Only Anthropic's Claude Opus 5 (63) and Claude Fable 5 (62) score higher. That's a five-point jump over its predecessor, Grok 4.5. Grok 4.6 performs especially well on agentic tasks, where models independently carry out multi-step workflows. On the [GDPval-AA v2 benchmark](https://the-decoder.com/openai-says-top-ai-models-are-reaching-expert-territory-on-real-world-knowledge-work/), which aims to measure real-world knowledge work on a computer, it ranks second with an Elo score of 1,753, trailing only Claude Opus 5. It completes complex tasks in about 53 steps. Claude Opus 5 needs roughly 103. Pricing stays at $2/$6 per million tokens. That's more than 60 percent cheaper than Claude Opus 5 ($5/$25) and GPT-5.6 Sol ($5/$30). Grok 4.6 is available now through the [API](https://console.x.ai/), [Cursor](https://cursor.com/), [Grok Build](https://x.ai/build), and partners like OpenRouter, Vercel, and Cloudflare. For the first week, x.ai is offering double the usage quota in Grok Build and Cursor. ``` AI News Without the Hype – Curated by Humans Subscribe to THE DECODER for ad-free reading, a weekly AI newsletter, our exclusive "AI Radar" frontier report six times a year, full archive access, and access to our comment section.
