Microsoft on the investment of a cool $1B in OpenAI:
The companies will focus on building a computational platform in Azure of unprecedented scale, which will train and run increasingly advanced AI models, include hardware technologies that build on Microsoft’s supercomputing technology, and adhere to the two companies’ shared principles on ethics and trust. This will create the foundation for advancements in AI to be implemented in a safe, secure and trustworthy way and is a critical reason the companies chose to partner together.
Don't let the name OpenAI fool you, as there is no word from either company on whether their efforts will be open sourced.
However, OpenAI does publish a charter to which they say they hold.
Either way, it seems to align with Satya's Microsoft that believes in empowering people to do their work and in doing it ethically and morally.
