Last month, Microsoft confirmed a major investment in OpenAI, the company behind ChatGPT. This comes on top of a $1 billion investment in OpenAI in 2019. As part of that deal, OpenAI agreed to build its AI models on Microsoft Azure.
Then last month, Microsoft also announced the general availability of its Azure OpenAI Service, allowing more businesses to use OpenAI's Azure-hosted and trained large language models (LLMs), such as GPT-3.5 -- the LLM behind ChatGPT. Meanwhile, Microsoft's Power BI is using GPT-3 to generate formulae and expressions.
