Chinese startup DeepSeek will make its models' code publicly available, it said on Friday, doubling down on its commitment to open-source artificial intelligence.

DeepSeek's initial model release already included so-called "open weights" access to the underlying data representing the strength of the connections between the model's billions of simulated neurons. That kind of release allows end users to easily fine-tune those model parameters with additional training data for more targeted purposes.

Chinese AI sensation DeepSeek plans to release key codes and data to the public starting next week, an unusual step to share more of its core technology than rivals such as OpenAI have done.
