1. Conceptual Role
A Chief AI Officer (CAIO) is a C-suite executive responsible for an organisation’s AI strategy, implementation, governance, ethics, security, reliability, risk management and exploitation. It’s a rapidly-growing role, especially since the LLM boom. The number of CAIOs globally has nearly tripled over the past five years.(Financial Times, Wikipedia)
2. Virtual / Fractional CAIO
A Virtual CAIO (sometimes abbreviated as vCAIO or expanded as Virtual Chief AI Officer) is essentially an outsourced or fractional version of that role. It’s aimed at companie, especially smaller ones,that need AI leadership and direction but can’t justify hiring someone full-time.
Here are a few examples:
