xAI has launched Grok 4.3, a significant update to its reasoning model that offers enhanced capabilities at a dramatically reduced price, officially available via API on April 30, 2026. The new pricing is set at $1.25 per million input tokens and $2.50 per million output tokens, which represents a roughly 40% and 60% decrease from its predecessor, Grok 4.20. Notably, Grok 4.3 supports native video input for files up to five minutes long and can generate downloadable PDFs, PowerPoint presentations, and Excel spreadsheets, making it a versatile tool for various applications. It scores 53 on the Artificial Analysis Intelligence Index, positioning it competitively among AI models, while its 1 million-token context window facilitates long-document analysis and complex workflows. This release is crucial for the AI/ML community as it lowers the barrier to entry for developers and users seeking powerful AI capabilities without the high costs associated with other leading models like GPT-5.5 or Claude Opus 4.7. The ability to integrate video and generate Office files enhances usability across fields such as education, security, and business, streamlining workflows significantly. As Grok 4.3 starts rolling out to consumer subscription tiers, it is set to position itself as an essential, cost-effective option for users in need of advanced AI functionalities without exorbitant fees.
