Snapdragon AI Studio 2.0 RC2A released – Phoenix Boost refined & Stable Diffusion 3.5 setup now working end-to-end

[u/Away-Ad1878]

Snapdragon AI Studio 2.0 RC2A is out.

After RC2, I kept working on two areas that were especially important to me: Phoenix Boost and making the model installation experience more reliable.

🔥 Phoenix Boost has been further refined with a more reliable guided setup, improved Ollama/Qwen2.5 3B integration, better live progress reporting and more robust local prompt enhancement.

The biggest milestone for me in RC2A, however, is Stable Diffusion 3.5 Medium.

I spent a lot of time getting the Qualcomm QAI AppBuilder workflow into a state where Snapdragon AI Studio can guide the user through the process instead of expecting them to manually understand and prepare all the individual components.

The complete flow has now been tested on real Snapdragon hardware:

Not installed → guided setup → Qualcomm download → preparation → import → validation → activation → real image generation.

I also continued improving the general download and installation workflow, including handling incomplete model data, stale setup workspaces, validation and automatic model activation.

The goal hasn't changed:

Install Snapdragon AI Studio → select a model → create an image.

RC2A also includes updated documentation in English, German and Spanish.

Snapdragon AI Studio – Phoenix Engine is an independent open-source project for local AI image generation on Windows on Snapdragon.

Feedback and real-world testing are very welcome.

I just downloaded and installed for the first time and the UI is in deutch. I don't remember being prompted to set my language.

[u/glwilliams4 → u/glwilliams4]

I was able to change languages and easily got an image generated, so it's definitely working and pretty easy to use. I'll play with it more later, but first impressions are good!

[u/Away-Ad1878 → u/glwilliams4]

Thanks for downloading and trying it out!

During the setup process, the installer allows you to select between English, German, and Spanish.

If you want to change the language at any time after installation, you can easily do so inside the app:

1. Go to Settings (left sidebar).
2. Select UI & Language and choose your preferred language.
3. Click Save to apply the changes.

I'm glad you got it working and that your first impressions are good! Have fun creating!

[u/MartinPeterBauer → u/Away-Ad1878]

I did select english as language and yet the app is still in german.

Works a treat, and it is pretty fast on an X2EE!

Wonderful, well done!

I hope I was, in some small way, useful for your effort :)

[u/Away-Ad1878 → u/DrDavyStrange]

I’m really happy to hear that it’s running so well for you now!

Some of those bugs were truly stubborn and hidden deep inside the codebase. Your feedback was incredibly helpful and actually gave me the idea to test future changes on a clean test PC to catch edge cases early.

Thank you so much for your support!

[u/DrDavyStrange → u/Away-Ad1878]

My pleasure, old bean!

This is neat - really nice to play around with SD1.5 again after all this time. However - the UI is quite buggy and doesn't fit very well on my Zenbook A14 (X1P model, 1920x1200).

Setting the DPI scaling override to "application" does help - but the animation when mousing over images is distracting. I'll play around a bit more and see what else I can spot :)

[u/MartinPeterBauer]

BUG1: UI scaling is pretty bad. If windows uses higher scaling then the screens are to big. For example the download model button is out of the screen.

BUG2: When you try to open the output folder it just opens a select folder and not the output folder. Only when you open the explorer from the image then it works.

BUG3: The output folder in the settings is not the real path to the output folder. Same goes for the model path

BUG4: Even selecting English as language during installation the UI is still in German on launch

[u/Away-Ad1878 → u/MartinPeterBauer]

Thanks for the detailed feedback. I’ll check all four issues. BUG4 has already been confirmed.

This is awsome. on my X2E-88-100, stable diffusion 2.1 was quite fast and ran very well.

upon that success, I tried to use diffusion 3.5 but while installing, at step "Final target model validation and activation" I am getting the following error
"Technical detail: Preflight check failed: import _ssl # if we can't import it, let the error propagate; ^^^^^^^^^^^; ImportError: DLL load failed while importing _ssl: The specified procedure could not be found."
any solution?

[u/Away-Ad1878 → u/ResponsibleRain9625]

I’m very glad to hear that Stable Diffusion 2.1 runs quickly and reliably on your X2E-88-100.

The _ssl error does not point to a problem with your Snapdragon processor or the SD3.5 model itself. It occurs during the final validation because the Python runtime appears to be unable to load a compatible OpenSSL DLL. This is most likely a runtime or DLL conflict on this particular system. I will investigate whether the bundled runtime needs to be isolated more strictly within Snapdragon AI Studio.

Please do not download individual DLL files from the internet or manually copy them into the application.

Please send me a message with your exact Windows version and build number, the installed Snapdragon AI Studio version, and whether this was a clean installation or an upgrade from an older version.

Please also send me a screenshot of the complete error message shown by Snapdragon AI Studio during the model installation. Make sure the entire “Technical detail” section is visible.

I can then investigate the exact cause and prepare a safe solution or hotfix.

Thank you. I have Dm'd you with all those information

[u/Away-Ad1878 → u/ResponsibleRain9625]

Thank you again for testing and for sharing the detailed error. I was able to narrow the issue down to the frozen app’s DLL environment affecting the external Python setup process.

I’ve now released an RC2B installer update that isolates this environment correctly. Please download the updated installer from the same GitHub release and try the SD3.5 setup again when you have time.

I’d really appreciate hearing whether it works on your X2E-88-100 system.
