Grok 4.6 Hits Google’s Agent Garden Two Days After Bedrock
xAI made Grok 4.6 available on Google Enterprise Agent Platform via Model Garden at $2 / $0.50 cached / $6 per million tokens — the same list as Bedrock two days earlier — with a 500k context window and low through xhigh reasoning effort. Google-cloud distribution, not a dual-date of the August 12 model GA.
xAI is now on AWS and Google agent runtimes within a week of 4.6. Google customers can mix Gemini 3.7 Flash (Aug 13) and Grok 4.6 in one garden.
xAI put Grok 4.6 on Google Enterprise Agent Platform through Model Garden (publishers/xai/model-garden/grok-4.6). Price matches Bedrock and the first-party API: $2 input / $0.50 cached / $6 output per million tokens. Context 500k; effort low, medium, high, xhigh. This is Google-cloud distribution, two days after Amazon Bedrock — not a dual-date of the August 12 model GA or the August 19 AWS post.

- Whether Vertex/Agent Platform discounts below $2/$6 is open.
