Gemini 3.1 Pro
Google's flagship and the largest context window of any major commercial model at 2M tokens. Pricing is tiered: it doubles on input above 200K tokens, which matters a great deal if you actually use the window.
What that means
A worked example
Per-token pricing is hard to feel. Take a moderately chatty production workload: 100 calls a day, roughly 10,000 tokens in and 2,000 out each time. On Gemini 3.1 Pro that comes to about:
$132 / month
Before caching, batching or volume discounts, all of which move this number a long way. Illustrative only.
