iFlytek Spark V4.0
iFlytek's flagship Spark LLM with end-to-end voice and multimodal interaction.
About
iFlytek Spark V4.0 is the fourth major release of iFlytek's Xinghuo large language model, launched on June 27, 2024 in Beijing and at MWC Shanghai. iFlytek benchmarked it against GPT-4 Turbo on language comprehension, logical reasoning, math, and knowledge question answering, while acknowledging it lagged in coding and multimodal generation.
The release bundled enterprise AI solutions such as the Spark Contract Assistant, intelligent bidding evaluation, and coaching systems, plus consumer features built on end-to-end voice technology including high-noise recognition and multi-dialect switching. Spark V4.0 is available through iFlytek's API platform and SparkDesk product rather than open weights.
