xAI just made its flagship Grok 4.3 model available on Amazon Bedrock, opening the doors for AWS developers to integrate it directly into their workflows. xAI touts the model as an industry leader in both tool-calling speed and low hallucination rates. It gives cloud builders direct access to Grok inside Amazon's enterprise-grade security stack.
xAI just rolled out Grok 4.3 alongside a new web-based voice cloning suite. The flagship model features permanently active reasoning, a 1-million-token context window, and agentic tool use like web browsing and code execution. API pricing has dropped roughly 40% to 60% compared to Grok 4.2, costing $1.25 per million input tokens and $2.50 per million output tokens.
xAI just rolled out Grok 4.3 Beta to its $300/month SuperGrok Heavy subscribers, adding direct generation of formatted PowerPoint decks, populated spreadsheets with working formulas, and PDFs. Musk clarified the model sits at roughly 0.5 trillion parameters, with a 1T version close to finishing training. Why it matters: Grok is finally expanding from chat and reasoning into hands-on office productivity deliverables.
