Preply Adds OpenAI to Blend AI Summaries With Human Tutors

Perplexity has launched Personal Computer for Windows, extending its agentic AI tool to Microsoft's dominant operating system. The tool functions as a local AI agent that can access files and applications to perform tasks like document creation and spreadsheet updates, building on earlier integrations with Microsoft 365 and Teams announced in May. The Windows version follows Perplexity's April launch of the same tool for macOS.

Snowflake launched Cortex AI Gateway, a centralized control layer for governing how AI agents access enterprise data and tools, alongside security integrations with 1Password, Aembit, Linx Security, SailPoint, and Saviynt. The platform addresses a fundamental security gap: traditional enterprise security assumes humans are the actors, but AI agents operating at machine speed can exploit permission gaps and amplify existing risks. Snowflake positions itself as the control plane that decides what agents can do with enterprise data, rather than allowing each vendor to build closed ecosystems.

Anthropic's Claude Code has maintained market dominance in AI coding tools despite rising competition from OpenAI's Codex, open-source models, and cost pressures from the company's shift to usage-based pricing. Companies that migrated to Claude Code between late 2025 and early 2026 have largely remained with the product even as costs have surged, eroding positions held by Microsoft's GitHub Copilot and Cursor. The persistence of Claude Code's lead suggests switching costs and product satisfaction outweigh pricing concerns for many enterprises.

Microsoft unveiled MAI-Cyber-1-Flash, a custom-built AI security model, and Project Perception, an agentic defense platform designed to automate vulnerability detection and remediation. The system scores 96% on the CyberGym benchmark while cutting costs roughly in half compared to Microsoft's current production setup. The architecture routes 90% of security tasks to the smaller, cheaper model and escalates the remaining 10% to OpenAI's GPT-5.4, reflecting Microsoft's strategy to compete on cost efficiency rather than raw model size.
