This document provides an update on the Society Publishers Accelerating Open Access and Plan S (SPA-OPS) project. It discusses the project's interviews with publishers and library consortia. Key findings include that 91% of consortia agree to work with learned society publishers on new models, and 53.85% of consortia would likely participate in initiatives redirecting subscription funds to open access. The document also outlines several transformative agreement models and shows how the Max Planck Institutes rapidly increased open access by negotiating agreements with their top 20 publishers. Next steps include developing a transformative agreement toolkit and quantifying unfunded researchers.
