Scores by test
Methodology →What you need to know
Seed 1.6 is a high-precision model optimized for complex logic and structured data. It achieves perfect 5/5 scores in strategic analysis, faithfulness, agentic planning, and tabular data handling. These metrics indicate a strong suitability for enterprise automation and data extraction tasks where accuracy and adherence to strict formats are non-negotiable.
The model offers a massive 262K context window and maintains a 5/5 score for long-context performance, making it an efficient choice for processing extensive documentation. At a blended cost of $1.56/MTok, it is priced competitively for its capability level, providing high-tier reasoning and multilingual support without the premium cost of the top-ten ranked models.
Developers should be aware of a critical failure in safety calibration, which scored 1/5. This suggests the model lacks robust internal guardrails and may produce unfiltered or unsafe content. Additionally, its performance drops in constrained rewriting, indicating it struggles with strict character or word-count limitations.
Use this model if you need a cost-effective, high-context engine for structured data extraction, agentic workflows, or strategic analysis. Skip this model if your application requires strict safety filtering or precise constrained rewriting.
