Newly concerning for the AGI optimists...

Uhm Guys… Mythos (Fable) is AGI. On the left is the ACTUAL Lovable Mobile App. On the right is my Lovable version I built with Mythos in 2 prompts. My version SMOKED it.

do you use obsidian for your agents memory vault?

Who’s ready for the 2000$ / month plans?

Even although the company isn't named in this tweet... ...you know exactly who he's talking about, don't you?

If you’re not smart enough to understand frontier LLM research or security vulnerabilities (like me) Fable is absolutely insane, and an absolute pleasure to use.

Claude Fable 5 thinks document parsing is beneath it It is absolutely crushing on all reasoning-intensive/long horizon benchmarks: SWE-Bench Pro, FrontierCode, GDPval, Runescape, etc. But for document understanding tasks, it is roughly equivalent with Gemini 3 Flash in performance, at roughly 10-15x the token cost. We benchmarked the model on ParseBench and compared it against all other frontier models. It is definitely up there compared to other frontier models, but falls far short of specialized OCR providers. What we found interesting is that Fable 5 is self-aware about this. When we ask the model what tasks it enjoys the last, it actively said that it dislikes tasks "where the request is fully specified and the answer is fully known" - implying part of it being bad is due to laziness and lack of willingness to actually solve the task at hand.
