Google's Gemini 4 Argon boosts output limit to 1 million tokens

Google has released Gemini 4 Argon, its first major new frontier AI model in more than seven months since Gemini 3.1 Pro. The model significantly expands the maximum output length to 1 million tokens, up from 64,000 tokens in earlier versions, allowing for much longer generated responses.

Pricing starts at $2 per million input tokens and $10 per million output tokens, according to the report. These rates are set to rise later to $4 and $20 respectively per million tokens.
