How Grok 4 compares
The nearest models people weigh against it, and what actually separates them.
vs Grok 3 — Against Grok 3 (xAI), Grok 4 runs about 56% cheaper per token, takes 15.3x the context and answers faster. Take Grok 4 unless you specifically need what Grok 3 does better.
vs Grok 3 Beta — Against Grok 3 Beta (xAI), Grok 4 runs about 56% cheaper per token, takes 15.3x the context and answers faster. Take Grok 4 unless you specifically need what Grok 3 Beta does better.
vs Grok 3 Mini — Against Grok 3 Mini (xAI), Grok 4 costs about 90% more per token and takes 15.3x the context. Grok 3 Mini is the one to check first if the price difference matters more than the ceiling.

Grok 3 is xAI's flagship large language model, trained on a massive dataset including real-time X (Twitter) data and designed for advanced reasoning, coding, and research tasks. It competes directly with GPT-4o and Claude Sonnet 4 at a similar price point.
Verdict
A strong STEM-focused flagship with unique real-time X data access, but priced high for what it delivers versus Claude Sonnet 4 and GPT-4o.

Best for
Users who need strong reasoning and coding capabilities with access to real-time X/Twitter data for current events and social context.
Grok 3 Beta is xAI's flagship large language model, trained on a massive dataset with claimed real-time access to X (Twitter) data and strong reasoning capabilities. It competes directly with frontier models like Claude Sonnet 4 and GPT-4o across coding, analysis, and general tasks.
Verdict
A powerful but unproven flagship that earns its place for STEM and real-time social data use cases, but the beta tag means it's not yet ready to dethrone Anthropic or OpenAI at this price.

Best for
Users who want a frontier-capable model with real-time social context from X and strong STEM reasoning at a mid-range price point.
Grok 3 Mini is xAI's lightweight, budget-tier reasoning model built on the Grok 3 architecture, designed to deliver strong logical and analytical performance at a fraction of the cost of flagship models. It targets cost-sensitive workloads where reasoning quality still matters.
Verdict
A sharp budget reasoning model that earns its place when logic matters more than creativity or multimodal support.

Pricing is highly competitive at $0.30 input / $0.50 output per million tokens. Context window is 131K tokens. No vision/image input support. xAI's API platform is newer and may have availability or rate-limit considerations compared to established providers.
BudgetReasoningLightweightLow CostxAI
Best for
Developers and researchers who need solid reasoning and logic tasks at near-throwaway pricing without committing to a full flagship model.
Grok 4 costs $2 per million input tokens and $6 per million output tokens on the API. A month of 10M input and 2M output tokens runs about $32.00 at list price, before any batch or caching discounts.
What is Grok 4 best for?
Grok 4 is best for coding and research at competitive pricing with maximum context. It is a strong fit when that workflow matters more than the tradeoffs around balanced pricing and fast speed.
When should I avoid Grok 4?
You need the highest writing quality or the most reliable production-grade output — Claude wins both.
What is a cheaper alternative to Grok 4?
Grok 3 Mini (xAI) at $0.30/1M/1M input against Grok 4's $2.00/1M/1M — roughly 90% less per token all in. A sharp budget reasoning model that earns its place when logic matters more than creativity or multimodal support. Compare it first if Grok 4's pricing is the thing stopping you.
What is a faster alternative to Grok 4?
Grok 3 — balanced against Grok 4's fast, with 131k tokens of context. Worth the swap when response time is what your users notice rather than the last few points of reasoning depth.
