Frontier models evaluated on log(N)-Questions game over Wikipedia
A study evaluates six frontier language models on a two-agent communication task where a questioner identifies a target from N Wikipedia paragraphs using exactly log2(N) yes/no questions. The experiment ran 408 games across document sets of 4 to 1024 paragraphs, revealing significant performance disparities among the tested models.
GLM-5.3 Flash approaches Claude Opus 4.8 on coding benchmarks
Z.ai revealed that the previously anonymously tested model ox-alpha is GLM-5.3-Flash, a 320B-parameter Mixture of Experts (MoE) model with 18B active parameters.
GLM-5.3 matches Claude Fable 5 accuracy on DeepSWE at a fifth of the cost
A comparison of GLM-5.3 and Claude Fable 5 on the DeepSWE benchmark reveals that while both models achieve near-identical first-shot accuracy (69.0% vs 69.7%), GLM-5.3 is significantly more cost-effective and performs better in multi-attempt scenarios.
