A Python script called BudgetHarness has been developed to demonstrate how token counts in LLM agent interactions can be misleading. The script, which uses only standard Python libraries, allows users to call any OpenAI-compatible chat endpoint and log token usage per call. By running a simple experiment with three different prompts for the same task, the harness reveals that token counts vary significantly based on factors like the inclusion of system prompts, even when the core task remains identical. This highlights that direct comparison of token usage between different agent configurations can be unreliable. AI
