Microsoft’s star AI chief peers into OpenAI’s code, highlighting an unusual rivalry

… lately, one of DeepMind’s founders, Mustafa Suleyman, has been doing the unthinkable: looking under the hood at OpenAI’s crown jewels — its secret algorithms behind foundation models like GPT-4, people familiar with the matter said.

That’s because Suleyman is now head of AI efforts at Microsoft, which has intellectual property rights to OpenAI’s software as part of its multibillion-dollar investment in the company.

His presence, though, has brought new attention to an unusual dynamic: Microsoft and OpenAI are inextricably linked; they are also competitors.

Don’t let the cute name fool you.

New Attack Technique 'Sleepy Pickle' Targets Machine Learning Models

… The attack method, per Trail of Bits, weaponizes the ubiquitous format used to package and distribute machine learning (ML) models to corrupt the model itself, posing a severe supply chain risk to an organization's downstream customers.

"Sleepy Pickle is a stealthy and novel attack technique that targets the ML model itself rather than the underlying system," security researcher Boyan Milanov said.
