andersonbcdefg · x · 2026-07-19
Independent reviewers added Kimi K3 to the prinzbench benchmark. K3 achieved an overall score of 47/99, far surpassing GLM-5.2's 30/99, making it the best open-source model tested to date.
- Overall Comparison: Its score is slightly below February's Gemini 3.1 Pro (50/99), putting them in the same tier. K3 excels slightly in search capabilities but is somewhat weaker in logical reasoning.
- Stability: K3 shows notable volatility; it occasionally misses simpler questions but frequently delivers stunning results on highly difficult ones.
- Core Highlight: With a search sub-score of 11/24, it becomes the first non-OpenAI model to correctly answer more than 10 search questions in this benchmark.
