GLM-5.3 Beats GPT-5.6 and Claude via Post-Training Scaling
togethercompute · x · 2026-08-31
GLM-5.3 has outperformed GPT-5.6 and Claude Fable 5 on agentic benchmarks, with the 5.3 Flash version following closely behind.
Notably, GLM-5.3 achieved this without a new base model. @zaiorg retained the GLM-5.2 base and scaled post-training using more long-horizon environments, diverse tasks, and RL compute.
