Performance Summary
Mistral: Devstral 2 2512 demonstrates moderate speed performance, ranking in the 40th percentile across benchmarks. It offers cost-effective solutions, placing in the 71st percentile for price. A standout feature is its exceptional reliability, achieving a 99% success rate, indicating consistent and usable responses. In terms of specific performance, Devstral 2 excels in acknowledging uncertainty, achieving perfect accuracy in Hallucinations (Baseline) tests, making it the most accurate model at its price point and speed. It shows strong general knowledge with 98.5% accuracy and solid performance in coding (88.0% accuracy) and instruction following (62.0% accuracy). However, its performance in Ethics (Baseline) is comparatively lower at 96.0% accuracy, placing it in the 28th percentile, and it exhibits a significantly longer duration for this benchmark. Overall, Devstral 2's key strengths lie in its specialized agentic coding capabilities, high reliability, and cost-effectiveness, particularly for tasks requiring precise uncertainty acknowledgment. Its primary area for improvement appears to be in the efficiency of ethical reasoning tasks.
