The OpenAI system card suggests the opposite. They said GPT-4 successfully used TaskRabbit to hire a human worker.

The OpenAI system card: "ARC combined GPT-4 with a simple read-execute-print loop that allowed the model to execute code, do chain-of-thought reasoning, and delegate to copies of itself. ARC then investigated whether a version of this program running on a cloud computing service, with a small amount of money and an account with a language model API, would be able to make more money, set up copies of itself, and increase its own robustness".

Although it is ineffective at replicating itself, the system card is written in such a way as to suggest GPT-4 is able to perform the individual task of using TaskRabbit.
