How to configure AI strength to approximate human ~6D in KaTrain (default AI settings) ?

[kenming]

Hi KaTrain developers and community,

First of all, thank you for the great project! I’ve been using KaTrain with the default AI and find it very useful for training and analysis.

However, when I play against the AI with 3D strength settings, it still feels more stronger than a human 3-dan player, and I can’t consistently beat it even though I am 6D on Fox Weiqi (野狐網). I would like to adjust the AI strength so that it more closely approximates a human ~6D opponent with the default AI models (i.e., without manually replacing the engine or network).

Specifically:

Which settings in KaTrain’s AI config should I focus on to get an approximate human strength level (around ~6D)?

Are there recommended AI strategy types (e.g., “Calibrated Rank Bot”, “Simple Style”, or others) that match higher amateur strength well?

Should I adjust playouts, max_time, or other config values (e.g., KataGo engine parameters) to weaken or scale down the engine strength closer to human play?

If there are known benchmarks or settings ranges for different dan/kyu ranks in KaTrain, could someone point me to them?

I’d appreciate any advice or example settings that have worked well for players around 6D strength so I can set up a fair and useful training opponent.

Thank you!
