AWS's spec-driven development tool now offers experimental access to xAI's latest model, with a 500K-token context window and tiered credit pricing
Kiro, the agentic development platform built inside Amazon Web Services, now lets paying developers put xAI’s Grok 4.7 to work on their code. The model arrived on November 10, 2026, with an experimental label and a 500K-token context window.
That context window is the feature worth noticing. It lets the model keep a very large chunk of a project in view at once, which matters when the task is untangling a sprawling repository rather than writing one tidy function.
xAI describes Grok 4.7 as its strongest model for coding and knowledge work, designed to stay on track during difficult jobs that can run for hours.
What Kiro users actually get #
Grok 4.7 shows up across all four of Kiro’s surfaces: the IDE, the command-line interface, Crew, and the Web version. Developers can reach it wherever they already work, without switching tools.
Access is limited to four paid plans: Pro, Pro+, Pro Max, and Power. Kiro’s announcement extends support to those tiers only.
According to xAI, the model is built to hold its focus through long, demanding assignments. It is also designed to verify its own output before advancing to the next step.

The pricing is where things get more interesting. Kiro bills Grok 4.7 through a tiered credit structure, and the rate depends on how much of that context window a request uses.
Requests of up to 200K tokens cost 2.7 times the base credit rate. Anything larger is charged at 5.4 times the base rate.
One practical note for existing users: the model does not appear on its own. Developers need to refresh or restart their Kiro client before Grok 4.7 shows up in the model list.
Kiro’s growing model lineup #
Kiro runs as an internal AWS team product, and it takes a deliberately structured approach to AI-assisted coding. Rather than free-form chatting with a bot, developers work from explicit specifications that define what should be built.
The platform first drew public attention in 2025. Since then it has steadily added advanced models from a range of AI developers, and the Grok series now joins that roster.
The timing is notable too. xAI released Grok 4.7 on September 21, 2026, so the model reached Kiro less than two months after its debut.
