Talent over tokens: AI models are becoming more expensive to run, and productivity gains are limited — efficient workers might be the solution to strained budgets

As AI models become more expensive to run, with costs exceeding those of actual workers, companies are facing strained budgets. Despite the promise of productivity gains through AI deployment, many firms are not seeing the expected returns. High costs associated with AI usage are leading to budget exhaustion, with examples like Uber spending its annual AI budget in a few weeks. As AI spending continues to rise, companies may need to reconsider their reliance on AI and potentially invest in efficient human workers instead.
