We still don't know exactly when the Steam Frame will release, but we're seeing more work towards it arriving in code for SteamOS Manager.
SteamOS Manager was opened sourced by Valve back in May 2025, and for those that don't know of it — it's a system daemon to control various Steam interactions with operating systems including the likes of TDP management, GPU clock management, BIOS updates and more.
The project has a Steam Frame branch on Valve's GitLab instance, with a developer committing code that notes "Initial support for Steam Frame" and inside:
Assumes aarch64 => Steam Frame for now, and Implements a basic devfreq-based GPU clock. More to come.

You might think this is a bit late to only just be adding support since it's supposed to launch sometime soon, but this is only what is public. Valve, like a lot of companies, will have a lot of private code going on. So this is just some of that work going public.
We also had a very recent Proton 11 Beta update that was clearly for the Steam Frame too.
It's all starting to come together now.
