xAI Releases Grok 4.6 with Top Performance and Same Pricing

xAI officially released Grok 4.6 on August 12. The model achieved leading results on multiple benchmarks while maintaining the same pricing as the previous generation, making it a market focus for its high cost-performance. Musk and NVIDIA officially praised it, and the model is fully integrated into Grok Build, Cursor, Grok Bot, and the xAI API.

Confirmed

• Benchmark performance: Grok 4.6 ranked first on the GDPVal-AA v2 benchmark with an ELO of 1753, surpassing Fable 5 Max and GPT-5.6 Sol Max. It scored 61 on the Artificial Analysis Intelligence Index, tying with GPT-5.6 Sol, behind only Claude Opus 5 and Claude Fable 5. It ranked first in the $5 budget workload test. It scored 94.9% on GPQA Diamond, beating GPT-5.6 and Gemini 3. On the AA-Briefcase agentic knowledge work benchmark, it scored on par with Claude Fable 5 but at one-fifth the cost per task.
• Pricing strategy: Pricing is unchanged from Grok 4.5: $2 per million input tokens, $6 per million output tokens, and $0.50 for cached input. Analyst Gavin SB Baker noted that its performance is comparable to Fable 5 Max but at 85% lower overall cost (80% cheaper input, 88% cheaper output), even cheaper than Anthropic's Sonnet 5.
• Platform integration: Designed for long-horizon agent tasks, it is integrated into Grok Build, Cursor, Grok Bot, and the xAI API. The official announcement said that for one week after release, Cursor and Grok Build users get double token credits.
• Hardware support: NVIDIA officially confirmed that Grok 4.6 is trained and run on the GB300 NVL72 system, leveraging NVLink technology for superior performance and extremely low token cost.

Why it matters

In the current intense competition among large models, Grok 4.6 achieves what Musk hinted at as "Pareto gold." It not only demonstrates frontier intelligence in complex scenarios like real-world tasks and agentic knowledge work, but also dramatically lowers the barrier to top-tier AI models through aggressive pricing. This cost-performance approach directly challenges the market positioning of OpenAI and Anthropic, offering developers and enterprise users a highly cost-effective SOTA option.
