Yes, however it is important that you understand the conditions under which you may use AI to be eligible. The 2025 Olive Cotton Award conditions of entry state:
Artificial intelligence (AI) tools may be used in the creation of the photographic portrait, but AI-generated content must not constitute a substantive part of the final artwork. Entrants using generative AI tools in the creative process must provide details on how and to what extent the AI was used in the creation of the artwork and the specific tools used.
The entrants must read the information sheets on AI and copyright (links below) prior to submitting their artwork(s), and warrant that all required consents have been obtained, including but not limited to any copyright or intellectual property material, names, images and/or likeness contained in the AI tools used. The Gallery reserves the right to exclude any entry considered to contain substantive AI-generated content.
