Today we are launching Model Council, a multi-model research feature that brings several models together for one answer.
A taxonomy for next-generation reasoning models
Where we've been and where we're going with RLVR.

Arcee AI | Arcee AI and mergekit unite
Several months ago, I stumbled upon an innovative technique in the world of language model training known as Model Merging. This SOTA approach involves the fusion of two or more LLMs into a singular, cohesive model, presenting a novel and experimental method for creating sophisticated models at a fraction of

whoa so @thinkymachines is doing model merging + customized RLquite a come-up for merging in the past couple weeks, with @arcee_ai mergekit also featuring heavily in AFM. credit due to @jeremyphoward for being the first to make me take modelmerging seriously pic.twitter.com/DtXjX8li4t— swyx (@swyx) June 24, 2025
