ChatGPT Quiz: Test Your OpenAI IQ

ChatGPT was built by a research lab founded in San Francisco in 2015. The organisation started as a non-profit but later shifted to a capped-profit model. It is backed by major technology investors and focuses on building AI that is both capable and safe for widespread public use.

The name behind ChatGPT points to a specific type of neural network architecture that became popular in the late 2010s. This architecture changed how machines process and produce language, replacing older sequential models. The approach involves pre-training on large text datasets before being adapted for specific tasks.

ChatGPT was made available to the public during a period of rapid growth in conversational AI tools. Its release sparked widespread debate about the future of writing, education, and work. Within days of going live, it became one of the fastest-growing consumer applications in internet history.

When ChatGPT first went live, it did not run on the most advanced model available at the time. The underlying version had already been used in various tools before ChatGPT launched. It was later upgraded, but the original version was what millions of early users experienced first.

To make ChatGPT respond in ways people actually found helpful, its developers used a training method that incorporates direct input from human reviewers. Trainers ranked different responses, and those rankings shaped how the model learnt to behave. This process helped reduce unhelpful, harmful, or misleading replies over time.
