Meta: Llama 3.1 8B Instruct

Meta's Llama 3.1 8B Instruct model, released on July 22, 2024, demonstrates a balanced performance profile, particularly excelling in cost-efficiency. It consistently offers among the most competitive pricing, ranking in the 98th percentile across six benchmarks. The model exhibits competitive response times, placing in the 56th percentile for speed. Reliability is strong, with an 89% success rate, indicating consistent provision of evaluable responses. In terms of specific benchmarks, Llama 3.1 8B Instruct shows notable strengths in Classification and Ethics, achieving 95.0% accuracy in Email Classification and 98.5% in Ethics, with both categories also being highly cost-effective. It is highlighted as the most accurate model at its price point for these tasks. However, the model shows weaknesses in more complex cognitive tasks such as Instruction Following (32.2% accuracy), Reasoning (46.0% accuracy), and General Knowledge (87.5% accuracy), where its accuracy percentiles are lower. While its Coding performance is moderate at 69.0% accuracy, its reasoning duration is notably slower than average. Overall, this model is a strong contender for cost-sensitive applications requiring high reliability and strong performance in classification and ethical reasoning.
