§ Models
Models on Linux
Dettivo for Linux runs whisper.cpp and parakeet.cpp for speech, llama.cpp for Enhanced and meeting analysis, and sherpa-onnx to tell speakers apart. Every model runs on your machine, on a Vulkan GPU or on the CPU.
Who this is for
Anyone picking a speech model, trying Parakeet Ultra, or clearing disk space.
Speech models
First run recommends one of these for your hardware. Meetings transcribe with a Whisper model. The Parakeet models are for dictation.
| Model | Engine | Good for |
|---|---|---|
| large-v3-turbo | whisper.cpp | 99 languages and vocabulary prompts. The default dictation model. |
| small.en | whisper.cpp | English, light enough for a laptop without a GPU. |
| parakeet-v3 | parakeet.cpp | 25 European languages with a time for every word. Fast on a GPU. |
| parakeet-ultra | parakeet.cpp | Moondream's post-train of Parakeet v3. Same languages and size, with a lower word error rate on Moondream's benchmarks. |
| parakeet-v2 | parakeet.cpp | English only. |
Switching to Parakeet Ultra
Terminal
bash
dettivo speech download --provider parakeet --model parakeet-ultra --wait
dettivo speech selection set --provider parakeet --model parakeet-ultraLanguage models
Enhanced and meeting analysis use a Qwen3 model on llama.cpp. dettivo llm download --model <id> --wait fetches one and dettivo config set llm.model <id> selects it.
| Model | For | Size |
|---|---|---|
| qwen3-4b-instruct-2507 | Enhanced and meeting analysis (default) | 2.5 GB |
| qwen3-1.7b | Enhanced, the fast option | 1.1 GB |
| qwen3-4b | Enhanced, the quality option | 2.5 GB |
| qwen3-8b | Meeting analysis | 5.0 GB |
Checked downloads
Every download is checked against a SHA-256 pinned in the catalogue. A file that fails the check goes to quarantine and is never loaded. An interrupted download resumes, and dettivo speech status shows where every model stands.
Models live under ~/.local/share/dettivo/models/. dettivo speech delete --model <id> removes one, and the selected model needs --force.
