I Am the Reason OpenAI Is Killing Unlimited Chats
Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
OpenAI is ending unlimited ChatGPT chats and merging the feature with Codex usage limits, a change that will affect heavy users who relied on free-form conversations for software development. The shift follows the rise of power users exploiting ChatGPT's support for custom MCP (Model Context Protocol) servers and OpenAI's Secure MCP Tunnel, which let them connect local tools—such as Desktop Commander for file access, code execution, and terminal commands, and CUA (Computer Use Agent) for screenshots, mouse control, and app testing—directly into regular chats. One developer described running a unified MCP server on a Windows laptop and a VPS to perform full development workflows inside ChatGPT without consuming Codex limits, illustrating the cost pressure such usage places on OpenAI. The move signals OpenAI tightening the boundary between consumer chat and developer tooling as it manages compute costs across its product lineup. Watch for how OpenAI structures the merged usage tiers, whether MCP-based workflows remain viable under the new limits, and how heavy users migrate to Codex or competing platforms.
