$$OpenAI achieved a financial milestone in the full year of $2023,$ surpassing the one$-$billion$-$dollar mark for the first time and reaching $$1\mathrm{.}6$ billion in revenue. This figure represents a year$-$over$-$year $($YoY$)$ increase of $800\%,$ or eight times, soaring from the $$200$ million recorded in $2022.$ In $2021,$ the company seemingly reported revenues amounting to $$34$ million. Since the commencement of revenue recording, $2020$ is believed to have marked the lowest figure at $$3\mathrm{.}48$ million. Reportedly, OpenAI$$s initial recorded revenue was in $2016$ at $$13\mathrm{.}81$ million. OpenAI$$s substantial increase in revenue is closely tied to the success of the company$$s product, ChatGPT, in the generative AI landscape$.$

In light of this statement, discuss the important role of diversified revenue streams in OpenAI's financial strategy and evaluate how licensing agreements, commercial partnerships, and API $($Application Programming Interface$)$ offerings can contribute to the organization's financial sustainability and growth.
