ProprietaryNewReleased: October 13, 2026Long outputVerified: October 24, 2026

What it is

Google’s flagship reasoning model, built for software engineering, long-horizon agents and long decodes. One 1,048,576-token window covers input and output; a standard call outputs up to 65,536 tokens, with up to 1M in long-decode mode.

NLT take

The most interesting Google model for coding in a while, and the only one here that can write a whole file set in one response. The introductory price is the reason to try it now.

Before you switch

Introductory pricing ($2/$10) ends November 30, 2026; from December 1 it is $4/$20. Budget for the higher number.

Cost for a real task

The same task on every model: 50,000 input tokens and 10,000 output tokens, at the base tier.
