Brief

@levie frames falling AI cost-per-task (normalized by task type) as the key enabler of wider economic diffusion, describing a repeating cycle where frontier models appear costly but are followed by efficiency gains and competitive pricing that lower per-task costs. He points to Sam Altman’s 2026-07-30 GPT-5.6 price cuts (Luna, Terra) and Sol Fast mode as concrete examples.

Why it matters

@levie: The cost of AI — normalized for the type of task — falling is one of the most important drivers of broader AI diffusion; frontier models will initially look expensive because they handle more advanced tasks, but repeated cycles of efficiency and competition will reduce cost-per-task and spur adoption.

Key details

  • On 2026-07-30 Sam Altman announced major price moves for GPT-5.6: Luna cut 80% to $0.20 per million input tokens and $1.20 per million output tokens; Terra cut 20% to $2 per million input / $12 per million output; Sol added a 'Fast' API mode up to 2.5× speed for 2× the price (same intelligence).
Source evidence

The cost of AI - normalized for the type of task - coming down is one of the most important factors in being able to drive further AI diffusion in the economy.

The general trend we should expect is that frontier AI models will continue to become more capable, and will look very expensive because the tasks that they can take on are more advanced.

Then, shortly after, AI models will get more efficient or competition will drive more aggressive pricing dynamics, thus reducing the cost per task for anything other than the peak of the frontier.

This cycle will continue over and over again, which ultimately leads to tasks becoming cheaper on a like for like basis. And by doing so you will get even more AI adoption because now AI is more affordable for a wider variety of use-cases.

major price cuts today:

*80% drop for GPT-5.6 Luna, now $0.20 per million input tokens and $1.20 per million output
*20% drop for GPT-5.6 Terra, to $2/$12
*GPT-5.6 Sol gets Fast mode in the API, up to 2.5x the speed for 2x the price, same intelligence
