OpenAI released GPT-5.5 on April 24, its smartest model yet, just six weeks after GPT-5.4, with major gains in agentic coding, computer use and unified multimodal processing.
GPT-5.5 processes text, images, audio and video in a single architecture, with strong gains in agentic tasks. Available to Plus, Pro, Business and Enterprise users via ChatGPT and Codex.
Six-week release cycles mean any AI workflow you build today will run on a meaningfully better model within two months, making "wait and see" a losing strategy.
Australian marketing teams using ChatGPT for content, research or reporting get immediate capability upgrades, but need to audit prompt libraries and workflows each cycle to capture the gains.
Content teams, marketing analysts and anyone using AI for multi-step tasks like campaign reporting, brief writing or competitive analysis.
Teams that set up AI workflows once and never revisit them will underperform teams that optimise for each model generation.
Re-test your top five AI workflows on GPT-5.5 this week to measure quality and token efficiency gains.
