August 7^th, 2026 in AI, Artificial Intelligence, Blog, ChatGPT, Claude
I use AI every day. Claude for most of my writing and a fair bit of my code, ChatGPT when I want a second opinion, Copilot because it’s sat there in Teams whether I asked for it or not. That’s not unusual any more, and if you’re reading this you’re probably the same. The question I keep getting asked is this: “when do you stop using those tools and start looking at Microsoft Foundry?” Short answer; when the AI…

Open the connector picker in Copilot Studio and search for Outlook. You’ll find two options: Office 365 Outlook and Microsoft 365 Outlook. Both send emails, both manage calendars, neither requires premium licensing. So why do they exist separately? Office 365 Outlook is the mature Power Platform connector.

May 27^th, 2026 in AI, Artificial Intelligence, Blog
Token costs in production can surprise you fast. That’s especially true with agentic workloads, where a single user action can fan out into five, ten, or more LLM calls under the hood. Without visibility, you won’t know there’s a problem until the bill arrives. By then, the damage is done. The good news: there are concrete, low-effort steps you can take right now. Here are four of them: 1. Set TPM limits on your deployments…

May 8^th, 2026 in Artificial Intelligence, Blog, Purple Frog Systems

The Difference Between Using AI and Integrating It
February 25^th, 2026 in AI, Artificial Intelligence, Blog, Business
