Since the agent autonomously decides how many tools to call, costs scale with query complexity.--### Token Costs--All standard token types are billed at the rate 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 | Description | Cost / 1k Calls | Tool Name |-|---|---|---|---|-| Web Search | Search the internet and browse web pages | $5 / 1k calls | `web_search` |-| X Search | Search X posts, user profiles, and threads | $5 / 1k calls | `x_search` |-| Code Execution | Run Python code in a sandboxed environment | $5 / 1k calls | `code_execution``code_interpreter` |-| File Attachments | Search through files attached to messages | $10 / 1k calls | `attachment_search` |-| Collections Search | Query your uploaded document collections (RAG) | $2.50 / 1k calls | `collections_search``file_search` |-| Image Understanding | Analyze images found during Web Search and X Search* | Token-based | `view_image` |-| X Video Understanding | Analyze videos found during X Search* | Token-based | `view_x_video` |-| Remote MCP Tools | Connect and use custom MCP tool servers | Token-based | Tool name is set by each MCP server |--Web Search$5 / 1k calls--Search the internet and browse web pages--`web_search`--X Search$5 / 1k calls--Search X posts, user profiles, and threads--`x_search`--Code Execution$5 / 1k calls--Run Python code in a sandboxed environment--`code_execution``code_interpreter`--File Attachments$10 / 1k calls--Search through files attached to messages--`attachment_search`--Collections Search$2.50 / 1k calls--Query your uploaded document collections (RAG)--`collections_search``file_search`--Image UnderstandingToken-based--Analyze images found during Web Search and X Search*--`view_image`--X Video UnderstandingToken-based--Analyze videos found during X Search*--`view_x_video`--Remote MCP ToolsToken-based--Connect and use custom MCP tool servers--Tool name is set by each MCP server--All tool names work in the Responses API.

Batch requests are queued and processed in the background, with most completing within 24 hours.--| | Real-time API | Batch API |-|---|---|---|-| Token pricing | Standard rates | 20%-50% off standard rates |-| 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. To see batch pricing for a specific model, visit the model's detail page and toggle "Show batch API pricing".--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.--## Files and Collections Pricing--Files and collections stored on the xAI platform are billed based on the amount of storage used. These charges will take effect starting on April 20th, 2026.--| 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.- ## Additional Information Regarding Models @@ -249,4 +88,5 @@ For violations that are caught before generation in the Responses API, we will c - Chat models - No role order limitation: You can mix `system`, `user`, or `assistant` roles in any sequence for your conversation context.+ - `logprobs` and `top_logprobs` are not supported by models `grok-4.20` and newer.

You can now use cached prompt tokens to incur less cost on repeated prompts. By reusing stored prompt data, you save on processing expenses for identical requests. Enable caching in your settings and start saving today!--The caching is automatically enabled for all requests without user input. You can view the cached prompt token consumption in the `"usage"` object.--For details on the pricing, please refer to the pricing table above, or on xAI Console.--Did you find this page helpful?--Last updated: May 6, 2026+Last updated: May 15, 2026
