Microsoft makes Copilot Cowork generally available worldwide with multi-model support

Microsoft made Copilot Cowork generally available worldwide, with Satya Nadella announcing it on LinkedIn (9,623 likes) and X: 'Every organization can put long-running agents to work on complex, multi-step tasks, grounded in your organization's unique knowledge and know-how.' The GA adds multi-model support — the architectural feature that makes Microsoft's exploration of cheaper models like DeepSeek V4 feasible — plus plugin extensibility, browser automation, and cost-management controls.

Copilot lead Charles Lamanna detailed the rollout, noting months of Frontier-preview feedback shaped GA improvements across model choice, extensibility, and cost. The cost-management emphasis is telling: Microsoft confirmed Cowork customers pay based on compute usage, making agentic spend a first-class concern — the same 'tokenmaxxing' pressure echoing across OpenAI's Enterprise spend controls and AWS AgentCore.

This is Microsoft's flagship answer in the agent-platform race against AWS's AgentCore (also hitting GA milestones this week) and Google's orchestration efforts. The multi-model, plugin, and browser-automation combination positions Cowork as a general-purpose enterprise agent runtime grounded in Microsoft 365 data — its key distribution advantage.

The skeptical lens: long-running autonomous agents grounded in corporate knowledge raise data-governance and reliability questions, and usage-based billing introduces cost unpredictability that the new controls only partly tame. Microsoft also released Azure Cobalt 200 VMs claiming 50% performance gains for agentic workloads and set a new LLM-training performance record, underscoring the full-stack push behind Cowork. Watch enterprise adoption and whether multi-model routing meaningfully cuts customer bills.
