Grok API
Grok API provides access to xAI's frontier large language models for advanced reasoning, coding, and knowledge work, with real-time information access.
The Grok API offers access to xAI's latest frontier model, Grok 4.6, released on August 12, 2026. This model is designed for long-running agents, complex coding tasks, and in-depth knowledge work, supporting text and image inputs with text-only output. It features a 500K-token context window and enhanced capabilities for multi-step tasks, codebase analysis, and application development.
Grok API offers competitive pricing with significant free credits ($175/month) and advanced models like Grok 4.3 with 1M token context windows. However, it's positioned as mid-tier in a crowded API market and the low Trustpilot rating (1.7/5) suggests user experience challenges that limit its appeal.
