Codex (OpenAI) is the clear winner: 8.3/10 (A-tier) versus 7.0/10 (B-tier). Tableau AI isn't a bad tool, but on every category that drives the overall score, Codex (OpenAI) comes out ahead. The tier gap is repeatable -- not methodology noise -- and the day-to-day experience reflects it.
On pricing, Codex (OpenAI) starts free while Tableau AI requires a paid plan from day one ($15 / $42 / $75+). If you're testing the waters or running an occasional workload, that gap matters more than the score differential. Codex (OpenAI) starts at $2/$10; Tableau AI starts at $15 / $42 / $75. Compare what each entry tier actually unlocks before you compare list prices -- the limits matter more than the headline number.
By use case: pick Codex (OpenAI) when developers already paying for chatgpt plus who want a coding agent at no extra cost. Pick Tableau AI when enterprise analytics teams who need production-grade dashboards and predictive insights at scale. The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap. If you're squarely in Codex (OpenAI)'s lane, the tier-list ranking and the use-case fit point the same direction; if you're in Tableau AI's lane, the score gap matters less than the fit.
Bottom line: Codex (OpenAI) is the better tool for most people right now. Pick Tableau AI only when enterprise analytics teams who need production-grade dashboards and predictive insights at scale -- that's its lane, and inside that lane it still earns its place.
