Recently, iFlytek officially released its latest deep reasoning large model - Xunfei Spark X1.5. This model, based on fully domestic computing power, has made significant technological advancements. It not only adopts an advanced MoE (Mixture of Experts) architecture, but also has a total parameter count of up to 29.3 billion, with 3 billion active parameters. This means that the processing capability of Spark X1.5 is very powerful, and it can be easily deployed on a single Ascend standard server. The reasoning efficiency is 100% higher than the previous generation X1, and its end-to-end performance has reached over 93% of international industry products.
In terms of core capabilities, Spark X1.5 covers six areas: language understanding, text generation, knowledge Q&A, logical reasoning, mathematics, and code processing, fully matching international mainstream large models. Among them, its mathematical ability is particularly outstanding. According to the Gaokao math test, Spark X1.5 scored as high as 145 points, exceeding GPT-5's 141 points and DeepSeek V3.2-Exp's 140 points. In the International Mathematical Olympiad, Spark X1.5 also demonstrated its strong capabilities, successfully solving Problem 3 of the 2025 competition.
Additionally, Spark X1.5 shows great potential in education and healthcare fields. In tasks such as assisting teaching, learning, and medical knowledge Q&A, it outperforms GPT-5 and DeepSeek V3.2-Exp, with the average score of the education model breaking through the high threshold of 85 points. At the same time, the model's multilingual capabilities have been significantly improved, now supporting more than 130 languages, with overall performance reaching over 95% of ChatGPT-5, especially showing excellent results in 14 key languages such as Latin America and ASEAN.
Moreover, the Spark Speech Simultaneous Interpretation Large Model 2.0 ranked first in eight core dimensions in the latest "China AI Translation Technology Evaluation," highlighting iFlytek's leading position in AI translation technology.
iFlytek's recent release undoubtedly brings new changes to the field of deep reasoning. The powerful capabilities of Spark X1.5 can not only meet extensive application needs, but also provide strong support for innovation in multiple industries such as education and healthcare.
