> xAI put Grok 4.6 on Microsoft Foundry in public preview at $2 input / $0.50 cached / $6 output per million tokens (Global Standard) — two weeks after the model GA and a week after Amazon and Google cloud ports. Watch: Foundry Learn docs list 200k context against xAI’s 500k card.

**Corrected October 14, 2026:** Sourced Grok 4.6's Foundry price to Microsoft's blog and removed an unverified claim that it matches the xAI API and Bedrock prices.

Grok 4.6 is now on **AWS, Google, and Microsoft** inside two weeks. That is a **procurement** story as much as a model story: enterprises can keep IAM, VPC, and existing cloud commits and still call the new flagship.

**xAI** said **Grok 4.6 is now available via Microsoft Foundry**. **Microsoft**’s Foundry blog (Mahesh Balachandran, same day) calls it **public preview** in the Foundry Models catalog: evaluate against other frontier models, deploy managed endpoints, enterprise governance. Microsoft lists Global Standard pricing of **$2 input / $0.50 cached / $6 output** per million tokens. xAI states **500k** context (Microsoft's catalog lists 200k) and **low / medium / high / xhigh** reasoning. Microsoft Learn later documents `grok-4.6` (preview) as **200k** context, **Global Standard**, Chat Completions + Responses, `model-format "xAI"` — which does not match xAI's 500k figure. **@Azure** posted the catalog link the same afternoon.

## What shipped

| Item | x.ai/news + Microsoft Foundry blog Aug 26 |
|------|-------------------------------------------|
| **Surface** | Microsoft Foundry Models, **public preview** |
| **Price** | **$2 / $0.50 cached / $6** per 1M tokens (Global Standard) |
| **Positioning** | Long-running agents, coding, engineering, office, research |

Grok models were already on Azure/Foundry in older SKUs (`grok-4`, `grok-4.1-fast-reasoning`). This post is **4.6 specifically**.

Same **cloud-distribution** pattern as OpenAI Daybreak-on-Bedrock.

## Limits

- Foundry’s **200k** context in Learn may be a preview cap or a docs lag on xAI’s **500k** card — unresolved here.
- Public preview, not GA on Foundry.
- Microsoft’s “1.5T-scale” framing is partner marketing, not an independent parameter count.
