A user conducted a test comparing several frontier AI models, including GPT 5.6 "Sol", Kimi k3, GLM 5.3, Qwen 3.8 Max, DS v4 Pro, Grok 4.6, and Claude Fable-5. The test involved processing large log files (20-30 GBs) to extract specific data. All models except Claude Fable-5 failed the task by attempting to load the entire files into memory, causing system crashes. Claude Fable-5 successfully completed the task by implementing a streaming script, demonstrating superior intelligence and efficiency compared to the other models, including GPT 5.6 "Sol". AI

I tested every frontier model from every AI lab - Claude Fable 5, GPT 5.6 Sol, Kimi K3, GLM 5.3, Qwen 3.8 Max, DS v4 Pro, Grok 4.6 and just 1 made it through.

<div class="md"><p>The task as well as the prompt was simple. I did not ask them to make me an OS or a complete game. I just wanted to test their intelligence on something very basic. I have a repo with very large log files, 20-30 GBs each. My working directory <a …
