Staff Software Engineer, Character.ai

Character.ai is one of the more recent entries in this increasingly crowded field that has only grown more heated since the public release of ChatGPT in late 2022. However, compared to Microsoft and OpenAI's offerings, Character.ai stands out with a more playful personality - its bots can mimic the voices of celebrities, historical persons and popular characters. This has led to users spending vastly more time interacting with Character.ai's bots compared to the competition: nearly three times longer on average than with ChatGPT, for instance.

Following a period of rapid user growth, Character.ai closed a major funding round at a valuation exceeding $1 billion. While it is currently enjoying meteoric success, in the longer term, Character.ai's challenge is to develop a funding model that will give it the staying power it will need to compete against OpenAI and other major firms in the market. A solution it is currently exploring is research-based partnerships with large companies such as Musk's xAI and Meta.
