Grok 4.6 arrives, topping GPT-5.6 Sol and Fable 5 Max on agent benchmarks at $2 per million tokens
SpaceXAI has released Grok 4.6, which official benchmarks show beating GPT-5.6 Sol and Fable 5 Max on GDPVal-AA v2 and other agentic tests while priced at just $2 per million input tokens and $6 per million output tokens. The model is live in Grok Build, Cursor, Grok Bot and the API — with OpenRouter, Vercel and Cloudflare also carrying it — and is tuned for long-horizon agent tasks.
