Glimpse C1 2B

C1 is the cleanup model in Glimpse. It turns raw dictation into clean text, entirely on your computer.

Filler and false starts. Ums and abandoned restarts disappear.
Self-corrections. "At two, no actually three" becomes "At three."
Punctuation. Sentences come back with the marks in the right places.
Spoken commands. "Make this a bullet point list" makes a list.
Modes. Follows writing instructions, from a formal email to a quick chat message.

C1 is a LoRA adapter on Ternary Bonsai 2 2B from PrismML, a ternary model derived from Qwen3.5. Read the announcement.

Usage

C1 runs in Glimpse on Mac (Metal) and Windows (Vulkan). It was trained on Glimpse's cleanup prompt, with the dictation in the user turn as <transcript>…</transcript>. With other prompts, expect weaker results.

Limitations

It is a 2B model. Long or heavily tangled dictation can come back with a correction missed or a phrase kept that should go.
Modes are followed on about 80% of held-out cases.
It is tuned for cleanup. It is not a chat model.
