Orion 3 is here. The biggest change is the one you see every time you open the app: a redesigned space for talking, thinking, writing, and exploring. The interface is darker, the controls feel lighter, and the conversation takes center stage.
There is a new foundation underneath it, too. Orion now uses a Qwen 3.5-based model, replacing the Dolphin 3 model based on Llama that powered the earlier releases. The core promise remains the same: your conversations run privately, on your device.
V2 → V3: see the redesign
V2 brought Orion Agent and AI Roleplay into the app. V3 refines how those experiences look and feel, with a near-black canvas, translucent input controls, and a quieter use of accent color.
These are real screenshots from each version, with different conversations and selected themes. Compare the layout and controls; the blue-to-purple change is a theme choice. Select a screenshot to view it at full size.

A clearer visual identity
The crescent now has a brighter lavender-purple identity across Orion’s icon, website, sidebar, and widgets. Loading dots share that same color, giving the app a recognizable signature even when you choose a different conversation theme.
From Dolphin to Qwen 3.5
Earlier Orion releases used Dolphin 3, based on Llama. V3 moves to Qwen 3.5; the current app bundles a compact, quantized 4B model, meaning a four-billion-parameter model stored in a form that uses less memory. It runs locally through the app’s existing inference engine.
That gives us a new base for Orion’s conversations and reasoning experiences while keeping personal prompts and responses on-device. Chat, Agent, Roleplay, and Intelligent Notes remain the places where that model becomes something useful.
The next chapter is already underway
V3 brings the new interface and Qwen-based foundation together. For V4, we are working on our own GPT-style foundation models, pretrained from scratch. Read the V4 research note for the direction we are taking.
