xAI Grok API Pricing 2026: Token Rates by Model

The xAI API is the developer access point for all Grok models. Pricing is per million tokens (input and output billed separately).

Grok API Rates (Per Million Tokens)

What Each Grok API Model Is For

Grok 4.3 is xAI's flagship model via API. At $1.25/$2.50 per million tokens with a 1M token context window, it is the most capable and context-rich option. A 100,000-token document costs $0.125 to process — competitive with Claude Sonnet 4.6 and significantly cheaper than GPT-4o.

Grok 3 offers the same $1.25/$2.50 rate as Grok 4.3 but with a 131K context window instead of 1M. Use it when you do not need the extended context but want frontier model quality.

Grok 3 Mini at $0.30/$0.50 is the mid-tier option — capable enough for summarisation, classification, and structured extraction at roughly a quarter of the flagship model's cost.

Grok 4.1 Fast at $0.20/$0.50 is xAI's cheapest capable model. At $0.20 per million input tokens, it competes directly with GPT-4o Mini as a high-volume, lower-complexity workhorse.

Cache Read at $0.05 per million tokens lets you reuse cached context (system prompts, large documents) for a fraction of the input rate. This is the same prompt caching concept Anthropic offers and dramatically reduces costs for applications with repeated context.

Free xAI API Developer Credits

All xAI API developers receive $175 per month in free credits. For small applications, prototypes, or testing, this means genuinely free API access within the credit limit. At $1.25/M input tokens on Grok 4.3, $175 covers approximately 140 million input tokens per month before any charges apply.

Grok API vs OpenAI vs Anthropic: Price Comparison

Here is how Grok API pricing compares to the equivalent models from OpenAI and Anthropic at identical capability tiers.

Low-Cost Models

Grok 4.1 Fast undercuts Claude Haiku 4.5 significantly. It costs more than GPT-4o Mini on input but less on output — net cost depends on your output-to-input ratio.

Frontier Models

Grok 4.3 is the most affordable frontier model in this comparison. At $1.25/$2.50, it is half the price of GPT-4o on input and one-sixth the price of Claude Opus 4.7 on output. For output-heavy applications (long-form generation, detailed analysis), the output cost gap is especially significant.

The trade-off: Grok's benchmark performance on complex reasoning tasks is competitive but varies by task type. GPT-4o and Claude Opus 4.7 outperform Grok 4.3 on certain code generation and multi-step reasoning benchmarks. For applications where reasoning quality is the bottleneck, test before committing.

SuperGrok Consumer Plans: Full Breakdown

For non-developers who want Grok as an AI assistant, xAI offers four subscription tiers.

Free Tier

Anyone with an X account gets basic Grok access for free.

Free tier includes:

• Approximately 10 prompts per 2-hour rolling window
• Limited web search via real-time X and web data integration
• Access to a lighter Grok model
• Restricted image generation

Grok's free tier is more limited than Claude's free tier and ChatGPT's free access. The unique advantage is real-time X data — even free users can query Grok about trending topics, recent X posts, or breaking news. No other AI assistant offers this natively.

SuperGrok Lite — $10/Month

SuperGrok Lite launched in March 2026 as an entry-level paid tier.

SuperGrok Lite includes:

• Basic AI image generation (Aurora model)
• Basic AI video generation
• Access to one AI agent
• Higher message limits than free (exact cap not publicly specified)
• Standard Grok model access (not Grok 4.3)

Best for: Casual users who primarily want AI-generated images or short video clips and need more headroom than the free tier provides.

SuperGrok — $30/Month ($300/Year)

SuperGrok is xAI's primary consumer product and the direct competitor to Claude Pro ($20/month) and ChatGPT Plus ($20/month).

SuperGrok includes:

• Grok 4.3 — xAI's flagship model
• 128K token context window
• DeepSearch — real-time web and X search integrated into responses
• Big Brain mode — extended compute reasoning for complex problems
• Think mode — step-by-step reasoning shown before answers
• Voice mode
• Unlimited AI image generation (Aurora model)
• Approximately 30 messages per 2-hour window on Grok 4.3

The X data advantage: SuperGrok's defining capability is DeepSearch with live X integration. For journalists, PR professionals, market researchers, political analysts, and social media managers, this is a genuine capability gap over competitors. No other AI assistant provides this depth of real-time social platform data.

The price premium: At $30/month, SuperGrok costs 50% more than Claude Pro and ChatGPT Plus. The extra $10/month primarily pays for the real-time X data integration. If that is not valuable to your work, Claude Pro or ChatGPT Plus delivers comparable general reasoning at a lower price.

Message limits: The 30-message-per-2-hour cap on Grok 4.3 is more restrictive than ChatGPT Plus (approximately 150 messages per 3 hours on GPT-4o). Heavy users will hit it.

X Premium+ — $40/Month

X Premium+ bundles SuperGrok capability with an ad-free X experience.

X Premium+ includes:

• Full Grok 4 access (same capability as SuperGrok, slightly older model than Grok 4.3)
• Ad-free X browsing
• X Premium+ account badge and features
• Creator revenue sharing eligibility
• Priority customer support on X

Best for: Heavy X users who want both an AI assistant and a better X experience. If you spend significant time on X and would pay for the ad-free experience separately, Premium+ bundles the value efficiently at $40/month.

Skip it if: You primarily want the AI capability and use X infrequently. SuperGrok at $30/month gives you the same AI features for $10 less.

SuperGrok Heavy — $300/Month

SuperGrok Heavy is xAI's premium tier for professionals requiring maximum capability.

SuperGrok Heavy includes:

• Full Grok 4.3 with parallel compute (test-time compute scaling)
• 256K token context window (double the standard SuperGrok)
• Maximum rate limits — significantly more messages per hour than standard SuperGrok
• Priority processing
• Full access to Grok's most compute-intensive reasoning modes

Best for: Researchers, developers, and enterprise professionals running Grok on book-length documents, large codebases, or extended multi-step analysis sessions where both the context size and message throughput matter. The 256K context window is the largest offered in any Grok consumer tier.

Cost reality check: At $300/month — 10x the cost of standard SuperGrok — this is for organisations or power users who consume Grok at very high volume and need both the extended context and the throughput headroom.

Grok's Key Features Explained

DeepSearch

DeepSearch is Grok's integrated real-time web and X search tool. Unlike ChatGPT's web browsing or Perplexity's search results, DeepSearch sources live X posts as primary data alongside broader web crawl.

Unique use cases this enables:

• Tracking breaking news as it develops on X in real time
• Understanding current public sentiment on a brand, political topic, or event
• Researching what practitioners are saying in specific technical communities right now
• Monitoring competitor announcements and community reaction

No competitor replicates this. It is Grok's clearest product differentiation.

Think Mode and Big Brain Mode

Think mode displays Grok's step-by-step reasoning before the final answer — equivalent to Claude's extended thinking or GPT-4o's reasoning mode. Useful for complex problems where transparency into reasoning matters.

Big Brain mode allocates additional compute for harder problems: multi-step mathematics, complex code generation, nuanced analysis with multiple constraints. Available on SuperGrok and above, at the cost of slower responses.

Aurora Image Generation

Grok's image generation uses xAI's Aurora model. SuperGrok includes unlimited image generation with no extra cost. Quality is competitive with DALL-E 3, with particular strength in photorealistic and stylised outputs.

Grok vs Claude Pro vs ChatGPT Plus

Grok's advantages: Real-time X platform data, unlimited image generation at no extra cost, frontier API pricing (Grok 4.3 at $1.25/$2.50 vs GPT-4o at $2.50/$10.00).

Claude's advantages: Claude Code for software development, extended thinking quality, writing and reasoning benchmarks on complex tasks, prompt caching savings.

ChatGPT's advantages: Price per message at the Plus tier ($20 vs $30), Code Interpreter for data analysis, broader third-party integrations and plugin ecosystem.
