SpaceXAI releases Grok 4.7, which it says is better at verifying its own work and managing longer context, available for $2/1M input and $6/1M output tokens (xAI)

xAI’s Grok 4.7 aims to improve the economics and reliability of enterprise AI by delivering stronger self-verification, longer-context handling, and faster performance at roughly half the cost of comparable models. For CIOs and technology leaders, this could translate into lower AI operating costs, better outcomes for coding and knowledge-work use cases, and increased pressure to re-evaluate current model vendors, workloads, and governance controls as adoption expands across IT and business teams.
