Hyperscaler capital expenditure discussions focus on AI infrastructure strategy. Satya Nadella emphasizes Microsoft's approach to building scalable systems serving multiple customers rather than concentrating on just one or two model companies, with CoPilot seeing enterprise adoption across real workflows.
Agenttik is a local workspace application that enables users to run AI coding sessions across multiple projects simultaneously using Claude Code, Codex, and GitHub Copilot through their official CLIs. It supports project organization, live sessions, recurring tasks, code editing tools, and usage tracking with local SQLite storage, available as desktop builds for Linux, macOS ARM64, and Windows x64.
Microsoft discontinued the COPILOT function in Excel starting September 14, 2026. The function, previously available only in preview through Insider programs, allowed users to generate AI responses directly in cells. Users can continue using AI features through the Copilot pane sidebar instead.
Microsoft is expanding Copilot with Grok models from SpaceXAI, adding SpaceXAI as a subprocessor with administrative controls. The rollout begins through the Microsoft Frontier Program in Word, Excel, and PowerPoint, with access disabled by default and unavailable in the EU, EFTA, and UK during preview.
ASU is a CLI tool that consolidates usage metrics across multiple AI agent subscription services (Claude Code, Codex, GitHub Copilot, and others) into a unified percentage-based display, enabling users and agents to track remaining quota across different metering systems.
Anthropic's AI Data Retention Tracker maps five commercial Claude model-and-tier combinations, finding that four retain user prompts by default. Claude Fable 5.1 in GitHub Copilot requires data retention to operate safety classifiers, with zero-data-retention access limited to approved enterprises through end of 2026. Anthropic's retention policies vary by surface: Enterprise conversations retain data indefinitely by default, Covered Models under Business Associate Agreements require 30-day retention with no ZDR option, and most other Copilot models operate under zero retention.
