xAI changelog·high signal
xAI announced on August 19 that Grok 4.6 is generally available on Amazon Bedrock across supported AWS regions, priced at $2 per million input tokens and $6 per million output. It carries a 500,000-token context window and four configurable reasoning levels (low, medium, high, xhigh), positioned for long-running agents and visual work. The pricing undercuts frontier Claude and GPT tiers on Bedrock, which matters if you are routing agent traffic by cost.
