The output limit rises from 64K to 1M tokens. Google cites 77.9% on DeepSWE v1.1, first place on Zapier's AutomationBench with 51.3%, and 68% on CWE-bench v1 for finding and patching vulnerabilities. Internally, agents are migrating C/C++ code to Rust. Introductory pricing is $2 per million input tokens and $10 per million output tokens, rising to $4 and $20.
