OpenAI blasts DeepSeek for “inappropriately” copying ChatGPT—but is it a case of innovation or infringement? My colleague Lea Frermann and I provide a lay-summary on DeepSeek’s new R1 model, its resourceful approach, and the AI-battles unfolding. Read more: theconversation.com/openai-says-...

OpenAI says DeepSeek ‘inappropriately’ copied ChatGPT – but it’s facing copyright claims too
The upside to this war of words? More competition is boosting consumer choice, including with OpenAI’s release over the weekend of a new AI model, o3-mini.

Starting with Shaanan Cohney (@shaananc.bsky.social), from the University of Melbourne, on the first topic, defining appropriate technical privacy notions for practice!

Utility in what sense? It does improve reasoning capabilities (both formally and informally). And not just restricted to ChatGPT! There are a large number of models that are reasoning trained (or based) now. I’m not sure I follow your key issue? Semantic meaning in context is the main training?

Some of your statements about their training are no longer true. The current generation of foundation models (o3 etc) are explicitly trained on reasoning data. Further, formal reasoning data (using special purpose languages) is increasingly integrated.

I was on NPR with @bobbyallyn.bsky.social re Australia’s teen social media ban. Tests by the US National Institute of Standards and Technology found that age algorithms are off by an average of 5yrs for West Africans–discriminating in practice. 🎧 Take a listen! www.npr.org/2024/12/09/n...

How will Australia's teen social media actually work?
Australia's Parliament has passed one of the strictest social media crackdowns in the world. Under the new law, anyone under 16 years old will be banned from opening a social media account.

Social media platforms will face financial penalties starting in the 10s of millions if they don’t implement technical measures to block under 16s from social media!

This was a terrible review.

Parliamentary Hearing for the Australian social media ban lasts only three hours—two days after 77 submissions were filed (and presumably not read). This is making a mockery of the legislative process! Sources say MPs are getting cold feet but told to hold the party line. #auspol

The Australian Government is cramming through its under-16yrs old social media ban with an insane 24 hour period for public notice and comment!!! 🤯 Kudos to my team at unimelb for putting a submission together so fast.

Only if you look closely on the slide, the formal specification has a bug!
