iFlytek Spark X1 - iFlytek's first domestically produced deep reasoning model.

What is Xunfei Xinghuo X1?

iFlytek Spark X1, released by iFlytek on January 15, 2025, is China's first large-scale model with deep thinking and reasoning capabilities trained on a fully domestic computing platform. It more closely resembles human "slow thinking" in problem-solving, achieving industry-leading results with less computing power, and ranking first in several domestic metrics. The newly upgraded Spark X1 shows significant improvements in general tasks such as mathematics, coding, logical reasoning, text generation, language understanding, and knowledge-based question answering, with overall performance comparable to OpenAI o1 and DeepSeek R1. It debuts a unified model for both fast and slow thinking, supporting both modes and simplifying private deployment. The newly upgraded model customization and optimization toolchain supports both SFT and reinforcement learning optimization schemes, with low customization barriers. Spark X1 incorporates more complex data types from various scenarios, improving generalization and further expanding its leading advantage in key industries such as education, healthcare, and the judiciary. The Spark X1 API is also available on the iFlytek Open Platform, offering services to developers and enterprises. In terms of applications, iFlytek Xinghuo X1 has been deployed in multiple real-world scenarios such as education and healthcare, helping to deploy intelligent teacher assistants for high school mathematics in pilot areas and improving the accuracy of AI learning machines in diagnosing and recommending guidance for children's learning.
