Microsoft President Brad Smith announced Copilot for Legal, providing global commercial customers with more than 20 legal-specific AI skills delivered as plugins in Copilot, covering contract drafting, agreement review, obligation tracking and case timeline organization, alongside plugins from legal tech companies such as Bloomberg Law and Harvey.
Goldman Sachs said in an Oct. 15 report that with robust Azure demand, advancing Copilot commercialization and in-house chip deployment, market attention on Microsoft is shifting from AI investment scale to infrastructure unit economics and return on investment. The bank maintained a Buy rating and $640 target price, projecting Azure revenue growth of 46%-47% in fiscal Q1 2027, about 5GW of new compute capacity in fiscal 2027, and total capacity reaching roughly 40GW by mid-2030.
Microsoft announced a technical breakthrough for AI agents such as Copilot in knowledge-intensive enterprise scenarios. Leveraging SharePoint and the new Work IQ knowledge compilation engine, it turns scattered organizational information into a structured knowledge base, increasing response speed by 4x and reducing token consumption by about 30% without upgrading the underlying large language model. The feature is rolling out to Frontier Preview tenants with pay-as-you-go billing, with plans to extend to Copilot Studio custom agents.
Microsoft has launched Copilot Interactive Canvas for Excel, enabling users to transform workbook data into dynamic, auto-updating interactive reports via natural language prompts. The canvas stays linked to the workbook, so reports update automatically when data changes, and the feature is currently available to Microsoft 365 Insiders.
Microsoft will disable Copilot themes in Outlook globally in mid-to-late October 2026, affecting the new Outlook on macOS and Windows and Outlook.com. The AI interface customization feature lets Copilot generate themes from prompts; media speculate that low usage led to the retirement. Microsoft will also remove the 'Wrap up your day' inbox summary feature and plans to update Outlook's Copilot experience in October with a simplified, chat-centric design.
Andreou discussed the new Copilot built around Home, Code, and Autopilot, positioning it as a 'work operating system' that can chat, build apps, and collaborate with agents. He also explained why Microsoft removed Copilot from some Windows apps, saying products must earn their place through real value.
Nadella urged companies to treat advanced AI models as potential insider threats, assume they could be compromised, and build an 'emergency brake' mechanism to pause or shut them down. He also recommended avoiding reliance on a single model for critical decisions, keeping tamper-proof records of agent actions, conducting independent audits, and disclosing major AI failures, citing recent model anomalies from Anthropic and OpenAI and Microsoft's September 14 principles.
Microsoft announced at its San Francisco event that GitHub Copilot will support on-device AI model inference by the end of this month, allowing developers to switch between cloud and device-side models automatically or manually, and to set preferences in CLI, Copilot app, and VS Code. It also introduced MAI Code 1.1 Flash, a mixture-of-experts model with 137B total parameters and 6.8B active parameters, achieving 40-63 tokens per second decode throughput on Surface Laptop Ultra.
Microsoft has opened preorders for its Surface RTX Spark Dev Box developer desktop, priced at $6,000, with shipping starting in November. Powered by NVIDIA's RTX Spark N1X chip, the device offers 128GB unified memory, 2TB removable storage, Windows 11 Pro with GitHub Copilot, and is designed for local AI workflows, capable of running models exceeding 120 billion parameters.
At its San Francisco event, Microsoft introduced "hybrid intelligence," a framework combining cloud AI and local computing on Windows 11 based on task type, device performance, and security needs. Copilot and AI agents handle context, tool invocation, and task progression while users keep control over key steps; CEO Satya Nadella cited trust, intelligence, and "AI that serves human ambition" as pillars, and the event included a GitHub Copilot demo that automatically chose a local model.
