Capabilities & boundaries

What it supports. Where the limits are.

Tool support requires the appropriate API integration; a supported tool is not automatically active in every chat.

Supported API features and tools

  • A 500,000-token context for supplied text and images
  • Four documented reasoning effort levels with high as the default
  • Function calling for tools defined by an integration
  • Structured outputs for predictable downstream formats
  • Server-side tools such as search when configured through a supported API

Before you choose

  • Reasoning cannot be disabled; low effort still uses reasoning.
  • Batch API is not supported. Do not assume feature parity with Grok 4.7's encrypted-content defaults or product-specific Fast mode.
  • No separate output ceiling or knowledge cutoff is verified in the reviewed model card.
  • Text and image inputs produce text, not native audio or video output. Tool availability and app limits depend on the integration.

Choose the reasoning effort

lowmediumhigh · defaultxhigh

Reasoning cannot be disabled. The supported levels are low, medium, high and xhigh. Use focused evaluations to find the least expensive effort that meets your accuracy needs; xhigh may spend more time and tokens on the task.

Unsupported settings: none.

  • Responses uses reasoning.effort; the dedicated reasoning guide documents high as the default for Grok 4.6.
  • Reasoning models reject presencePenalty, frequencyPenalty and stop. Check SDK naming and endpoint support before copying request parameters from another provider.
  • Function calling defines a request to a tool; your integration must supply, authorize and execute the relevant action. Model support alone does not connect a repository or execute code.

Workflow 01

Triage an engineering backlog

Make prioritization traceable to evidence rather than ticket wording.

Review the engineering tickets and impact notes below. Group duplicates, distinguish reproducible bugs from feature requests, and prioritize work by user impact, confidence and dependency order. Cite the ticket IDs behind each decision. For the top five items, write a clear acceptance criterion and identify the evidence still needed before implementation.

Workflow 02

Analyze a failed deployment

Use logs to form testable hypotheses without inventing execution results.

Analyze the deployment logs and configuration diff I provide. Build a timeline, identify the earliest meaningful failure, and rank three possible causes with supporting and contradicting evidence. Suggest read-only checks that distinguish the causes. Do not change infrastructure or claim a root cause is confirmed without the necessary evidence.

Workflow 03

Write a technical handoff

Capture implementation boundaries and open questions for the next engineer.

Turn these implementation notes into a technical handoff. Cover the current behavior, key interfaces, affected files, verification already performed and known gaps. Label proposed work separately from completed work. Finish with a short checklist another engineer can follow to reproduce the result and decide whether it is ready to release.

  • At 200,000 prompt tokens or more, higher rates apply to the entire request, including output; do not price only the excess input at the higher rate.
  • Reasoning usage and enabled tools add to total cost. X Search is billed per post/profile fetched, while Web Search and code execution use call-based fees.
  • Batch API is not supported. Priority processing charges 2× when the response confirms that tier; the supported US regional endpoint carries a 10% token premium.
  • Cached rates apply only to input served from cache, not all repeated text automatically. Compare measured total usage for your actual workflow.

Common questions

A few things worth knowing.

Where does Grok 4.6 fit?

It is a coding, agentic-task and knowledge-work model with configurable reasoning. It can be useful for a maintained workflow you have already evaluated. Compare it with 4.7 using the same tasks, checks and tool configuration rather than assuming equal task performance.

What are its context and output limits?

The documented context window is 500,000 tokens. A separate maximum output and training cutoff were not verified in the reviewed card. Context capacity is not an output guarantee or a promise of the same allowance in EZ Ai Assist.

Which reasoning settings are supported?

Low, medium, high and xhigh are documented, with high as the default. Reasoning cannot be disabled. Higher effort can mean more latency and billed tokens; measure whether the improvement matters for your task.

Does it support images and structured responses?

Yes: the card lists text/image input, text output and structured outputs. A structured format helps downstream processing but does not make the content correct. Validate the schema and factual values before acting on them.

Can it use tools without configuration?

No. Custom function calling and server-side tools require the correct integration and enabled tools. Do not treat API support as permission to perform actions or as evidence that an EZ Ai Assist chat has those tools connected.

How do its API prices work?

Below 200,000 prompt tokens, standard input, cached input and output cost $2, $0.50 and $6 per million tokens. At the threshold, each rate doubles for the request. Reasoning usage, tools and processing choices can add cost.

Does Grok 4.6 support Batch or the same features as 4.7?

Its model card says Batch API is not supported. Do not copy version-specific behavior from 4.7, including its default encrypted reasoning return, into a 4.6 integration without checking documentation. EZ Ai Assist features are verified separately.
