How open-source are these glasses really? Are all software components compilable from source, or do they just publish an SDK Espressif-style?

It's all open-source:

Not really, despite the repo being named MentraOS, this repo seems to include only some mobile apps (that either run on a phone or on the glasses), some server code, and some SDKs. Mentra glasses are likely running on a fork of AOSP, which is not in this repo.

AOSP (or even a minimal fork) is way too heavy to be running on the glasses. It looks like the firmware is quite minimal and the "OS" is the app.

Mentra Live runs AOSP similar to the other AI glasses on the market (Ray-Ban, Xiaomi AI Glasses, RayNeo V3 AI Glasses, etc). It's heavy, but allows us to ship fast. You'll find this code in `asg_client` folder.

We're also working on a pair of HUD glasses that will release in 2026 using an NRF5340 MCU. The code for this is being developed in the `mcu_client` folder.

Please have an option for local processing. I would love to be able to use my locally running Gemma 3n model on my phone for low latency and for them to work without internet connectivity.

We're going to be putting out a Mentra Edge SDK in the next few months, but it comes with some downsides. Using your phone as a compute device is a battery hog, and you can only connect one app to the glasses at a time.
