@yogthos it would seem that it’s rather “open” to download the source code and access some data after signing in as a scientist. Far from fully open-source for an AI tool, by most of the definitions.
scientists can now download the software code and use the artificial intelligence (AI) tool for non-commercial applications
(emphasis mine)
Which means that this is an open core code, not open source proper due to the non-commercial restriction, unfortunately.
Also, just a sidenote, while AlphaFold2 training data is available for download (unsure if AlphaFold3 will follow suit), the OSI recently released its definition for open source AI models, and there is no requirement that the training data needs to also be open for a model to be considered “open source”, which is extremely disappointing and will degrade the meaning of open source.
