Synthesized from gap research (as of early 2026 claims in that brief — re-verify before relying on dates/rulings).
- Prefer human-authored CC0 / clear commercial licenses for default recommendations.
- Label AI tooling clearly (
tags: [ai-generated]orcompliance:ai-disclosure) when an entry is primarily generative. - Do not treat “public domain because AI” as a shipping strategy — platform rules (Steam disclosure), training-data risk, and publicity/voice rights still apply.
- Exclude free-tier cloud TTS/voice that is non-commercial (ElevenLabs-class) from “commercial OK” lists.
- Prefer local permissive models (Apache 2.0 / MIT) when synthetic VO is needed.
- Steam: research notes player-facing generative assets may require store disclosure; internal coding assistants may not. Check current Valve guidelines.
- US copyright: research cites human-authorship requirements for registration; pure machine output may be unprotected — that does not clear third-party training-data or likeness claims.
- Voice/likeness: generating a real performer’s voice without rights is high risk regardless of model license.
3DTexel ships a human-authored CC0 decal library on the same site as paid premium files and AI generators. The catalog entry is the human CC0 set only. Footer (2026-08-29): free assets CC0; premium and AI assets use a separate 3DTexel License. Do not treat generator output as that CC0 grant.
