Microsoft Merges Copilot Apps, Adopts OpenAI GPT-5.6

Microsoft is consolidating its consumer and business Copilot applications, with the company set to merge the functionalities of its standalone Copilot app and Microsoft 365 Copilot by August 18, 2026, a move that coincides with the integration of OpenAI's GPT-5.6 model into Microsoft 365 Copilot to enhance enterprise productivity tools [1, 3]. This shift acknowledges the overlap between personal and professional AI use and aims to simplify Copilot's offering amidst intense competition in the enterprise AI market [1, 3].

Copilot Consolidation and Feature Changes

The merger of Microsoft's Copilot apps will result in the discontinuation of several consumer-facing AI features, including Group Chats, AI-generated podcasts, Copilot Labs experimental features, and Deep Research [1]. For professional users, Researcher will replace Deep Research [1]. The company will also remove the animated Copilot character, Mico, and migrate files generated by the standalone Copilot app to OneDrive [1]. Microsoft states the goal is to create a "simpler, more cohesive experience," following an internal memo from Microsoft EVP Jacob Andreou that emphasized the app's need to "earn the right to exist" by shedding underperforming features [1]. This consolidation mirrors broader trends in the AI app space, with competitors like Claude and OpenAI also merging features into their core offerings [1].

Enhanced Enterprise AI with GPT-5.6

Alongside the app merger, Microsoft 365 Copilot will adopt OpenAI's GPT-5.6 as its default AI model, deepening the partnership between the two companies [3]. This integration brings GPT-5.6 to Microsoft 365 applications such as Word, Excel, PowerPoint, Copilot Chat, and Cowork, aiming to improve reasoning, coding, content creation, and workflow automation for enterprise users [3]. Microsoft claims the model will deliver higher-quality outputs and use computational resources more efficiently, enabling complex tasks with fewer prompts [3].

GPT-5.6 is available in three variants: Sol for advanced reasoning and coding, Terra for balanced performance and cost, and Luna for high-volume, lower-cost workloads [3]. OpenAI has also introduced configurable reasoning modes, including Ultra, which uses multiple AI agents for complex tasks, and new API capabilities for programmatic tool calling [3].

Differentiating Microsoft's AI Tools

Microsoft offers several AI tools for business and enterprise users, each with distinct functionalities [2]:

• Microsoft Scout: An "Autopilot" agent that runs autonomously in the background on Windows 11 and macOS, integrating with Microsoft 365 apps to gather information, schedule meetings, and prepare materials [2]. It learns user work patterns through Work IQ [2].
• Microsoft 365 Copilot: An advanced version of Microsoft Copilot that accesses both internet content and a user's work data (emails, chats, documents) to provide personalized answers and assist with tasks in Word, Excel, PowerPoint, Outlook, and Teams [2]. Unlike Scout, it activates on query [2].
• Copilot Cowork: Designed for action, Cowork enables Copilot to execute tasks and workflows across Microsoft 365 based on user intent [2]. It can reschedule meetings, prepare documents, and compile company data, powered by Work IQ to learn user personality [2].

These tools are available to Business and Enterprise users through subscriptions, Copilot Credits, and usage-based billing [2].

What to watch

• August 18, 2026: Monitor the specific features that are officially discontinued for consumers and professionals as the Copilot apps merge [1].
• Enterprise Adoption: Observe how the integration of GPT-5.6 impacts the efficiency and adoption rates of Microsoft 365 Copilot among enterprise users [3].
• Competitive Responses: Watch for further moves from competitors like Google, Anthropic, and Amazon as they continue to embed AI into their own workplace productivity tools [3].

The consolidation of Microsoft's Copilot offerings and the deeper integration of OpenAI's advanced models signal a strategic pivot towards a more unified and powerful enterprise AI platform, aiming to establish a stronger competitive position in the evolving AI market.
