At the iFLYTEK Spark Cognitive Model V3.5 upgrade conference on January 30th, iFLYTEK introduced a remarkable new product called "Spark Open Source Model". According to iFLYTEK, the Spark Open Source Model is an improvement on last year's Spark 1.0 version (13B), which not only adds data, capabilities, and toolchains for different application scenarios, but also pays more attention to the requirements of domestic security and controllability in system design. According to the test results released by iFLYTEK, the Spark Open Source-13B outperforms other open source models of the same size by more than 20% in multiple aspects, demonstrating its powerful performance and competitiveness. In addition, the Spark Open Source-13B has undergone deep optimization for domestic software and hardware environments, and has been trained based on the "Feixing No.1" computing platform, achieving full-stack domestic adaptation and optimization. This innovative move by iFLYTEK will further promote the development and application of domestic large-scale models, injecting new vitality into the research and application of artificial intelligence technology.
