A mature conversational model for complex reasoning and code analysis
grok-4 is xAI's Grok 4 reasoning conversational model, suitable for tasks that require breaking down conditions, analyzing code, comparing approaches, and continuing follow-up questions. It is better suited to analysis based on clearly defined materials than to treating a single response as an automated execution program or real-time information query.
Choose an available protocol for this model. OpenAI SDK uses a Base URL ending in /v1; Anthropic SDK uses the root URL. See each guide for protocol-specific parameters, tools and response formats.

Core capabilities
Learn what grok-4 can bring to your work.
Break complex problems into verifiable steps
Grok 4 focuses on reasoning-based conversation. For problems with multiple conditions, you can ask it to first organize the known conditions, then compare hypotheses, explain the reasoning, and provide a conclusion. It is suitable for mathematical discussions, technical solution trade-offs, and business rule analysis; clearly stating the conditions and acceptance criteria is more helpful for checking answers than simply asking it to “think deeply.”
Continuously analyze and revise code
After submitting code snippets, error messages, and expected behavior, you can ask grok-4 to help identify issues, propose modifications, and explain their impact. Continuing to provide test results helps gradually narrow the scope of investigation. It delivers code and analysis suggestions; compilation, testing, and deployment must still be completed in the actual development environment.
Preserve the basis for trade-offs in multi-condition problems
For technical and business rule questions, provide hard constraints, existing data, and acceptable trade-offs together. Ask each response to explain how the conditions affect the recommended approach, then supplement with real materials to continue the discussion, which helps avoid receiving only generic advice.
Applicable Scenarios
Start from specific tasks and find where the model can play a role.
Technical Troubleshooting
Input relevant functions, error stacks, runtime environment, and attempted fixes, and let grok-4 organize possible causes, suggest troubleshooting order, and generate modification drafts. Deliverables can include problem explanations, patch suggestions, and test checklists; then bring actual test results back into the conversation to continue validation rather than directly accepting the initial judgment.
Solution Review and Rule Analysis
Provide business objectives, constraints, and candidate solutions, and ask the model to compare them using consistent criteria while identifying which conclusions depend on additional assumptions. Suitable for creating technical selection documents, rule conflict lists, or review outlines. Important data should be provided along with the question so that discussions focus on facts in the materials and verifiable decision-making bases.
Continuous Learning and Problem Explanation
Input questions, your own solution process, and where you got stuck, and let grok-4 explain key concepts, check steps, and provide targeted practice suggestions. Through continuous follow-up questions, you can move from intuitive explanations to formulas or code expressions. The deliverable is an explanation and practice draft; before formal use, calculation results and boundary conditions should still be checked.
How to Choose This Model
Select based on task complexity, input materials, and expected results.
Existing Grok 4 Workflow: Prioritize Task Fit Evaluation
If an application has already established processes around grok-4's response style, prompts, and test sets, it can continue using it for reasoning, code analysis, and content tasks. Grok 4.7 is a different version and its long context or reasoning configuration should not be directly applied to Grok 4. Whether to upgrade should be based on comparisons of results from the same set of real-world tasks.
Preserve Evidence Behind Results
Keep the versions of materials submitted to grok-4 and the actual responses, distinguishing between original facts, model suggestions, and actions already completed by the application. Before structured results enter the system, check required fields, value types, and business rules to avoid turning missing information directly into confirmed records.
Arrange inputs first, then connect them to the corresponding application workflow.
Prepare Input
Prepare candidate solutions, hard constraints, acceptable trade-offs, and existing measurement data.
Organize Calls and Follow-up Processes
Explicitly select grok-4 in Chat Completions requests, and organize the background, materials, and output requirements for this request into messages. First use a task with a clearly defined scope to check the response, then put actual review or testing feedback into the next round of messages.
Design tasks directly from the following inputs and acceptance criteria.
Suggested Task
Please check each solution one by one to determine whether it meets the constraints, list the evidence, failure conditions, and experiments that still need to be completed in a table, and then explain the recommendation order.
Key Checks
Review every constraint and number, and continue gathering information for judgments with insufficient evidence; complex reasoning still requires validation with real-world data.
Usage Boundaries
Before formal use, understand the scope of output quality and capabilities.
Grok 4's reasoning responses may still be based on incorrect assumptions. Mathematical proofs, code fixes, and complex rule judgments should retain inspectable intermediate evidence, and conclusions should be verified using tests, calculations, or human review; a detailed response does not mean every derivation is correct.
Basic conversations do not automatically gain access to real-time news, market quotes, or the latest software changes. When recent facts are involved, provide dated materials or obtain information through a session workflow with search tools; the model's confident tone cannot be treated as proof that information has been updated.
Image input is used to assist with image-and-text analysis, not image generation; function calling also does not directly execute programs. File reading and tool operations require the appropriate entry points and permissions, and fields such as audio and search in shared requests cannot be understood as features that Grok 4 necessarily has.
Frequently Asked Questions
Answers to common questions about using grok-4.
Are grok-4 and Grok 4.7 the same model?
No. grok-4 is the invocation ID for Grok 4, while Grok 4.7 is a different version. Evaluate their performance for your tasks separately; do not treat Grok 4.7's context length, reasoning configuration, or new features as specifications of Grok 4, and do not judge migration benefits based solely on version names.
How can I make grok-4 analyze code better?
Provide the code, error messages, expected results, and runtime environment, and specify which parts cannot be changed. You can first ask it to identify the cause, then generate a repair draft and test checklist. After actual testing, bring failed cases back into the same conversation for further analysis instead of confirming the fix based only on a textual explanation.
How do I call grok-4 with the standard API?
Submit model=grok-4 and messages to /v1/chat/completions. Read standard results from choices[].message.content; for streaming calls, obtain incremental results through stream. Use this platform's API Key and configure the complete base URL according to the SDK you use.
Can grok-4 directly look up the latest information?
Simply sending a question does not mean a real-time search is performed. Recent events should be analyzed together with search tool results or the latest materials you provide. For answers requiring timeliness, request that source dates be noted and keep factual statements separate from model inferences for easier subsequent verification.
Is the business operation complete after grok-4 returns a tool call?
Not necessarily. Function calls in the chat interface specify the function and parameters to use; the application still needs to validate, execute, and return the results. When using a conversational tool workflow, also check permissions and execution status; for operations involving writing, publishing, or deletion, retain explicit authorization and failure handling.
