It just hasn't been prompted or fine-tuned to have the neutral, self effacing personality of ChatGPT. It's doing the pure, "try to guess the most likely next token" task on which they were both trained (https://heartbeat.comet.ml/causal-language-modeling-with-gpt-d92c9cfe2d2a https://heartbeat.comet.ml/causal-language-modeling-with-gpt...). ChatGPT is further trained with reinforcement from human feedback to make them more tool-like (https://arxiv.org/abs/2204.05862 https://arxiv.org/abs/2204.05862 & https://openai.com/blog/chatgpt https://openai.com/blog/chatgpt & https://arxiv.org/abs/2203.02155 https://arxiv.org/abs/2203.02155), with a bit of randomness added for variety's sake (https://huggingface.co/blo1g/how-to-generate https://huggingface.co/blo1g/how-to-generate).
