Press Kit: AI API Token Price Decay 2022-2026
Dataset summary
- Scope: 12 frontier model families across 33 priced versions (GPT-3.5, GPT-4, GPT-4 Turbo, GPT-4o, GPT-4o mini, GPT-5; Claude 1, Claude 2, Claude 3 Haiku/Sonnet/Opus, Claude 3.5 Sonnet/Haiku, Claude 4 Opus/Sonnet/Haiku; Gemini 1.0 Pro, 1.5 Pro, 1.5 Flash, 2.0 Flash; Llama 2/3/3.1; DeepSeek V2/V3; Mistral Large 2)
- Time range: 2022-11 to 2026-05 (full 42-month window)
- Geographic scope: Global (USD list pricing on standard tier)
- Method: First-party scrape of provider pricing pages on or near the effective date, with archive.org Wayback Machine snapshots cited where the live page no longer reflects the historical price

Five quotable findings
"The cost of a standard 1,000-input, 500-output AI task fell roughly 530 times between March 2023 and August 2024. GPT-4 32K cost twelve cents per task; Gemini 1.5 Flash, after its August 2024 price cut, costs about two-hundredths of a cent. The decay rate is fastest at the bottom of the price ladder, not the top."

"Claude Opus held its price for 20 months. Anthropic priced Opus 3 at fifteen dollars input and seventy-five dollars output per million tokens in March 2024 and shipped Claude 4 Opus at the identical numbers in May 2025, choosing a faster model at the same price rather than a cut. That ended in November 2025, when Claude Opus 4.5 launched at five dollars input and twenty-five output, a 67 percent cut."

"Gemini 1.5 Flash holds the price floor, and it got there through a price cut rather than at launch. Google cut it from $0.35 to $0.075 per million input tokens in August 2024, and no later model in the dataset, including Gemini 2.0 Flash, has undercut it. Google owns its TPU stack and can amortize silicon across consumer Search workloads, which lets Flash list price approach marginal compute cost rather than carrying a sales-cycle margin."

"Open-weight hosted pricing leads each closed-weight cost cut by roughly one quarter. DeepSeek V2 priced at fourteen cents per million input tokens in May 2024. Two months later GPT-4o mini matched at fifteen cents. Together AI and Fireworks publish open-weight pricing the week the weights become public, which establishes a marginal-cost reference rate that closed-weight providers then chase at the next product launch."

"Output is now eight times more expensive than input on the GPT-5 tier. GPT-3.5 was one-to-one. The widening reflects compute economics: prefill is parallelizable across the prompt while generation is sequential. Builders running output-heavy workloads (writing, reasoning, code generation) face a meaningfully smaller cost cut than the headline 530x decay implies."

Suggested coverage angles
This study lands at the intersection of AI infrastructure economics, vendor strategy, and developer tooling. Angles the data supports:
- Vendor strategy: Anthropic Opus sticky-pricing as a deliberate positioning bet.
- Compute economics: Why output is now 8x input price, and what that means for code-generation agents.
- Open-weight catch-up: DeepSeek V2 leading GPT-4o mini by 73 days, structural rather than coincidental.
- The 530x frame: Per-task cost decay numbers suitable for State of AI Report follow-on coverage and Stanford HAI AI Index citation.
- Consumer angle: "free tier inflation", and what falling AI prices mean for incumbent SaaS.
