SpaceXAIGrok 4.6
SpaceXAI's frontier text-and-image model for coding, agentic tasks, and knowledge work, with direct web, X, and code tools.
Plain-English overview
What Grok 4.6 actually is
Grok 4.6 provides configurable reasoning, a 500K context window, and tool access that includes web search, X search, and code execution. It supports both Responses and Chat Completions-style integrations.
The published base price applies below a 200K-prompt threshold. Large-context agent loops should use stable conversation routing and caching where possible, because cache misses and long-context pricing can change the economics.
Good fit for
- Coding agents with live web or X context
- Tool-heavy knowledge workflows
- Teams already building on OpenAI-compatible APIs

The facts that matter for text models
These are provider-published specifications, not Cody benchmark scores. Follow the linked sources for current limits and endpoint-specific exceptions.
- Context window
- 500K tokensMaximum combined prompt and working context documented by the provider.
- Maximum output
- No published text capProvider-published response limit, where available.
- Knowledge cutoff
- January 2026Latest reliable knowledge date explicitly published by the model provider. Search and connected tools can retrieve newer information but do not change the model's built-in cutoff.
- Input price
- $2 / 1MCurrent standard list price per million input tokens unless noted.
- Output price
- $6 / 1MCurrent standard list price per million output tokens unless noted.
- Inputs
- Text, imageMedia types accepted by the listed model endpoint.
- Tools & agents
- Functions, web/X search, code executionSelected native tools and agent-building capabilities, not an exhaustive list.

Estimate your cost
Set your usage. Your estimate updates as you type.
Example: 6,000 input tokens for 10 pages, plus a 500-token summary. Page lengths vary; adjust the numbers below.
One run sends your input to the model once and receives an answer. Tokens are pieces of text: input is what you send, output is the answer you receive.

How this estimate works
Estimates exclude taxes, tools, cache storage/writes, free allowances and custom discounts. Image estimates cover output only, not prompt or reference-image charges. Quality modes differ by model. Unlisted settings are not treated as free.
API and provider access
Where to get Grok 4.6
Availability
Regions and access stage
Direct API access runs in published US clusters and the model is also listed through model gateways.
Direct model documentation lists us-east-1 and us-west-2; gateway and account availability varies.
Check live availabilityData and training
The route matters.
SpaceXAI says API inputs and outputs are never used for training without explicit permission. Requests are encrypted and retained for 30 days by default; team-level zero data retention is available with feature tradeoffs.
This is a concise reading of the cited provider material, not legal advice. A third-party gateway can have different storage, routing, training, and residency terms from the model maker's direct API.

How much does Grok 4.6 cost?
$2 input · $6 output / 1M tokens. Price shown for prompts below 200K tokens. SpaceXAI lists higher long-context rates once that threshold is reached.
Where is Grok 4.6 available?
Direct API access runs in published US clusters and the model is also listed through model gateways. Direct model documentation lists us-east-1 and us-west-2; gateway and account availability varies.
Is my Grok 4.6 API data used for training?
SpaceXAI says API inputs and outputs are never used for training without explicit permission. Requests are encrypted and retained for 30 days by default; team-level zero data retention is available with feature tradeoffs. The policy belongs to the provider route and account terms, so verify it again before production use.
Price comparison
One price per model, using the same input/output mix. We weight each API rate by its share of one million total tokens and use the lowest matching reviewed route. This is a comparison rate, not a cost per task or a quality score. Tokenizers, caching, reasoning and long context can change your actual bill.
