Introduction
On July 23, 2024, Meta launched its latest flagship model, the Llama 3.1 405B, along with smaller variants: the Llama 3.1 70B and Llama 3.1 8B. This launch came just three months after the unveiling of the Llama 3. While the Llama 3.1 405B outperforms GPT-4 and Claude 3 Opus in most benchmarks, making it the most powerful open source model available, it may not be the optimal choice for many real-world applications due to its slow generation time and high time-to-first-token (TTFT).
For developers looking to integrate these models into production or host them themselves, Llama 3.1 70B emerges as a more practical alternative. But how does it compare to its predecessor, Llama 3 70B? Is it worth upgrading if you’re already using Llama 3 70B in production?
In this blog post, we will conduct a detailed comparison between the Llama 3.1 70B and the Llama 3 70B, examining their performance, efficiency, and suitability for various use cases. Our goal is to help you make an informed decision on which model best suits your needs.

Overview
- Call 3.1 70B:Ideal for tasks that require extensive context, extensive content generation, and complex document analysis.
- Call 3 70B:It excels in speed, making it ideal for real-time interactions and quick response applications.
- Benchmark performance:Llama 3.1 70B outperforms Llama 3 70B on most tests, particularly in mathematical reasoning.
- Speed compensation:Llama 3 70B is significantly faster, with lower latency and faster token generation.
Llama 3 70B vs Llama 3.1 70B
Basic comparison
Here is a basic comparison between the two models.
| Call 3.1 70B | Call 3 70B | |
| Parameters | 70 billion | 70 billion |
| Price-Input Tokens-Output Tokens | $0.9/1 million tokens$0.9/1 million tokens | $0.9/1 million tokens$0.9/1 million tokens |
| Context window | 128K | 8K |
| Maximum number of output tokens | 4096 | 2048 |
| Accepted entries | Text | Text |
| Function call | Yeah | Yeah |
| Deadline for knowledge | December 2023 | December 2023 |
These significant improvements in context window and output capability give the Llama 3.1 70B a substantial advantage in handling longer and more complex tasks, even though both models share the same parameter count, price, and knowledge deadline. The expanded capabilities make the Llama 3.1 70B more versatile and powerful for a wider range of applications.
