iFlytek announced a significant upgrade to its deep reasoning large model, iFlytek Spark X1. As the industry's only deep reasoning large model trained on entirely domestically produced computing power, iFlytek Spark X1 has achieved remarkable breakthroughs in several key areas, further solidifying its leading position in the AI field.
This upgrade significantly improves iFlytek Spark X1's performance across various general tasks, including mathematics, coding, logical reasoning, text generation, natural language understanding, and knowledge question answering. Despite having an order of magnitude fewer parameters than comparable models, its overall performance rivals OpenAI o1 and DeepSeek R1, demonstrating that domestically-trained, fully self-developed large models have the capability and potential for continuous innovation to reach the highest industry standards.
The upgraded iFlytek Spark X1 incorporates more complex data from various scenarios, resulting in significant improvements in generalization capabilities. It showcases industry-leading performance across multiple industry tasks, particularly expanding its lead in key sectors such as education, healthcare, and the judiciary. For example, in the judicial sector, the upgraded Spark X1 can summarize case facts and judgment reasons, analyze points of contention, quickly locate key information in materials, and accurately output content.
Furthermore, iFlytek Spark X1 is the first to launch a unified model for fast and slow thinking, enabling a single model to support both thinking modes with simplified private deployment. The newly upgraded model customization and optimization toolkit supports both SFT and reinforcement learning optimization schemes, lowering the customization threshold and further reducing the barrier to entry for businesses using AI.
Three major technological innovations underpin this upgrade: a large-scale multi-stage reinforcement learning training method, a unified training method based on fast and slow thinking, and engineering and technological system innovations ensuring efficient and stable training based on domestic computing power. These technological innovations provide a solid foundation for the comprehensive upgrade of Spark X1.
The iFlytek Spark X1 API is now available on the iFlytek Open Platform, providing services to developers and businesses. Currently, fine-tuning services are available on the iFlytek Xingchen MaaS platform. Developers and businesses can visit https://xinghuo.xfyun.cn/sparkapi to experience the powerful functions of the Spark X1 API.
iFlytek stated that this upgrade not only enhances the performance of iFlytek Spark X1 but also provides dual support for enterprise AI implementation, lowering the barrier to entry and promoting the application of AI technology in more industries.
