Pricing of the Grok 4 Heavy
Grok 4 Heavy, xAI's elite multi-agent reasoning system (2025 release), commands the highest tier API pricing at $30 per million input tokens and $150 per million output tokens through the xAI platform, designed for complex collaborative tasks requiring parallel AI agents. SuperGrok Heavy subscription ($100/month) provides priority access with higher rate limits for production workloads, while batch processing offers 50% discounts ($15/$75 per million); enterprise contracts negotiate 20-40% volume reductions.
This pricing reflects its frontier positioning (1.7T+ parameters, 256K API context), significantly exceeding standard Grok 4 ($15/$75) rates by 2x for PhD-level reasoning across ARC-AGI/Humanity's Last Exam where it achieves state-of-the-art scores. Third-party access via OpenRouter mirrors elevated costs without self-hosting options (proprietary weights).
Leading agentic benchmarks via Colossus-trained multi-agent architecture (100% AIME math, 44.4% HLE), Grok 4 Heavy targets mission-critical 2026 applications despite 10-20x premiums over efficient open models, justified for precision in dense analytical/coding workflows.
Future of the Grok 4 Heavy
Upcoming versions of Grok Heavy will enhance multimodal support, domain-specific customization, and larger reasoning capacity, ensuring it stays ahead as an enterprise AI leader.
