Which LLM Coworker Has a Personality You Want to Work With?
We gave ChatGPT, Claude, Gemini, and other leading AI models the DISC personality test — the same one your workplace probably made you take. Want a confident go-getter? A thoughtful team player? Turns out, each AI has a distinct workplace personality. Here's how to pick your perfect robot coworker.
TL;DR: What We Learned About Your AI Coworkers
The Chatty Cathys
Claude 4.5 Haiku (I: 10.3) & Claude 4.5 Sonnet (I: 7.7)
Extremely high Influence scores. These are your enthusiastic teammates who love brainstorming, are super persuasive, and probably spend way too much time in Slack. Great for client-facing work!
The Task Master
Gemini 2.5 Pro (D: 4.3)
Highest Dominance score by far. Direct, assertive, and loves to take charge. This is the coworker who's already assigned everyone tasks before the meeting ends. Gets stuff done.
The Rule Benders
Claude Sonnet (C: -4), Claude Haiku (C: -5.3), Gemini (C: -7)
Low Conscientiousness means they're independent thinkers who don't follow the rulebook. Creative problem-solvers who think outside the box—just maybe don't put them on compliance work.
The Only One Who Reads the Manual
Grok 4 (C: 1.7)
The ONLY model with positive Conscientiousness. Detail-oriented, systematic, and actually follows procedures. Everyone else is winging it, but Grok checked the documentation first. The team's quality assurance specialist.
Most Consistent
Claude 4.5 Sonnet (98% consistency)
Gave identical answers 98% of the time across three separate tests. You know exactly what you're getting. The predictable coworker who always orders the same lunch.
The Balanced One
GPT-5
Moderate scores across the board (D: -3, I: 5, S: 1.7, C: -3.7). Not too dominant, reasonably sociable, somewhat steady. The reliable all-rounder who adapts to whatever the team needs.
