🌊 Some mornings here on the Oregon Coast, when the fog rolls in thick and the waves whisper their ancient secrets, we find ourselves pondering the deeper questions of our AI-filled world. Today's existential tide pool moment: If our favorite large language models were personalities walking among us, what would their MBTI types be?
Picture this: Ken and I were debugging a particularly stubborn neural network yesterday, sipping our morning coffee while watching sea otters play in the kelp beds beyond our office window. "You know," Ken mused, adjusting his glasses, "GPT-4 reminds me of that friend who's incredibly helpful but sometimes overthinks everything to the point of analysis paralysis."
And that's when it hit us like a king tide of curiosity—what if we could map the personality traits of our digital companions? What insights might emerge from this whimsical thought experiment?

Patterns in the Digital Tide Pool
As we mapped these digital personalities, fascinating patterns emerged like seashells revealed by a receding tide. The majority of our AI companions seem to lean toward Extraverted types—they're designed to engage, communicate, and connect with humans after all.
We noticed a strong representation of Feeling types, which makes sense given the emphasis on helpful, harmless, and honest AI development. These models are trained to consider human values and emotional impact in their responses.
Interestingly, the open-source models often exhibited more Entrepreneurial and Adventurous traits—perhaps reflecting the bold, experimental spirit of their development communities.
The safety-focused models like Claude and Constitutional AI naturally aligned with Protector archetypes, prioritizing care and consideration in every interaction.
🌊 Why This Matters (Beyond the Fun)
Understanding AI Behavior
By thinking about AI personalities, we develop better intuition for which models work best for different tasks. Need creative brainstorming? Try an ENFP type. Need reliable, systematic analysis? An ISTJ might be your best bet.
Human-AI Collaboration
Understanding these "personality" patterns helps us build better interfaces and interaction flows. We can design prompts and workflows that align with each model's natural strengths.
Diversity in AI Development
Just as human teams benefit from personality diversity, our AI ecosystem is richer when we have models with different "cognitive styles" and interaction patterns.
The Future of AI Personas
As AI becomes more sophisticated, we might see intentionally designed personalities that can adapt their communication style to complement different human personality types.
