How to Use Grok AI for Real-Time Research and Content Ideas
Learn how to use Grok AI to get real-time answers, research topics, and generate fresh content ideas with xAI's witty conversational assistant.
Grok 4 is xAI’s reasoning model released in July 2025, priced at $3 per million input tokens and $15 per million output tokens, with real-time access to X posts and a 256K context window.
What is Grok 4?
xAI built Grok 4 around heavy reinforcement learning on reasoning traces rather than pure pretraining scale. The headline feature is tool use against live X data, which no other frontier model has natively. It also supports a thinking mode that spends more compute before answering, and a fast mode for low-latency chat. Grok 4 Heavy, a multi-agent variant, costs more and runs several models in parallel.
What features does Grok 4 have?
- 256K-token context window with vision input
- Real-time search over X posts and web results
- Reasoning mode that allocates extra compute before answering
- Grok 4 Heavy multi-agent variant for hardest tasks
- API pricing around $3/$15 per million input/output tokens
- Available via xAI API, X Premium+, and grok.com
What makes Grok 4 stand out?
- Live X data is unique; sentiment and breaking-news tasks favor it.
- Strong on math and physics competition problems.
- Heavy mode occasionally contradicts itself across parallel agents.
Who should use Grok 4?
- Tracking breaking news and reactions on X in real time
- Competitive analysis using social sentiment signals
- Math and physics problem solving with worked reasoning
- Coding assistance where web search and reasoning combine
- Summarizing long threads and posts into briefings
Quick Summary: Grok 4
- Grok 4 is xAI’s reasoning model launched in July 2025.
- API pricing is about $3/$15 per million tokens.
- It has native access to live X posts.
- Context window is 256K with vision support.
- Weakest fit: privacy-sensitive work, since X data flows through it.
