Baidu just open-sourced its ERNIE 4.5 model collection on Hugging Face, spanning lightweight text models to massive multimodal models reaching 424B parameters. The release provides checkpoints in both PyTorch and PaddlePaddle alongside dedicated Thinking variants, giving open-source developers a serious heavyweight alternative.
ERNIE 4.5 just swept GPT-4.5 in a three-game chess showdown, winning all three matches decisively. The model demonstrated tighter instruction-following and sharper positional decision-making, even sealing the final match with a 10-move checkmate. It is a reminder that frontier logic tests do not always belong exclusively to OpenAI.
Baidu just announced plans to open-source its upcoming Ernie 4.5 large language model series on June 30. The models will roll out to users over the coming months before the code is released. The shift comes shortly after DeepSeek-R1 shook up the industry, putting pressure on tech giants to rethink their open-source AI strategies.
