China Telecom has released the trillion-parameter large model, Starry Semantics, which can reduce design costs by 95%. Starry Semantics is a self-developed large model by China Telecom, and its upgrade has led to significant improvements in four areas: hallucination suppression, extrapolation window, interactive experience, and multi-turn understanding. China Telecom has also launched more than ten industry large models covering fields such as education, healthcare, and tourism. Among them is the Starry Education large model, which can assess, comment on, and suggest improvements for a Chinese-English essay in just 15 seconds. Additionally, China Telecom plans to open source hundred-billion-parameter and trillion-parameter large models in the future.
