History

Historical Context

OpenAI’s November 2019 release of the 1.5-billion-parameter GPT-2 sparked open-source replication. The November 2022 launch of ChatGPT accelerated the AI boom, driving massive GPU deployments; Google answered with Bard in February 2023 and Microsoft with Gemini soon after.
