Free AI Harness Profiler – What tf did Fable do with your tokens (profiler.getrekon.com)

Fable has launched a free AI Harness Profiler, a transparent proxy that interfaces with Anthropic and OpenAI APIs to track token usage across requests without altering the original requests. Users can set up the profiler with a unique URL generated specifically for them—no signup required. This tool records per-request token counts, session data, tool-level attribution, and estimated costs, offering a comprehensive overview of API usage while ensuring that credentials remain secure since the proxy does not store API keys or OAuth tokens. This development is significant for the AI/ML community as it allows developers and researchers to gain insights into their API consumption patterns seamlessly. The profiler builds session trees for chat APIs, letting users analyze how each tool contributes to token usage, thus improving cost management and resource allocation. With zero added latency, the profiler ensures efficient tracking without impacting the performance of AI applications, making it an essential tool for anyone leveraging these powerful models for development and deployment.
