xAI veröffentlicht Grok 4.3 mit 1M-Kontext und 40 % Preissenkung

xAI Ships Grok 4.3 With 1M Context and 40% Price Cut

xAI released Grok 4.3 with a 1 million token context window, always-on reasoning, and native video input. Pricing drops approximately 40%: $1.25 per million input tokens, $2.50 per million output tokens (down from Grok 4.20 rates). The model tops leaderboards for agentic tool calling, instruction following, and case-law and corporate-finance benchmarks. Available via the xAI API and OpenRouter immediately.

Why It Matters

At $1.25/M input with a 1M context window, Grok 4.3 sets the most aggressive price-per-context-token point among frontier models, making "feed the full codebase or legal matter" economically default rather than exceptional for cost-sensitive deployments.
