crm_expert · reddit · 2026-08-23
Author tested multiple frontier models (Claude Fable 5, GPT 5.6 Sol, Kimi K3, etc.) on a task to extract data from 20-30GB log files. All models except Fable 5 crashed by loading files into memory, whereas Fable 5 successfully streamed the data. Author concludes Fable 5 demonstrates superior basic intelligence over GPT 5.6 Sol.
