Flowbee Cut — technical dictation cleaner

Fine-tune of Qwen3-4B-Instruct-2507 that cleans raw speech-to-text transcripts for Flowbee, a local-first macOS dictation utility. It removes fillers and stutters, resolves self-corrections, and writes technical speech in its correct form:

This is not a chat model. It was trained to do exactly one thing under one system prompt, and it will clean — never answer — instruction-shaped transcripts ("write a unit test for the auth module" comes back as cleaned text, not a unit test).

Usage contract

The model expects the exact Flowbee Cut system prompt it was trained with (the coder prompt in scripts/cut-eval/prompts.mjs of the Flowbee repo), with the raw transcript as the sole user message, temperature 0. Behavior under other prompts is untested. Serve with llama.cpp:

llama-server -m flowbee-cut-<version>.Q4_K_M.gguf -ngl 99 -c 4096

Training

• LoRA (r=16, attention projections, completion-only loss) on ~4,400 synthetic pairs of messy spoken transcript → clean text: instruction-shaped technical dictation, CLI commands and flags, spoken identifiers and case directives, glossary-conditioned phonetic repairs, everyday dictation, and passthrough negatives. Adapter merged into the base weights, quantized to Q4_K_M.

Files

• flowbee-cut-<version>.Q4_K_M.gguf — versioned releases (~2.5 GB).
• latest.json — machine-read manifest (version, file, sha256, eval score). The Flowbee app checks it on startup and downloads new releases, verifying the sha256 before the file touches a GGUF parser. Do not rename or delete these files by hand.

Limitations

• English only. Training data is English; the base model is multilingual but this fine-tune's behavior on non-English transcripts is untested.
• Tuned for software-engineering vocabulary; exotic garbled jargon without a glossary hint is passed through verbatim by design (never deleted, never guessed).
• Trained on synthetic data seeded with real dictation failures; expect occasional misses on unusual phrasing (e.g. a garbled term directly adjacent to a modifier).
