Scores by test
Methodology →What you need to know
Qwen3.8 Max is a high-performance frontier model characterized by exceptional reliability in structured tasks and complex reasoning. It achieves perfect internal scores in structured output, tool calling, and strategic analysis, making it a primary candidate for automation pipelines that require strict schema adherence. Its external performance is equally strong, particularly in high-difficulty reasoning, as evidenced by a 99.4% score on AIME 2025 and a 92.7% score on GPQA Diamond.
The model is designed for massive data ingestion, supporting a 1M token context window with a perfect internal score for long-context retrieval. While it maintains a high average quality score of 4.69/5.0, it shows slight relative weaknesses in classification, agentic planning, and constrained rewriting, though these remain strong at 4/5. Its Epoch Capabilities Index of 156.42 places it firmly within the range of top-tier frontier models.
At a blended cost of $5.00 per million tokens, this model is positioned as a premium offering. The pricing is consistent with other high-reasoning frontier models, meaning you are paying for accuracy and context capacity rather than cost-efficiency. It does not offer open weights, requiring a provider-based API integration.
Use this model if your project requires a massive context window, high-precision mathematical reasoning, or reliable tool calling for complex workflows. Skip this model if you are optimizing for low-cost inference or if your primary need is simple text classification.
