Comprehensive side-by-side LLM comparison
Both models show comparable benchmark performance. Grok 3 offers 868.9K more tokens in context window than Grok 3 mini. Grok 3 mini is $17.20 cheaper per million tokens. Grok 3 supports multimodal inputs. Both models have their strengths depending on your specific coding needs.
xAI
Grok 3, released by xAI in February 2025, is a large language model trained on xAI's Colossus supercluster with substantially increased compute over previous generations. It features a 1M token context window, RL-enhanced Think mode for extended reasoning, and demonstrated strong results on mathematics, coding, and scientific benchmarks. Grok 3 targets complex reasoning, real-time information tasks via X platform integration, and agentic workflows via the xAI API.
xAI
Grok 3 mini, released by xAI alongside Grok 3 in February 2025, is a compact reasoning model from the Grok 3 family featuring RL-enhanced Think mode for extended chain-of-thought processing. It features a 131K token context window and targets STEM tasks, mathematics, and coding applications where cost-efficient reasoning with configurable depth is required.
