Short answer

How can I track my prompt performance?

You can use Humanloop to log model outputs and run evaluators to check for quality. This setup lets you see exactly where prompts fail or drift. You'll get a clear view of model behavior through real-time monitoring and logging.

The outcomes.

Where your data lands.

The AI handles the heavy lifting of data collection and quality checks.

LOGGING

Captured model outputs

The AI saves every interaction. You get a full history of what the model said and when.

EVALUATION

Automated quality checks

The AI runs evaluators against your logs. This identifies specific patterns of poor performance or hallucinations.

MONITORING

Real-time performance tracking

The AI updates your performance metrics. You see immediate shifts in how your prompts are performing.

HUMAN

Manual review needed

The AI flags problematic outputs for you. You decide if a prompt needs a rewrite or a new evaluator.

The workflow

What your AI does when the data arrives.

The AI moves from capturing raw text to analyzing quality automatically.

  1. Capture outputs

    The AI records the exact text generated by your model during a session.

  2. Stream responses

    The AI handles live model interactions to ensure every token is accounted for.

    call_prompt_stream

  3. Update metrics

    The AI adjusts your performance dashboards based on the latest results.

    update_monitoring

  4. Analyze quality

    The AI uses the logged data to run evaluators and find errors.

  • Log the last five outputs from my 'customer-support-v2' prompt to Humanloop.

  • Check the monitoring metrics for my 'summarizer' prompt and tell me if accuracy dropped.

  • Run the quality evaluator on the recent logs from my 'email-generator' project.

  • Stream the output from my 'creative-writer' prompt and log the results immediately.

FAQ

How this task behaves.

  • 01

    Can the AI change my prompt text in Humanloop?

    No. The AI can log data and monitor performance, but it cannot edit your saved prompt templates.

  • 02

    Will the AI delete my historical logs?

    No. The AI only has tools to log new data and update monitoring; it cannot delete existing logs.

  • 03

    How does the AI know if a prompt is bad?

    The AI uses the evaluators you have configured to check the logged outputs against your quality standards.

  • 04

    Can I use this to fix hallucinations?

    The AI helps you identify hallucinations through monitoring and logging, but you must manually update the prompt to fix them.

  • 05

    Does this work with any model?

    Yes, as long as you are using an MCP-compatible client that can call these tools.
