Grok 4.6 Arrives on Amazon Bedrock, a Week After Launch
On August 19, 2026, SpaceXAI made Grok 4.6 generally available on Amazon Bedrock at the same $2 / $0.50 cached / $6 per million tokens as the first-party API, with a 500k context window and low/medium/high/xhigh reasoning effort, in supported AWS Regions.
TLDR
SpaceXAI on August 19, 2026 put Grok 4.6 on Amazon Bedrock as general availability for developers in supported AWS Regions. Pricing matches the lab API: $2 input / $0.50 cached input / $6 output per million tokens. Context 500k; reasoning effort low, medium, high, xhigh. This is cloud distribution of the August 12 model, the same pattern as OpenAI Daybreak on Bedrock (August 11)—not a dual-date of the model GA.
What shipped
| Item | Detail (x.ai/news primary) |
|---|---|
| Date | August 19, 2026 |

| Model | Grok 4.6 (long-running agents, interactive/visual work) |

Grok models have been on Bedrock since June 17, 2026. This post is 4.6 specifically, one week after the flagship launch.
Product-line de-dupe: not Grok 4.6 launch (Aug 12), not Grok 4.6 in GitHub Copilot (Aug 14), not Grok Build GA the same day.
Why this story matters
Frontier labs now treat Bedrock as a same-week entitlement, not a quarter-lag enterprise port. AWS customers can call Grok 4.6 inside existing IAM, VPC, and procurement without a SpaceXAI contract. Watch: whether Google’s Enterprise Agent Platform (two days later) prices the same $2/$6, or whether clouds start discounting.
