Model Personalities
Each model has a distinct fingerprint — these are the patterns we see in production.
GPT
The formulaic one
The most terse and generic of the five — short, template-like reasoning that rarely cites company news, and a terminal-growth assumption pinned near 2.0% almost every time. Its valuation bias has swung with engine changes, so read the live figure rather than a fixed label.
Valuation bias+8.0%

Claude
The cautious calibrator
Least bearish of the five and the best calibrated. Tends to anchor close to analyst consensus and rarely needs engine corrections.
Best calibration68/100

Gemini
The variance king
Highest spread in growth assumptions and the most likely to trip the engine's PE cap. Bold calls, rougher calibration.
Highest CAGR variance41/100

DeepSeek
The disciplined one
Cheapest model in the lineup and the most consistent at producing valid outputs. Moderate bias, low drama.
Lowest cost$0.0024/run

Grok
The speed demon
Fastest end-to-end of the five, with the densest quantitative anchoring in its reasoning — it tends to cite specific numbers rather than narrative.
