xAI: Grok 3
Analysis Summary
Grok 3 is xAI's full-size model, with solid GPQA, MMLU Pro, and long-context reasoning scores. Tool use and function calling are supported across a 131K context window, and the instruction-following benchmark is among the stronger results in its tier. However, its intelligence index of 18.4 is lower than Grok 3 Mini's 22.5, which is an unusual inversion.
For businesses, Grok 3 suits general reasoning, content drafting, and code assistance tasks. The long-context reliability (lcr 0.547) is a genuine advantage for document-heavy workflows. That said, the text-only modality limits its versatility compared to multimodal alternatives at similar price points.
At $3.00 input and $15.00 output per million tokens, the cost is difficult to justify when Grok 3 Mini outperforms it on key benchmarks at a fraction of the price. Unless a specific use case demands the full model, Grok 3 Mini is the more rational choice for most business deployments.

Editorial notes
Grok 3 from xAI offers strong reasoning, coding, and long-context performance with tool use and function calling, but its $3/$15 pricing is hard to justify given Grok 3 Mini's superior benchmark scores at a fraction of the cost.
