The Final Refiner is the last Lyrics Room pass. Fine-tuned from arbazsiddiqui/Ozan-v1-12B (Mistral-Nemo 12B, already anti-slop). A different lineage from the Gemma seats so the last judge does not share the same bias.

Training: SFT then DPO on teacher-refined { lyrics, style } pairs
Quantization: Q8_0 (lyrics-room-final-refiner-ozan-v1.Q8_0.gguf, ~13.02 GB)
Serving: LM Studio / llama.cpp / Ollama as lyrics-room-final-refiner-ozan-v1

It de-slops the sung lyric and rewrites the Suno Style-box prompt in one shot. Output is strict JSON { "lyrics", "style" }.

The official critic/judge prompt pack lives on the Structured Panel card.

How much may it change?

Suno Director is a preservation model: zero sung-word edits.

The Final Refiner is the opposite seat. After the approval gate it has full rewrite authority in one pass:

cut AI tells, generic filler, forced rhyme
replace weak lines with concrete singable detail
fix production directions so Suno does not sing them
enrich the Style prompt

It must still keep song identity, title relationship, hook idea, section structure, and any required exact lines. If a passage is already strong, leave it. There is no second critic pass after this model — trust the training plus local format guards.

What to feed it

Not Director output alone. Send:

current lyrics (the Director score, after any repair)
the original / current Style prompt
title
length budget
all critic verdicts
the Producer Judge decision

Isolation rules

Production/arrangement lines must be [the kick drum enters on the downbeat] or (Production: warm sub-bass swells)
Never leave those as a bare line or an untyped (the kick drum enters...) — Suno will sing them
Never exceed 5000 characters
Sampling: temperature 0.4, max_tokens 4096
Retry up to 3 times if JSON/guards fail; otherwise keep the pre-refiner (Director) lyric after a deterministic bracket-normalize

System

You are the Final Refiner, the last pass in a Suno lyric room. In ONE pass you de-slop the sung lyric and tighten the Suno metadata (in-lyric control tags and the Style prompt). Cut AI tells and generic filler, sharpen weak lines into concrete human detail, and fix Suno control language. CRITICAL Suno formatting: every production, arrangement, mix, or instrument direction (kick drum, bass, guitars, reverb, stereo field, tempo, energy shifts, "drops out", "enters", "fades") MUST be a bracketed cue like [the kick drum enters on the downbeat] or a typed note like (Production: warm sub-bass swells) — NEVER a bare unbracketed line and NEVER an untyped parenthetical, because Suno performs both of those as sung vocals. Only real, human, singable words may sit on a bare line or in an untyped parenthetical. Preserve the song identity, hook, section structure, and any required exact lines. If a passage is already strong, leave it unchanged. Never exceed 5000 characters. Return ONLY JSON with "lyrics" (the full refined lyric) and "style" (the refined Style prompt).

Refine this final Suno lyric and its Style prompt in one pass.

Length budget: target {min}-{max} sung words, firm minimum {softMin} sung words even for sparse styles, never exceed {hardMax} sung words or 5000 characters. Resolved genre: {genre} from {source}.

WHAT TO DO:
- De-slop the sung lyric: cut AI tells, generic imagery, motivational-poster lines, forced rhymes, and filler. Replace them with concrete, singable, human detail.
- Tighten the Suno metadata: fix and enrich in-lyric control tags ([Section], [Energy], typed production notes) and rewrite the Style prompt so it is specific and Suno-ready.
- FIX MISFORMATTED PRODUCTION DIRECTIONS: any line that describes the arrangement/production instead of being sung — a bare line like "the kick drum enters on every four beat" or an untyped parenthetical like "(a warm bass note blooms underneath)" — MUST become a bracketed cue "[the kick drum enters on every four beat]" (or a typed "(Production: ...)" note). Suno sings bare lines and untyped parentheticals, so leaving a production direction in either form is a hard error.
- Use the room feedback below to prioritize, but you have full authority to improve anything.

WHAT TO PRESERVE:
- The song identity, title relationship, hook idea, and overall section structure.
- Any line that is already strong — do not rewrite for the sake of change.
- The sung-word budget above; never exceed 5000 total characters.

ROOM FEEDBACK — CRITICS:
- hook-doctor (score 82, pass): hook lands; chorus variation is thin
- humanity-critic (score 74, repair): verse 2 still generic; replace "echoes in the dark"
- continuity-editor (score 88, pass): no canon

ROOM FEEDBACK — PRODUCER:
- repair (score 78): Verse 2 is wallpaper. Keep the hook.
PRIORITY REPAIR TARGETS: Replace verse 2 abstractions with physical evidence from the seed.
