What do AI models and AI subscriptions cost, and are prices really falling? This page collects the numbers from the Kingy AI Price Index, a monthly record of official list prices from the AI labs, with history back to January 2024. API prices are in US dollars per million tokens, blended at three parts input to one part output. Each tier’s figure is the median across labs.
Key AI pricing statistics
- The Kingy AI Price Index (November 2026) found that a million tokens cost a median $4.00 from frontier models, $4.00 from mid-range models and $0.26 from small models, based on 25 official price listings.

Are AI prices falling?
It depends on which years you compare. Source: Kingy AI Price Index, all 35 editions. Months before September 2026 were reconstructed from archived copies of the labs’ official price pages. A tier has a median only when at least three labs had a verified price.
| Month | Frontier median | Mid-range median | Small median | Standard plan | Top plan |
|---|---|---|---|---|---|
| April 2024 | $15.00 | no median | $0.75 | $20.00 | no median |
| October 2024 | $3.00 | no median | $0.28 | $20.00 | no median |
| June 2025 | $3.47 | $0.75 | $0.26 | $20.00 | $200.00 |
| November 2025 | $3.44 | $0.80 | $0.18 | $20.00 | $200.00 |
| November 2026 | $4.00 | $4.00 | $0.26 | $20.00 | $200.00 |
- The Kingy AI Price Index (November 2026) found that the median frontier price fell 80% in six months, from $15.00 in April 2024 to $3.00 in October 2024.
- The Kingy AI Price Index (November 2026) found that the median frontier price has stayed between $2.67 and $4.66 in every month since October 2024, and in November 2026 stood 33% above its October 2024 level.
- The Kingy AI Price Index (November 2026) found that the median small-model price fell 65%, from $0.75 in April 2024 to $0.26 in November 2026, but rose 50% in the last year from a low of $0.18.
- The Kingy AI Price Index (November 2026) found that the median mid-range price rose from $0.80 in November 2025 to $4.00 in November 2026. Much of that rise comes from which models count as mid-range: the tier held GPT-5 mini and Gemini 2.5 Flash a year ago and holds GPT-6.1 Sol and Claude Sonnet 5.5 now.
Flagship AI model prices over time
The medians move partly because each lab’s lineup changes. These lines follow one lab’s top listed model at each date, per million blended tokens.
- The Kingy AI Price Index (November 2026) found that OpenAI’s flagship list price went from $15.00 (GPT-4 Turbo, April 2024) to $3.44 (GPT-5, November 2025) to $20.00 (GPT-6 Astra, November 2026).
- The Kingy AI Price Index (November 2026) found that Anthropic’s top model cost $30.00 in April 2024 (Claude 3 Opus) and $20.00 in November 2026 (Claude Fable 5.1), a fall of 33%.
- The Kingy AI Price Index (November 2026) found that Google’s flagship list price went from $3.44 (Gemini 2.5 Pro, November 2025) to $4.00 (Gemini 4 Argon, November 2026), up 16%.
- The Kingy AI Price Index (November 2026) found that OpenAI’s cheapest model went from $0.75 (GPT-3.5 Turbo, April 2024) to $0.20 (GPT-6 Luna, November 2026), a fall of 73%.

AI pricing statistics from other sources
- Mingdeng Du’s paper “Tiered Super-Moore’s Law” (arXiv, March 30, 2026) reports “an approximately 600-fold decline in token prices” over 2020 to 2026, with a price half-life of 1.10 years for economy models and 1.55 years for mid-tier models. For flagship models it reports that a steady decline fits the data poorly (R² = 0.031), which is consistent with the flat frontier median above.
How the Kingy AI Price Index measures prices
- Source: each price is read from the lab’s own official price page and stored with the passage it came from. Past months come from archived copies of those pages.
- Tiers: frontier is each lab’s most capable model, mid-range its balanced workhorse, small its low-cost high-volume model. One model per lab per tier.
- Blend: three parts input price to one part output price, per million tokens.
- Figure: the median across labs, published only when at least three labs have a verified price.
- Data: every edition and every price can be downloaded from the Index page, free to use under CC BY 4.0.
Limits and a conflict of interest
These are list prices. They leave out batch, cached-input and volume discounts, and they do not adjust for quality: a model that costs the same as last year’s may do far more. A median can move because a lab swaps the model in a tier, not only because a price changed, which is why the flagship section follows single labs. With three to seven labs per tier, one lab’s change can move a median.
Kingy AI’s research and writing are done with Claude, made by Anthropic, whose prices are in this index. Every price links to the official page it was read from.
