Apollo's chief economist says AI has delivered zero payoff outside tech. His charts show flat averages for 493 companies. Flat on average is not zero for everyone.

Revenue per worker and margins are flat for the S&P 493, and productivity growth is near nil. That supports 'no visible payoff yet'. It does not measure AI, and an Atlanta Fed survey finds small positive gains that lag in the revenue numbers.

The reality check

Apollo's charts show revenue per worker and margins flat for the S&P 493 and productivity growth near nil. Other data agree nothing shows up yet in the aggregates. But the charts are averages that do not separate AI from anything else, and an Atlanta Fed survey of executives finds positive gains that are slow to reach revenue. THE VERDICT: Needs context. 'Not visible yet' holds. 'Zero' overreaches.

Why care? If you are deciding on AI spend, the honest read is that broad payoffs have not shown up in big-company averages yet. That is a reason to measure your own results, not proof there are none.

Take this with youApollo's charts show flat revenue per worker and margins for the S&P 493. That fits no visible payoff yet, but the charts do not measure AI itself.

Next: Cheaper, mostly closed

IBM's CEO says open weights are 90% as good for 10% of the cost. In Ramp's spending data, only 6.4% of AI-spending businesses pay for open-source models.

The cost pressure is real. But spending data says most of the shift goes to cheaper closed models, the 90% has no named benchmark, and IBM sells the racks.

The reality check

a survey shows open-weight token share rising to 34%, but Ramp's spending data says most growth goes to cheaper closed models and only 6.4% of AI-spending businesses pay for open-source ones. No benchmark is named for the 90%, and IBM sells the on-premises racks. THE VERDICT: Needs context. Cheaper models are winning; open weights are one slice.

Why care? The saving is real but comes mostly from smaller models, which closed vendors also sell. Before buying 2 or 3 racks, price a small closed tier against an open model on your own work.

IBM'S OPEN-WEIGHT CLAIM: Where the money goes

Next: Open on a promise

Open-source AI is a month behind the best, says the post going round. The model that closes the gap has no downloadable weights yet, and Artificial Analysis lists it as proprietary.

The 55 score is real and comes from Artificial Analysis. The 'month behind' is ModelCompare's own arithmetic, and it counts Kimi K3.1 Pro as open because Kimi promises weights by Nov 4.
