Microsoft and OpenAI are collaborating on a $100 billion 'Stargate' AI supercomputer project, aiming to launch by 2028.

The 'Stargate' project represents the culmination of their joint supercomputer initiatives and is poised to be the largest in the U.S.

Projected expenses for the AI supercomputer could surpass $115 billion, primarily due to the acquisition of specialized AI chips.

The partnership is evaluating alternatives to Nvidia's technology and investigating diverse energy sources for the project.

The announcement includes the development of Custom GPTs for ChatGPT, an image that disrupts ChatGPT's functionality, and a comparison with Google's Gemini to OpenAI's GPT-4.

The project highlights the expanding alliance between Microsoft and OpenAI, and the substantial investments being made in AI's infrastructural future.
