The receipts

Every claim, traceable to a public artifact.

Most AI tools ask you to trust the marketing copy. SongForgeAI publishes the rubric, the model card, the reference corpus, the RFCs, the incidents, the engineering report, and the operating principles. Eight artifacts. Every one of them under CC BY 4.0 or source-controlled in a public git repository. This page is the index.

01

The rubric is published.

"We score against a 12-metric rubric." Most AI tools say something like this. We publish ours under CC BY 4.0, with version, date, and complete metric definitions.

Lyric Scoring Standard v1.1.0
02

The model is named.

"AI-powered." We name the exact model id, the exact temperature, and the exact prompt files. The model card lists known limitations including the bias we cannot eliminate.

Model Card
03

The corpus is open.

"Calibrated scoring." Calibration without exemplars is unverifiable. We publish 12 hand-scored reference entries with composite + per-tier breakdowns, F-band and S-band anchors, and full rationale per entry.

Reference Corpus v0.1.0
04

Every score carries a seal.

"Reproducible." Every API response includes rubricVersion + model id + temperature + buildSha + build number. A third party can pin which deploy emitted any given score.

05

Major changes ship after public RFC.

"Iterative." Most products iterate in private. Major changes to the rubric, scoring pipeline, public API, or pricing open as RFCs at /rfc with a 7-day public comment window.

Public RFC process
06

When something breaks, you read about it.

"Reliable." We publish a postmortem within the same week of every user-visible incident. Plainly worded. Root cause, detection, mitigation, prevention. No corporate fog.

Incidents + postmortems
07

Engineering activity is auditable.

"Active development." A live 14-day engineering report at /engineering is auto-generated from git history. Highlights, CI ratchets, file-touch heatmap, every commit linked to its GitHub SHA.

Engineering report (auto-generated)
08

How decisions get made is documented.

"Principled." 10 operating principles, each paired with the inversion we reject, plus 4 decision gates that translate the principles into operational rules.

Operating principles

What this page is, and isn’t.

This is not a marketing landing page. Every link goes to a public artifact — usually a CC BY 4.0–licensed document or an API response with a verifiable seal. If a competitor matches every one of these, we lose our differentiation, and that’s the right outcome — the category becomes more legible.

Until then, this page exists so you don’t have to take our word for any of it.
