Is Suno 4.5 free?
No—not for new generations through Suno’s currently documented model lineup. Suno says it is retiring its previous models as v6 rolls out; its current model documentation describes the v6 family, and its v4.5 help-center section is archived. The official materials reviewed do not document a plan or account exception that restores v4.5 generation. [1][2][3]
That is different from saying Suno has no free plan. Suno’s help center says the Free plan receives up to 50 credits daily, replenished once a day using UTC. Its current model documentation identifies v6-mini as available to all users, while v6 and v6-wild are for Pro and Premier subscribers. Those free credits do not establish access to retired v4.5. [3][4]
Budget takeaway: If you specifically need v4.5, don’t pay for a Suno plan on the assumption that it will unlock the model. The current official materials reviewed do not show v4.5 as available for new generation. If a current Suno model will work instead, check the Free plan first; paid plans start at $10 per month, but that is a general starting price, not a price for v4.5 access. [3][5]
Production API: legacy access and budget
Suno’s official MCP Beta is a separate integration route: Suno says it works with Free plans and uses credits from the user’s plan. That does not establish a production REST API for v4.5. [6]
A third-party API documentation site documents a generation endpoint and lists V4_5 and V4_5ALL as separate legacy model identifiers. Its generation documentation marks both as deprecated, says deprecated values remain for backward compatibility, and recommends a V6-series model for new integrations. This documents a legacy compatibility path; it does not establish that a new customer can use V4_5, guarantee continued access, or make V4_5ALL interchangeable with V4_5. [7]
I could not verify a public price, billing unit, or new-customer access condition for that provider’s exact V4_5 identifier. There is therefore no supported per-generation or monthly API budget to quote for v4.5 from the material reviewed. TokenForgeCloud’s supplied public description lists other model families, not Suno; it does not establish a TokenForgeCloud v4.5 offering. [8]
Which route should you choose?
- Casual creation: Try Suno’s Free plan if its current model lineup meets your needs. The daily credits are a general allowance, not v4.5 access.
- You specifically need v4.5 on Suno: Current official materials treat v4.5 as legacy, and do not document a plan that enables new v4.5 generations.
- You need production integration: Treat third-party
V4_5backward compatibility as a provider-specific legacy route, not a guaranteed new integration. Confirm account eligibility, availability, and billing with that provider before building against it.
Bottom line: Suno offers free daily credits, but its current official materials do not offer v4.5 for new generations. A third-party API document retains a deprecated V4_5 identifier for backward compatibility, but its new-customer availability and price are not established here.
