Recently, Baidu's Ernie Bot launched a "Professional Edition Invitational Test" event. Users can apply for the experience by clicking on the Ernie Bot official website to enter the event page. The application starts daily at 9 AM during the event period. This event runs from October 28, 2023, to October 31, 2023. If successfully granted an invitational test slot, users can immediately experience the more powerful Ernie Large Model 4.0 from that day. Upon obtaining the test qualification, users can select either the Ernie Large Model 3.5 or Ernie Large Model 4.0 for conversations when clicking on a new dialogue. According to Baidu's official introduction, Ernie 4.0 has significantly enhanced capabilities in understanding, generating, logic, and memory. The improvements in understanding and generating capabilities are similar, while the enhancements in logic and memory are even greater; the improvement in logic is nearly three times that of understanding, and the enhancement in memory is more than twice that of understanding. The event lasts for 30 days, allowing participants to experience the more powerful Ernie Large Model 4.0 in their dialogues.
