ByteDance Seed: Seed-2.0-Mini

ByteDance Seed: Seed-2.0-Mini, released on February 26, 2026, is designed for latency-sensitive, high-concurrency, and cost-sensitive applications, offering performance comparable to Seed-1.6 with a substantial 256k context length and four reasoning effort modes. While it aims for fast response, its speed ranking indicates it tends to have longer response times, placing it in the 12th percentile across benchmarks. Conversely, it offers competitive pricing, ranking in the 43rd percentile. A significant strength is its exceptional reliability, boasting a 99% success rate, indicating consistent and usable responses. In terms of benchmark performance, Seed-2.0-Mini demonstrates strong capabilities in classification and reasoning tasks, achieving 99.0% accuracy in Email Classification and 96.0% in Reasoning. However, a notable weakness is its performance in the Hallucinations benchmark, where it scored only 56.0% accuracy, suggesting a tendency to generate information rather than acknowledge uncertainty. Its Ethics performance is moderate at 97.0% accuracy. The model's duration metrics across benchmarks are generally high, reinforcing its lower speed ranking, particularly in the Hallucinations and Reasoning tests. Overall, Seed-2.0-Mini excels in reliability and specific task accuracies, making it suitable for applications where consistent output and strong classification/reasoning are paramount, provided latency can be managed.
