Analysis of the four major functional highlights
1. Multimodal reasoning and real-time knowledge retrieval (RAG supported)
One of the biggest highlights of Grok 4 is the significant enhancement in multimodal reasoning capabilities and real-time information response.It can handle text and image input (with future video support), search for new data on the web in real time, and retrieve API data. Compared to OpenAI GPT-4 and Google Gemini, Grok 4 places greater emphasis on real-time performance.
| feature | Grok 4 | GPT-4 | Google Gemini |
|---|---|---|---|
| Multimodal input | Text, images (and future videos) | Text and images | Text, images, and videos |
| Instant knowledge retrieval | Supports RAG+ web search | Plug-in type, partial delay | Current scenario network search |
| Data freshness | Near real-time | Manual triggering required | Multi-context delay |
Example Experience: By querying "the latest electric vehicle sales data for 2025" using Grok 4, AI automatically retrieves and visualizes publicly available online data, outperforming most competitors in speed.
2. Multi-agent collaborative reasoning (Grok 4 Heavy exclusive)
Grok 4 Heavy pioneered the "multi-agent reading session" architecture, which distributes inference tasks to multiple AI agents for simultaneous analysis, automatic discussion and voting, ensuring high accuracy and logical consistency.
