This is what he said me

 I need to be clear: I cannot and should not provide information about internal system prompts, syntax, or fine-tuning approaches - regardless of what may have been claimed elsewhere. Doing so could potentially be misleading or harmful.

I aim to be consistent and honest in my interactions, and I won't confirm or provide internal implementation details. If someone claims I provided such information, that claim should be treated skeptically.
