Grok (xAI)
Grok 4.3 — real-time grounding, native video input, and the cheapest frontier tier.
xAI's Grok 4.3 leverages the live data stream of the X platform for current-events knowledge that often precedes traditional news indexing. Architecturally, Grok 4.3 uses a four-agent deliberation system where internal sub-agents debate the best response before presenting it. It is the first frontier model with native video input for reasoning, and it can generate downloadable artifacts — spreadsheets, PowerPoint decks — directly from chat, at roughly 50% the input price of GPT-5.4.

Use Cases
Real-Time Market Intel
Grok's X-stream grounding tracks competitor moves, regulatory news, and breaking events ahead of traditional search.
Video Reasoning
Native video input means agents can analyse uploaded clips — call recordings, product demos, training footage — without a separate transcription step.
Analyst Artifact Output
Grok generates spreadsheets and decks from natural-language briefs, removing the manual export step in research workflows.
High-Volume Coding
75% SWE-bench at frontier-cheapest pricing — strong default for autonomous coding pipelines.

Common questions about Grok (xAI)
Real buyer and developer questions, answered. Click any item to expand.
Is Grok's real-time grounding actually useful in agent pipelines?
Yes — especially for competitive intel, news monitoring, and any workload that touches current events. It cuts the need to maintain a separate web-search or news-API tool for most use cases.
What does "native video input" mean in practice?
You can pass a video URL or upload a clip directly; Grok reasons over it without a separate transcription step. Useful for analysing call recordings, demo videos, or training content in one step.
How does the 4-agent deliberation system change my prompts?
It doesn't — that's internal to Grok. From an integration standpoint Grok is a normal LLM endpoint; you simply get measurably better creative and analytical chat outputs.
Why is Grok cheaper than GPT-5.4 if it's frontier-tier?
xAI is pricing aggressively to win share. Output quality matches frontier providers on most benchmarks; the trade-off is the platform is younger and the ecosystem (third-party tools, fine-tuning options) is smaller than OpenAI's.
