AI teams love saying “we use the best model” right up until you show them the invoice. Pareto from @TheUnbiasedCo tied GPT-6 Astra for the top score here: 24/30 tasks. Astra: $1.58 per successful task Pareto: $0.52 Pareto also finished faster than DeepSeek and GLM. Same top-line result. Roughly a third of the cost. No ugly speed tradeoff. Blindly routing everything to one frontier model is starting to look like expensive laziness.
