xAI: Grok 4.5

Grok 4.5, xAI's latest model, demonstrates frontier performance in key areas, particularly excelling in knowledge work and STEM. While its speed performance is moderate, ranking in the 31st percentile across benchmarks, its pricing tends to be premium, positioned in the 6th percentile. A standout feature is its exceptional reliability, achieving a perfect 100% success rate across all evaluated benchmarks, indicating consistent and usable responses without technical failures. In terms of specific benchmark results, Grok 4.5 achieved 96.0% accuracy in Coding (Baseline), placing it in the 94th percentile, though at a higher cost and moderate duration. Its Reasoning (Baseline) performance is particularly impressive, reaching 100.0% accuracy. This makes it the most accurate model at its price point and among models of comparable speed, highlighting a significant strength in complex problem-solving. For Mathematics (Baseline), it scored 93.0% accuracy, placing it in the 62nd percentile, again at a premium cost. Overall, Grok 4.5's key strengths lie in its high accuracy across coding and reasoning tasks, with perfect scores in the latter, and its unparalleled reliability. Its primary weakness is its premium pricing, which may limit accessibility for some users, and its moderate speed.
