PANews reported on February 14 that according to Baidu's official WeChat account, Baidu announced that it will launch the Wenxin Big Model 4.5 series in the next few months and will officially open source it on June 30.

Ironically, Robin Li said last year that open source is actually a form of IQ tax . "When you think rationally about what value a large model can bring and at what cost, you will find that you should always choose a closed source model. Today, closed source models such as ChatGPT and Wenxin Yiyan are definitely more powerful than open source models and have lower inference costs."
