Don't Use /compact Until You See This $1.22 Test

Claude Code sends your entire conversation history with every request. See how this affects your token usage and session costs. The video investigates why simple interactions in Claude Code can spiral into massive token counts. Because the tool sends the full chat history with every message, a single OK command 15 minutes into a session can consume 306,000 tokens, compared to just 27,000 in a fresh session. Understanding how the context window behaves is essential for managing your AI agent costs effectively. While the price difference is not always as extreme as the token inflation might suggest, recognizing this behavior helps you decide when to restart a session to keep billing predictable. ---- Higgsfield AI — Create AI Videos & Visuals Get 10% OFF here: https://higgsfield.ai?fpr=thomas-dccf7e 🚀 DYNAMOUS AI COMMUNITY Want to learn agentic coding with live daily events and workshops?
