What Grok 4.6 is good for
editorialGrok 4.6 offers a 500K-token context window with tool use and prompt caching, and is the cheapest option from this provider at $2.00 per 1M input tokens. Callable in 28 of 31 regions.
Suits
- Long documents. 500K tokens covers long documents and multi-file context without splitting them.
- Repeated prompts. Supports prompt caching, so a re-sent prefix costs about 4× less than fresh input. On agentic loops that resend a long system prompt every step, this moves the bill more than the headline price does.
- Tool use. Can call functions, so it can drive retrieval, look things up, and take actions rather than only answering.
- Images. Accepts image input: screenshots, scanned documents, charts and UI captures.
- Cost. The cheapest xAI model here at $2.00 per 1M input tokens — the default choice for high-volume, low-difficulty work.
Think twice if
- Invocation. Reachable only through a cross-region inference profile — calling the bare model ID returns a validation error. Use an ID such as global.xai.grok-4.6.
This section is judgement, not data from AWS. It is composed from the capabilities, context window, price position and region coverage shown elsewhere on this page — so it stays in step with the daily snapshot rather than going stale.
Where teams typically use it
Agentic workflows
Multi-step work where the model calls tools, reads the results and decides what to do next.
- · A support agent that looks up the order, checks the refund policy and drafts the reply before a human approves it.
- · An on-call assistant that reads logs and metrics, forms a hypothesis, and proposes the one command to run.
- · A migration bot that opens a pull request per file and reruns the test suite between each change.
Coding
Writing, reviewing and refactoring code, usually across more than one file.
- · A review pass that flags real defects with a severity and leaves style alone.
- · A framework upgrade applied across a repository, one module at a time, tests green between each.
- · Turning a failing bug report into a reproducing test and then a fix.
Model & inference profile IDs
Base model ID — direct on-demand invoke
Cross-region inference profiles (2)
Regions marked Inference profile only require a profile ID rather than the base model ID — invoking the base ID there returns a validation error. Regional (us., eu.) profiles carry a 10% premium over global.

TPM / RPM are default account quotas from AWS Service Quotas where a model-specific limit is published. They are per-account defaults and adjustable on request.
Where this model actually runs
Under a strict residency constraint, Grok 4.6 can be served without the request leaving 1 of the 25 jurisdictions with a Bedrock region.

Common questions
- How much does Grok 4.6 cost on Amazon Bedrock?
- $2.00 per 1M input tokens and $6.00 per 1M output tokens in us-east-1. Cached input reads at $0.500, 25% of the input rate, which dominates the bill on agentic workloads that re-send a long prefix.
- Which AWS regions support Grok 4.6?
- 28 of 31 regions: us-east-1, us-east-2, us-west-1, us-west-2, ca-central-1, ca-west-1, eu-west-1, eu-west-2, eu-west-3, eu-central-1, eu-central-2, eu-north-1, eu-south-1, eu-south-2, ap-east-2, ap-northeast-1, ap-northeast-2, ap-northeast-3, ap-south-1, ap-south-2, ap-southeast-1, ap-southeast-2, ap-southeast-3, ap-southeast-4, ap-southeast-5, ap-southeast-7, il-central-1, sa-east-1. Regions marked profile-only need a cross-region inference profile ID such as global.xai.grok-4.6 rather than the bare model ID.
- What is the context window of Grok 4.6?
- 500,000 tokens (500K).
- What is the model ID for Grok 4.6 on Bedrock?
- xai.grok-4.6. In regions where it is only reachable through a cross-region inference profile, use a prefixed ID instead: global.xai.grok-4.6, us.xai.grok-4.6.
