💼 Corporate clients ignore Fable 5

Ramp published its August AI Index: Anthropic's Claude Fable 5 — 6% of tokens and 11.4% of spending in July, OpenAI's GPT-5.6 Sol — 25% and 23%. Fable 5 costs twice as much, while revenue is only 75%.

🌍 Corporate buyers are hitting a ceiling on AI spending. Advanced clients of Anthropic and OpenAI are increasingly migrating to open-source, whose lag behind the top has shrunk to a few months.

👤 Benchmarks ≠ ROI. Fable 5 shows: companies route tasks — premium models only where quality gains pay off. Spending gap: $7,400 per employee for the top 1% versus $11.95 for the median.
