What stands out
01
GLM-5.2 has the top reported result. Its 91.2 GPQA-Diamond score edges the roughly 90 reported for DeepSeek V4 Pro. groundy.com
02
MIT covers half the shortlist. GLM-5, DeepSeek V4 Pro and GLM-5.2 are reported under MIT terms; Qwen 3.5 and Inkling use Apache 2.0.
03
Total size and active size differ sharply. The MoE models activate only 17B–55B parameters per token despite total sizes from 397B to 1.6T.
04
Benchmark comparability is imperfect. Five sources identify GPQA-Diamond; the Qwen 3.5 source reports 88.4 without naming the GPQA variant.

Method: live-web search on 26 Aug 2026; 1,242 unique pages scanned in the broad candidate search, with follow-up checks across additional search results. “More than 30B” means total model parameters, not active parameters per token. Scores reproduce the cited reports and are not normalized across prompting, tools or evaluation settings. “Permissive” includes MIT, Apache 2.0 and the reported OpenMDW-1.1 weights license.
