Prices shown per million tokens. Models listed with two rows use long context pricing: requests whose prompt reaches the listed token threshold are billed at the higher rate for all tokens in the request.

Tools Pricing
Requests which make use of xAI provided server-side tools are priced based on two components: token usage and server-side tool invocations. Since the agent autonomously decides how many tools to call, costs scale with query complexity.
Token Costs
All standard token types are billed for the model used in the request:
- Input tokens: Your query and conversation history
- Reasoning tokens: Agent's internal thinking and planning
- Completion tokens: The final response
- Image tokens: Visual content analysis (when applicable)
- Cached prompt tokens: Prompt tokens that were served from cache rather than recomputed
Tool Invocation Costs
| Tool | Tool Name | Description | Cost / 1k Calls |
|---|---|---|---|
| Web Search | web_search | Search the internet and browse web pages | $5 |
| X Search | x_search | Search X posts, user profiles, and threads | $5 |
| Code Execution | code_execution, code_interpreter† | Run Python code in a sandboxed environment | $5 |
| File Attachments | attachment_search | Search through files attached to messages | $10 |
| Collections Search | collections_search, file_search† | Query your uploaded document collections (RAG) | $2.50 |
| Image Understanding | view_image | Analyze images found during Web Search and X Search* | Token-based |
| X Video Understanding | view_x_video | Analyze videos found during X Search* | Token-based |
| Remote MCP Tools | Set by MCP server | Connect and use custom MCP tool servers | Token-based |
† All tool names work in the Responses API. In the gRPC API (Python xAI SDK), code_interpreter and file_search are not supported. | |||
| * Only applies to images and videos found by search tools — not to images passed directly in messages. |
For the view image and view x video tools, you will not be charged for the tool invocation itself but will be charged for the image tokens used to process the image or video.
Image Search is part of Web Search and is billed at the standard Web Search rate.
For Remote MCP tools, you will not be charged for the tool invocation but will be charged for any tokens used.
For more information on using Tools, please visit our guide on Tools.
Batch API Pricing
The Batch API lets you process large volumes of requests asynchronously at a discount to standard pricing. The size of the discount varies by model. Batch requests are queued and processed in the background, with most completing within 24 hours.
| Real-time API | Batch API | |
|---|---|---|
| Token pricing | Standard rates | Discounted rates (varies by model) |
| Response time | Immediate (seconds) | Typically within 24 hours |
| Rate limits | Per-minute limits apply | Requests don't count towards rate limits |
The batch discount applies to all token types — input tokens, output tokens, cached tokens, and reasoning tokens. Batch discounts by model:
20% off standard rates
- grok-4.3
- grok-4.20-0309-reasoning
- grok-4.20-0309-non-reasoning
- grok-4.20-multi-agent-0309
Models not listed above have no batch discount.
To see a model's resulting batch prices, toggle "Show batch API pricing" on its detail page.
NOTE
The batch discount applies to text and language models only. Image and video generation are supported in the Batch API but are billed at standard rates. See Batch API documentation for full details.
Priority Processing Pricing
Priority Processing gives text requests higher scheduling priority for lower latency. Priority requests are billed at a 2x premium over standard rates.
| Standard | Priority | |
|---|---|---|
| Token pricing | Standard rates | 2x standard rates |
| Response time | Standard scheduling priority | Higher scheduling priority |
The 2x multiplier applies to all token types — input, output, cached, and reasoning. Prompt caching discounts are applied before the multiplier.
You are only billed at the priority rate when the response confirms "service_tier": "priority". If the request is served at the default tier instead, standard rates apply.
NOTE
Priority Processing is available for Chat Completions and Responses endpoints only. It is not supported for image generation, video generation, or Batch API requests. See Priority Processing documentation for full details.
Files and Collections Pricing
Files and collections stored on the xAI platform are billed based on the amount of storage used.
| Resource | Rate |
|---|---|
| File storage | $0.025 / GiB / day |
| Collection storage | $0.10 / GiB / day |
Download Costs
Downloading data from files and collections is charged at a flat rate based on the amount of data transferred:
| Resource | Rate |
|---|---|
| File downloads | $0.20 / GiB downloaded |
| Collection downloads | $0.20 / GiB downloaded |
You can view and manage your files and collections through the xAI console or the xAI API.
Usage Guidelines Violation Fee
When your request is deemed to be in violation of our usage guideline by our system, we will still charge for the generation of the request.
For violations that are caught before generation in the Responses API, we will charge a $0.05 usage guideline violation fee per request.
Billing and Availability
Your model access might vary depending on various factors such as geographical location, account limitations, etc.
