rate, generating 309 tokens per second. This is approximately 9 times faster than GPT-4, which generates 36 tokens per second. Fireworks and Together are also good alternatives.

3.2 Document Summarization: Assessing Concise and Coherent Summaries
Both Llama 3 70B and GPT-4 excel at document summarization, making this a generally easy task for both models. When tasked with summarizing a technical report, both models captured key data and concluded coherently. Llama 3 70B provided a concise summary, while GPT-4 offered a slightly longer output. Both summaries captured all three aspects really well. Here’s what Llama 3 generated:
The document compares the performance of four language models (Gemini Pro, GPT-4 Turbo, GPT-3.5 Turbo, and Claude 2.1) in classifying customer support tickets as resolved or not. The experiment used 200 test cases and evaluated the models based on accuracy, recall, precision, and F1 score. The results showed that Gemini Pro outperformed the other models, with an accuracy of 74% and an F1 score of 76.69%. Claude 2.1 had a high recall rate, while GPT-4 Turbo had a high precision rate. The experiment highlights the importance of prompt engineering and the need to consider the specific requirements of the task when choosing a model.And here’s the slightly longer output by GPT-4:
The document details an experiment conducted to compare the performance of four models - GPT-3.5 Turbo, GPT-4 Turbo, Claude 2.1, and Gemini Pro - in classifying customer support tickets as resolved or unresolved. The experiment was inspired by a customer, Pylon, who wanted to improve the accuracy of their existing classifier. The results showed that Gemini Pro was the best performing model, with an accuracy of 74% and an F1 score of 76.69%. Claude 2.1 had a high recall rate, while GPT-4 Turbo showed high precision. The document also discusses the challenges of the task, such as language variability and edge cases, and the importance of customizing prompts and avoiding overfitting. The authors suggest that the findings could be useful for all users of Language Learning Models (LLMs) and plan to further investigate the performance of the models and the potential benefits of fine-tuning a model using Pylon's classifier data.3.3 Reasoning Abilities: Verbal and Arithmetic Reasoning
Evaluating the reasoning abilities of Llama 3 70B and GPT-4 reveals insights into their cognitive strengths. Both models performed poorly on verbal reasoning questions. However, they showed similar performance on arithmetic reasoning questions, with GPT-4 having just one more correct answer than Llama 3 70B. This indicates that while both models struggle with verbal reasoning, they are relatively capable in arithmetic reasoning tasks.
