近日，人工智能大模型价格竞争日益激烈，多家美国人工智能公司下调大模型使用价格。

美国开放人工智能研究中心OpenAI21日表示，当天起将把面向开发者端的前沿人工智能大模型——GPT-5.6 Sol模型基准价格下调逾20%，调整后的优惠价格三个月有效。    (ECNS) -- A humanoid robot named Tiangong robot Omni clocked 45.66 seconds to win the gold medal at the 400-meter contest during the 2nd World Humanoid Robot Games in Beijing on Sunday.    The robot's performance was notable not only for its speed but also for its unusual running style. Leaning sharply forward, it swung both arms close to its face, creating a comical pose that looked as if it were covering its face while sprinting.        The quirky gait quickly went viral online, with Chinese netizens jokingly dubbing it a "socially anxious sprint". The contrast between the robot's high-speed performance and its almost bashful posture has made it an unexpected internet sensation.    The movement was not manually programmed by engineers to imitate humans. Instead, the distinctive gait emerged autonomously through reinforcement learning in a simulation environment.    During training, the robot learned that twisting its waist and driving its movement through the hips required less effort than rapidly swinging its arms. The strategy also helped reduce heat buildup in the shoulder joints. At the same time, leaning forward shifted its center of gravity in a way that improved balance and helped increase running speed.    With a time of 45.66 seconds, Omni's performance is already approaching the level of elite male human athletes in China.    (By Gong Weiwei)                            。上月底，OpenAI还下调了旗下其他模型的价格。其中，中端模型的价格下调20%，低成本模型的价格下调80%。此外，字母表公司旗下的谷歌日前发布了Gemini 3.7 Flash，并同步下调定价，价格约为上一版本的一半。有美媒分析认为，人工智能大模型价格竞争日益激烈，来自中国的部分人工智能公司的大模型的开源和定价策略给美国的公司带来了压力。
