Scores by test
Methodology →What you need to know
Kimi K2.6 is a high-performance model optimized for complex reasoning and long-form data processing. Its primary differentiator is a near-perfect internal score across most technical domains, particularly in agentic planning, faithfulness, and structured output. With a 262K context window and a 5/5 score in long context handling, it is built for deep analysis of extensive datasets without losing coherence.
The model's pricing is competitive for its rank, with a blended cost of $2.81/MTok. Given its #5 overall ranking out of 71 models, the cost-to-performance ratio is high, providing frontier-level capabilities in strategic analysis and multilingual tasks at a mid-tier price point.
Despite its overall strength, the model has a significant deficiency in classification, scoring only 2/5. It also shows slight regressions in tool calling and constrained rewriting compared to its other capabilities. This indicates a model that excels at generative reasoning and synthesis but struggles with rigid categorization tasks.
Use this model for agentic workflows, complex strategic planning, and processing large documents where faithfulness is critical. Skip this model if your primary use case is high-accuracy text classification or strict categorical labeling.
