Token Anxiety
ELI5 — The Vibe Check
Token anxiety is that creeping dread when you're deep in a conversation with an AI and you start worrying about running out of context window. Should you start a new chat? Will it remember the architecture decisions? What if you lose the momentum? It's also the fear of watching your API bill climb in real-time. Every token counts when you're paying per million.
Real Talk
Token anxiety refers to two related concerns in AI-assisted development: (1) the fear of exceeding an LLM's context window, causing degraded performance or lost conversation history, and (2) the cost anxiety of high token consumption in pay-per-token API usage. Both influence developer behavior — leading to unnecessarily brief prompts, premature conversation resets, or reluctance to provide sufficient context.
