The Spark X1.5 big model was fully trained on domestic computing platforms, significantly improving training efficiency, especially in multilingual processing capabilities reaching 130 languages, further promoting intelligent upgrades in fields such as education and healthcare. Liu Qingfeng pointed out that the realization of benefits in the AI industry depends on four core elements: independent control, integrated software and hardware, industry depth, and personalization.

The model adopts a MoE architecture, with a total of 293B parameters and 30B activated parameters. It can be deployed on a single Ascend standard server, with a 100% improvement in inference efficiency compared to X1, and end-to-end performance exceeding 93% of international competitors. Its six core capabilities match international mainstream large models, with international leading mathematical capabilities, scoring higher than GPT-5 in Gaokao mathematics evaluation, providing correct answers to International Mathematical Olympiad problems, and performing better than GPT-5 in tasks related to educational and medical large models.

In terms of technical highlights, iFLYTEK has overcome the efficiency of long thinking chain reinforcement learning training, with deep reasoning training efficiency increased to over 84%, and has also launched the world's first non-autoregressive speech large model architecture, greatly improving inference efficiency. The 15.0 version of iFLYTEK Input Method has successfully applied this new technology, providing users with a smoother experience when typing text.

In addition, iFLYTEK has also released integrated software and hardware solutions, such as AI + microphone array and AI + speaker array, allowing AI technology to better adapt to various application scenarios. The X5 smart office book uses a high-performance microphone array, which can clearly identify voice even in noisy environments. iFLYTEK's translation earphones achieve an accuracy rate of up to 97.1%, maintaining good recognition effects even in noisy environments.

Liu Qingfeng stated that iFLYTEK is committed to providing technological support for China's national strategy in the era of hard science and technology, promoting industry development and offering users a more convenient AI experience.
