Scores by test
Methodology →What you need to know
Qwen3.8 27B distinguishes itself through high-reasoning capabilities and exceptional reliability across complex cognitive tasks. It achieves perfect internal scores in strategic analysis, agentic planning, and creative problem solving, positioning it as a top-tier option for autonomous workflows and high-level architectural planning. Its 1M token context window is backed by a 5/5 long-context score, meaning it maintains coherence and faithfulness even when processing massive datasets.
The model is priced at $0.425 per million input tokens and $2.55 per million output tokens. Given its overall rank of 20th out of 147 models and a high average internal score of 4.69, the blended cost of $2.02/MTok represents a high value-to-performance ratio for developers needing near-frontier intelligence without the cost of the largest proprietary models.
While the model excels in logic and faithfulness, it shows slight relative weakness in execution-heavy tasks. Scores of 4/5 in structured output, tool calling, and constrained rewriting suggest it may require more precise prompting or validation layers when used for strict API integrations or rigid formatting requirements compared to its reasoning performance.
Use this model if your application requires complex agentic planning, deep strategic analysis, or processing of extremely large documents. Skip this model if your primary requirement is flawless, zero-shot structured data extraction or highly rigid constrained rewriting.
