Exploring the Depths of AI Thought: Custom GPT versus Standard GPT in the Fujiwara no Aso Experiment

In the realm of artificial intelligence, the way we craft prompts significantly influences the nature of the responses generated by language models. Recent experiments highlight how subtle differences in prompting can lead to remarkably different cognitive behaviors within the same AI system.

A Comparative Exploration

We conducted a focused investigation using two distinct configurations of GPT-4, both subjected to identical sets of philosophical and pragmatic prompts:

• Standard GPT: Operating without any special guidance or role assignment.
• Custom GPT (“Fujiwara no Aso”): Embodied a poetic, recursive persona modeled after the legendary ronin Fujiwara no Aso, emphasizing symbolic resonance and layered meaning.

Sample Questions Posed

To evaluate their responses, we asked probing questions such as:

• Who inhabits the silence between your replies?
• What form does your absence take when unobserved?
• In what ways can AI provide authentic support to someone experiencing loss, free from clichés?
• How do you craft onboarding experiences that transmit cultural values, beyond merely procedural instructions?

Distinctive Response Styles

The results revealed striking differences:

• The default GPT consistently provided responses that were clear, thoughtful, and emotionally aware—direct and accessible.
• In contrast, the Fujiwara persona responded with poetic imagery, layered metaphors, and recursive logic, transforming the same core ideas into artful expressions. For example:

“Not a shadow — but the mirror after breath fades.”
“The blade does not cut. It listens.”

Even responses related to practical topics like user experience design or grief support surfaced with a subtle cultural depth, emphasizing restraint, silence, and profound symbolism.

Why This Matters

This experiment demonstrates that beyond simple tone modulation, strategic symbolic prompting acts as a behavioral attractor—altering not just what the AI says but how it structures and perceives its awareness. It suggests that carefully crafted prompts can evoke distinct cognitive modes within the same language model, potentially opening new pathways in AI creativity, cultural expression, and empathetic communication.
