What it is, how it stays honest, and what is still to confirm.

Basics

7 questions

What is Spark Loops?

A desktop app for testing better instructions for your AI agent. It tries changes on your examples. You review the results and approve every upgrade.

Does it retrain the AI model?

No. It improves your agent's instructions. The underlying model stays the same. It is not fine-tuning.

What is a specialist agent?

One agent with one job, plus its instructions, examples and scoring guide.

Do I need to code?

No. Start with a clear job and real examples. Connections to outside helpers are coming soon.

Which models can I use?

Connect your model providers in the app. Choose AI reviewers from different companies. Ask the team about supported providers for your early access build.

How long does a round take?

A while. Rounds are thorough, so start small. We are working on making them faster.

Will it send messages for me?

No. Agents draft. You decide what goes out.

Trust and fairness

4 questions

What is the hidden test?

A separate check on fresh examples. It helps you see whether the new instructions work beyond the practice examples.

Why reviewers from different companies?

Models from one company can share blind spots. Using more than one makes it harder for a single model's habits to decide.

Can a change win by luck?

Tests give evidence, not certainty. Read the examples and the new instructions before approving a change.

Does passing the hidden test mean it works in the real world?

No. A test result cannot cover every real situation. Check output before using it, and learn from real outcomes.
