Scores by test
Methodology →What you need to know
Grok 4.5 is a high-reasoning model optimized for complex logic and structured data generation. It achieves perfect internal scores in strategic analysis, creative problem solving, and tool calling, making it highly effective for agentic workflows and technical tasks. Its 500K context window is fully utilized, scoring 5/5 for long context performance, which allows for the processing of massive datasets without significant loss of faithfulness.
At a blended cost of $5.00 per million tokens, this model is positioned in a premium price tier. While the cost is high, the value is concentrated in its ability to handle structured outputs and tabular data perfectly. However, the model struggles with basic classification and safety calibration, both scoring 2/5, suggesting it may fail at simple labeling tasks or produce unfiltered responses.
Use this model if your application requires complex strategic planning, high-fidelity structured data, or the processing of very large documents. Skip this model if you need a reliable classifier, a strictly moderated safety profile, or a cost-effective solution for simple text processing.
