Scores by test
Methodology →What you need to know
Grok 3 Mini differentiates itself through high reliability in execution and consistency. It achieves perfect internal scores for tool calling, persona consistency, and faithfulness, making it a stable choice for applications requiring strict adherence to a specific brand voice or precise API interactions. Its 131K context window is fully utilized, as evidenced by a maximum score in long-context processing.
The model is priced aggressively for its capabilities, with a blended cost of $0.450/MTok. While it ranks lower overall (#55 of 71), this rank is heavily skewed by significant failures in safety calibration and tabular data processing, both scoring 2/5. It is not a general-purpose reasoning engine, as it performs only moderately in agentic planning and strategic analysis.
Developers should use this model for high-volume automation tasks that require reliable tool integration, long-document analysis, or rigid persona maintenance on a budget. Skip this model for data-heavy tasks involving tables, applications requiring strict safety guardrails, or complex multi-step autonomous planning.
