Perplexity: Sonar Reasoning

Perplexity's Sonar Reasoning model, built on DeepSeek R1, offers a substantial 127,000 context length and integrates built-in web search, catering to long chain-of-thought applications. However, its overall performance profile indicates significant trade-offs. In terms of speed, Sonar Reasoning tends to exhibit longer response times, ranking in the 17th percentile across benchmarks, placing it among the slower models available. Similarly, its pricing is positioned at premium levels, ranking in the 10th percentile, making it a more expensive option. Analyzing benchmark results, Sonar Reasoning demonstrates notable strengths in specific areas. It excels in Email Classification with 99.0% accuracy (74th percentile) and shows strong capabilities in Reasoning, achieving 88.0% accuracy (86th percentile). General Knowledge is also a strong suit at 97.0% accuracy (55th percentile). Conversely, the model exhibits weaknesses in Ethics, with a 95.0% accuracy (31st percentile), suggesting room for improvement in nuanced ethical considerations. Its Coding performance is moderate at 81.0% accuracy (52nd percentile). Across all benchmarks, the model consistently incurs higher costs and longer durations, reinforcing its premium pricing and slower speed rankings. While its reasoning and classification abilities are commendable, the high cost and extended processing times are significant factors for consideration.
