On Artificial Analysis’s intelligence ranking, OpenAI’s frontier models still beat Claude. They’re ahead by the benchmarks that have defined this industry for three years.
On Ramp’s AI Index for May 2026, Anthropic just overtook OpenAI in enterprise spending. Anthropic usage has been exploding, growing past OpenAI for the first time this month. If intelligence is what matters, this shouldn’t happen.
OpenAI is competing at the model layer. Anthropic is competing at the platform layer — and that’s where applied AI gets won. Two bets got Anthropic there. Neither shows up on a benchmark.
What this essay explores
- Why model intelligence is necessary but insufficient for winning enterprise AI adoption
- How tools and workflows give AI the ability to act on the world
- Why the competitive gradient is shifting from marginal IQ to the intelligence harness
- How platform focus differs from building applications alone
- Why benchmarks can miss the factors that determine applied AI success
The Artificial Analysis Intelligence Index shows leading models clustered at the top of the benchmark.
Key takeaway
Anthropic figured out something OpenAI didn't — and it has nothing to do with the model.
