Can AI therapists really be an alternative to human help?

Character.ai and other bots such as Chat GPT are based on "large language models" of artificial intelligence. These are trained on vast amounts of data – whether that's websites, articles, books or blog posts - to predict the next word in a sequence. From here, they predict and generate human-like text and interactions. The way mental health chatbots are created varies, but they can be trained in practices such as cognitive behavioural therapy, which helps users to explore how to reframe their thoughts and actions. They can also adapt to the end user's preferences and feedback.
