Microsoft has announced the general availability of Microsoft Copilot Cowork in Ireland as part of a global rollout. Copilot Cowork is an advanced AI agentic system designed to execute complex, long-running tasks across multiple tools and Microsoft 365 applications. It orchestrates multi-step workflows using organisational data and apps and delivers completed outcomes rather than drafts or recommendations.

Following a three-month preview in Microsoft’s Frontier early-access programme, Copilot Cowork has become the fastest-growing feature in Frontier’s history and recorded among the highest user satisfaction scores of any Copilot or agent experience. More than half of the Fortune 500 have already used Copilot Cowork, alongside organisations including Accenture, Avanade and Zurich Insurance. Early use cases include managing inboxes, investigating engineering challenges, analysing large volumes of files and identifying at-risk sales opportunities.

Copilot Cowork runs in the cloud, allowing tasks to continue independently of the user, including when devices are offline. At general availability, the system uses a multi-model approach based on Anthropic models Opus 4.8 and Sonnet 4.6. In Frontier, customers can also access GPT 5.5, with a lower-cost, fine-tuned Cowork 1 model coming soon.

Copilot Cowork is offered on a usage-based pricing model, with charges determined by model use, context retrieval, tool calls and runtime. Organisations can manage adoption through built-in controls, including spend limits and usage visibility across users and teams. The system is grounded in organisational data within Microsoft 365 and operates within Microsoft’s enterprise security and compliance framework. New partner plug-ins extend functionality and in Frontier the agent can browse the web via a local Edge browser within enterprise controls.

By moving beyond AI tools that assist with productivity, towards systems that complete tasks end to end, Microsoft Copilot Cowork marks a shift in how AI is deployed across enterprise environments.
