Baidu: ERNIE 4.5 21B A3B

Baidu's ERNIE 4.5 21B A3B, a sophisticated Mixture-of-Experts model with 21B total parameters and 3B activated per token, demonstrates a balanced performance profile. It offers competitive response times, ranking in the 58th percentile for speed, and consistently provides among the most competitive pricing, placing in the 82nd percentile. Notably, its reliability is exceptional, boasting a 98% success rate across benchmarks, indicating minimal technical failures. The model exhibits strengths in cost-efficiency across various tasks, consistently ranking in the top 20% for cost-effectiveness on most benchmarks. Its accuracy in "Hallucinations (Baseline)" is 92.0%, suggesting a good ability to acknowledge uncertainty. However, its accuracy in core cognitive areas like "General Knowledge" (94.3%), "Ethics" (94.5%), "Mathematics" (82.0%), "Email Classification" (93.5%), "Instruction Following" (51.2%), "Reasoning" (50.0%), and "Coding" (77.2%) generally falls in the lower percentiles (23rd-45th), indicating room for improvement in these specific domains compared to other models. Its extensive 120,000 context length and advanced post-training techniques are key features, but the benchmark results suggest that while it is highly reliable and cost-effective, its raw accuracy in complex reasoning and knowledge-based tasks is not its primary strength.
