Performance Summary
Palmyra X5, Writer's advanced model for enterprise AI agents, demonstrates exceptional reliability with a 98% success rate, consistently providing usable responses. However, its speed ranking places it in the 8th percentile, indicating generally longer response times across benchmarks. In terms of cost, Palmyra X5 exhibits moderate pricing, ranking in the 37th percentile. The model showcases significant strengths in specific areas. It achieves perfect accuracy in both Hallucinations (100.0%) and Ethics (100.0%) benchmarks, notably being the most accurate model at its price point and speed for these categories. Its performance in Mathematics is also a standout, achieving 97.2% accuracy and ranking among the top 3 models. General Knowledge and Reasoning also show solid performance at 99.4% and 80.6% accuracy respectively. Conversely, Palmyra X5 exhibits weaknesses in Email Classification and Instruction Following, with accuracies of 93.8% (24th percentile) and 47.1% (43rd percentile) respectively. While its Coding accuracy is moderate at 83.3%, these areas suggest potential for improvement. The model's extended context length of 1 million tokens, powered by its novel architecture, positions it well for processing large enterprise datasets despite its slower inference speeds.
