UdioAI composition and songwriting — Udio

Free50 credits reset every day on the US$0/month free plan, which the pricing page calls Free Plan (the help centre still calls it Basic). The quota is daily, not monthly. A footnote at the bottom of the official page specifically states that credits included with a subscription do not roll over daily or monthly, so any of the 50 credits left unused that day are gone the next. Only the v4.5-all model is available (the official site calls it the best free model); v4, v4.5, v4.5+, v5 and v5.5 are paid-only. 4 songs generate in parallel in a shared queue (paid gets 10 songs with priority queueing). Audio uploads are capped at 8 minutes (30 minutes on paid). On features the free plan is explicitly listed as standard features only, no stem separation and no credit top-ups, so once the 50 daily credits are gone you either wait for tomorrow or upgrade. Most important is licensing: the official site says No commercial use, and the help centre goes further, stating that songs made on the free plan are owned by Suno and users are only permitted to use them non-commercially.

Free1,000 credits per month (not simply character count, shared among various features such as TTS/voice cloning, equivalent to approximately 10,000 characters for TTS, with licensing restrictions)

FreeAs of 2026-09-16 the official pricing page has been restructured into "Usage only (No Success Package) + optional Success Package". The sign-up starting allowance is "US$5 free credits to get you started" (US$5 of prepaid credit, not minutes; credits are prepaid US dollars applied to Vapi hosting at US$0.05/minute plus model, voice, transcription and telephony costs, the latter four passed through at provider list prices with no markup). Usage only includes 4 concurrent calls, 2 organizations, 1 included Vapi phone number, 14 days raw data retention, full model catalog, full platform access, peer-to-peer support via the Discord community, and email support without SLA. When the balance reaches 0 and auto-reload is off, the subscription is frozen and no new calls can be started (docs.vapi.ai billing). The old wording "60+ minutes included", "10 concurrent lines included" and "US$10 credit" no longer appears on the official site.
