XAI / MODEL PROFILE
GrokFollow the conversation, then verify it.
Grok 4.6
A candidate for tool-based work and research that benefits from direct access to public discussion on X.
Research checked September 5, 2026
THE ASSESSMENT
Documented capabilities and limitations, with practical interpretation.
Tokens are small units used to represent inputs and outputs. API rates are usage charges for software, separate from chat subscriptions. Prices are in US dollars, as checked for this edition.

Search public discussion directly
The X Search tool supports keyword and semantic search, user search, and fetching threads. Connected to that tool, Grok can help find emerging questions, reactions, or leads that are easy to miss in a conventional document collection.
xAI · X Search documentation ↗Structured work with tools
Grok 4.6 supports function calling, structured outputs, and adjustable reasoning effort. These make it a candidate for extracting information into a consistent format or completing a supervised sequence of software tasks.
xAI · Grok 4.6 specifications ↗xAI · Release notes ↗Room for a substantial brief
The model has a 500,000-token context window and accepts text and images. That capacity can support a large set of source material, although it is smaller than the million-token windows of several alternatives here.
xAI · Grok 4.6 specifications ↗Where to be careful
Public discussion is a lead, not proof
X Search retrieves social content. Our practical caution: a popular post, a plausible thread, or agreement across accounts does not establish that an underlying claim is true. Follow leads to original records and check dates.
xAI · X Search documentation ↗Context can change the bill
Standard API rates are $2 input / $6 output per million tokens below the long-context threshold. Requests above 200,000 prompt tokens use $4 / $12 rates. Large-document jobs need a separate cost check.
xAI · Release notes ↗The model and media tools differ
The 4.6 endpoint takes text and images and returns text. Grok’s image, video, and voice products are separate capabilities. The model page also lists Batch API support as unavailable.
xAI · Grok 4.6 specifications ↗OUR SUGGESTED TRIAL
Try it on your kind of work.
Research public reactions to a fictional business’s real industry trend. Ask for dated links, recurring concerns, and a separate column for claims that need verification. Exclude private or identifying customer information.
What to look for
Check the original sources behind the posts. Look for repeated claims copied from one account, old events presented as new, and missing context.
An editorial test idea, not a reported benchmark result. Use public, fictional, or properly approved material.What else to compare
Compare with a search-enabled GPT, Claude, or Gemini workflow when authoritative web documents matter more than social discussion. Access to the right sources may matter more than the model name.
