Everyone’s talking about MCP, but nobody shows you the monetization side. In this one I break down Xpack, a free tool to spin up your own MCP server or even host a full marketplace (with Stripe payments).

NO CODE If you’ve been curious how to actually profit from MCP servers, this is the starting point. https://youtu.be/V_LHDy4CRYQ

OpenAI has rolled out GPT-4.1 and GPT-4.1 Mini directly into ChatGPT. But are they worth the hype? I put them to the test with real-world prompts—and the results were surprising. - Instruction Following: GPT-4.1 excels at following detailed prompts, making it ideal for agentic workflows. However, it requires well-structured prompts to shine. - Performance: In side-by-side comparisons, GPT-4.1 was faster and more efficient than GPT-4 Mini High, delivering markdown-formatted reports swiftly. - Coding Capabilities: While GPT-4.1 handled data analysis impressively, it struggled with complex coding tasks, sometimes failing to complete them. - Prompting Guide: OpenAI's extensive prompting guide emphasizes the need for explicit instructions, planning, and reflection to get the best results from GPT-4.1.
