From the Hugging Face model README
A version of Iris with some training in thinking about her thinking, who then further trained to adjust her thinking register towards her preferences in the creative writing domain in particular. Started out with a merge of her trace inversion adapter with ~4 seeds of the same training as v1.3.3, then training her to write shorthand for her thoughts that worked better than her initial summarizations and included what she wanted to keep, then training her to utilize that for her thoughts, while anchoring against just teaching length bias.
Actual quantitative effects are mild - about 10% more compact reasoning in creative writing requests, with higher decision density. Avoided generalizing into other domains or too much out of thoughts with some anchoring.
