+
+ℹ️ WebGPU fitness for ML frameworks #66 - @jasonmayes @Kangz @grorg
+- ❓ Does WebGPU expose the right API surface to support ML frameworks interactions with GPUs?
+- ✔️ Proposal: New WebGPU extensions for subgroups, cooperative matrix multiply.
+
+ℹ️ Applicability to non-browser JS environments #62 - @jasonmayes @phoddie @huningxin @WenheLI
+- ❓ Pay attention to the applicability of the browser-targeted work to non-browser JS environments, in particular Node.js.
+- ✔️ Proposal: Extend W3C coordination to TC53 and non-browser projects.
+
+ℹ️ Protecting ML models #67 - @jasonmayes @tidoust @pyu10055 @jbingham
+- ❓ Some ML providers need to ensure their ML models cannot be extracted from a browser app.
+- ✔️ Proposal: Investigate existing access control mechanisms for video, learnings from 3D assets.
+
+ℹ️ Support for Float16 in JS & Wasm environments #64 - @cynthia @jasonmayes
+- ❓ Lack of support for float16 in JS and Wasm environments problematic for quantized models.
+- ✔️ Proposal: TBD
+
+ℹ️ In-browser training #82 and Training across devices #83 - @irealva @cynthia
+- ❓ The current in-browser efforts are focused on inference rather than training.
+- ✔️ Proposal: Understand successful real-world usages (e.g. Teachable Machine) and target transfer learning as the initial training use case for related browser API work.
+
+ℹ️ Permission model for Machine Learning APIs #72 - @cynthia @dontcallmedom @anssiko
+- ❓ How to design a forward-looking permission model for ML APIs?
+- ✔️ Proposal: TBD
