| Description | ||
| Summary | Gemini 4 Argon is Google's flagship reasoning model, built for complex software engineering, deep mathematical and scientific problem solving, and autonomous multi-step agents. Google trained it to keep context across long, multi-step tasks and to turn long documents mixing text, tables, charts and images into a single grounded output. It leads the Vals Index across finance, legal, coding and tax work, and supports long decode of up to 1M output tokens in a single response. | Sonar Pro Search is Perplexity's most advanced agentic search system, available only via OpenRouter. It powers the Pro Search mode on Perplexity, adding autonomous multi-step research workflows instead of single-query answers. Pricing combines token costs with a per-request fee. |
