Introduction
On July twenty third, 2024, Meta launched its newest flagship mannequin, Llama 3.1 405B, together with smaller variants: Llama 3.1 70B and Llama 3.1 8B. This launch got here simply three months after the introduction of Llama 3. Whereas Llama 3.1 405B outperforms GPT-4 and Claude 3 Opus in most benchmarks, making it probably the most highly effective open-source mannequin out there, it will not be the optimum alternative for a lot of real-world functions attributable to its sluggish era time and excessive Time to First Token (TTFT).
For builders seeking to combine these fashions into manufacturing or self-host them, Llama 3.1 70B emerges as a extra sensible different. However how does it evaluate to its predecessor, Llama 3 70B? Is it value upgrading in the event you’re already utilizing Llama 3 70B in manufacturing?
On this weblog submit, we’ll conduct an in depth comparability between Llama 3.1 70B and Llama 3 70B, inspecting their efficiency, effectivity, and suitability for numerous use circumstances. Our objective is that will help you make an knowledgeable choice about which mannequin most closely fits your wants.

Overview
- Llama 3.1 70B: Finest for duties requiring in depth context, long-form content material era, and complicated doc evaluation.
- Llama 3 70B: Excels in velocity, making it ideally suited for real-time interactions and fast response functions.
- Benchmark Efficiency: Llama 3.1 70B outperforms Llama 3 70B in most benchmarks, significantly in mathematical reasoning.
- Pace Commerce-Off: Llama 3 70B is considerably sooner, with decrease latency and faster token era.
Llama 3 70B vs Llama 3.1 70B
Primary Comparability
Right here’s a fundamental comparability between the 2 fashions.
| Â | Llama 3.1 70B | Llama 3 70B |
| Parameters | 70 billion | 70 billion |
| Value-Enter tokens-Output tokens | $0.9 / 1M tokens$0.9 / 1M tokens | $0.9 / 1M tokens$0.9 / 1M tokens |
| Context window | 128K | 8K |
| Max output tokens | 4096 | 2048 |
| Supported inputs | Textual content | Textual content |
| Operate calling | Sure | Sure |
| Data cutoff date | December 2023 | December 2023 |
These important enhancements in context window and output capability give Llama 3.1 70B a considerable edge in dealing with longer and extra complicated duties, regardless of each fashions sharing the identical parameter rely, pricing, and information cutoff date. The expanded capabilities make Llama 3.1 70B extra versatile and highly effective for a variety of functions.
