AI in the AM — Week 2 Highlights (June 2026)
"The models up until Fable basically didn't really move the needle on what the small models can do. They basically just couldn't do this post-training effectively. But here we see more than 10x improvement on small models' ability to do these tasks."
Thoughtful AI's testing revealed that Fable achieved over 10X improvement in training small specialist models on complex tasks, while previous frontier models including prior Claude versions essentially failed at effective post-training. This represents a potential breakthrough in automated AI research capabilities and recursive self-improvement, as it demonstrates frontier models can now successfully perform the work of human post-trainers.
