Million-token context AI models, ranked by API price
Every tracked AI model with a context window of 1,000,000 tokens or more (approximately 750,000+ English words, or roughly 1,500 pages of text), sorted from lowest to highest input cost per million tokens. Click any model name for its full benchmark and specification profile, or click its price to view dated API price history.
One email when a frontier model ships, expands its context window, or cuts API token pricing. No noise.

1M+ token models with tiered or non-standard API pricing (1)
Models below support at least 1,000,000 tokens of context but use prompt-length price brackets rather than a single flat per-million-token rate, so they are listed separately to keep the price ranking above exact.
| Model | Provider | Context window | Published pricing | Launch date |
|---|---|---|---|---|
| Gemini 1.5 Pro | 1,000,000 tok (~750K words) | output: $5.00/M · input (≤128K): $1.25/M · input (>128K): $2.50/M |
Methodology and word-count equivalence
A model qualifies for this page when its verified context window in data/model_releases.json is at least 1,000,000 tokens (including binary-million windows of 1,048,576 tokens and extended windows up to 2,000,000 tokens). Approximate word counts use the standard 0.75 English words per token conversion (1,000,000 tokens equals roughly 750,000 words).
Prices reflect standard pay-as-you-go API rates in US dollars per million tokens (excluding 50%-off asynchronous batch queues and router pseudo-models). See the full API price history tracker or all tracked models.
