xAI Grok 4.6 is the newest flagship Grok model, positioned by xAI as a frontier model for coding, agentic tasks, and knowledge work, with a 500K-token context window (split longer content into parts). Use the reasoning-effort dropdown (low/medium/high, default high) and the thinking-display option to tune how deeply it thinks. Web search and image/document upload are supported. Grok's style is livelier and less formal, which suits brainstorming, marketing copy, and casual assistant scenarios. If you need to search the web for information, please turn on the "Web Search" switch. Maximum context window (input and output combined): about 500,000 tokens. Maximum total upload size per request: 256MB (all files and message content combined). Accepted document formats: pdf, docx, xlsx, pptx, txt, csv (file content is provided to the model as extracted text). Accepted image formats: jpeg, jpg, png. Maximum size per image: 20MB. Image dimensions: at least 200 pixels per side. Maximum image resolution: 36,000,000 pixels in total. Output content formats: Text
