This is the current position with the DCO anyway. If the contributor has copy and pasted (and maybe adapted) from Stack Overflow they are still realistically the only person that can make that judgement. > Our current AI policy was built on the assertion that it's impossible to > sign the DCO for AI output, and I think that's still right.

It's certainly possible for LLMs to replicate copyright material but by far the biggest influence is the code *in the project* that shapes the output. It is basically pattern matching and predicting after all. What level of reassurance the submitter needs to be able to certify with their DCO is up to them. We can't police it, like every other submission we rely in the submitters good faith representation of what they have done. > If we decide that we don't care as much about the legal risks any more > and that we're willing to accept them to some extent, that should be > explicitly reflected in the policy. > > It seems to me that the cleanest way to do it is to exempt correctly > advertised (with 'AI-used-for:') AI output from the DCO requirement and > instead add to the 'AI-used-for:' definition some relaxed version of it, > e.g. "I have reviewed the contribution for potential licensing issues > and haven't found a reason to doubt that I have the rights to submit > this AI generated content under the open source license indicated in the > file".

I don't think we are asking them to work in a legally grey area, we are insisting they are confident there is no legal risk in what they submit. -- Alex Bennée Virtualisation Tech Lead @ Linaro
