UnoRouter free models
UnoRouter marks part of its catalog free: a model carrying the :free suffix routes only to free providers and never uses an account balance, while the same model name without the suffix is the paid version billed per token. Access requires a UnoRouter account and an API key. UnoRouter's own cap is 1 request per minute, per free model, per user, layered over the upstream provider's own cap, daily token budgets on some free pools that reset at midnight UTC, tokens-per-minute caps triggered by very large prompts, and a per-user concurrency limit on parallel requests. A rate-limited route returns 429 with a Retry-After header, and a model whose free providers are all busy returns 503, which usually clears in minutes. UnoRouter's models, pricing and rate limit pages do not state whether a credit card is required. There is no announced expiry, and availability is best effort: a model leaves the catalog only when every channel is out, and it returns within minutes once a channel recovers.

Models
Free routes carry a :free suffix in UnoRouter's own catalog, and the set changes as free pools drain or upstream providers change. On 2026-09-28 the newest catalog listings included space-bunny-alpha:free, mimo-v2.6-flash:free, mimo-v2.6-pro:free, axon-1.8-pro:free, axon-1.8-flash:free, axon-1.8-lightning:free, atria-dawn-preview:free, ling-3.0-flash-vl:free, nex-n2.5-mini:free and k2-horizon:free. Not all free models support tool calls or vision, so check the capability badges on the model page.
Signup, payment, data
- Signup A UnoRouter account and an API key are required. UnoRouter's documentation does not state which sign-in methods are available or whether a credit card is collected at signup.
- Card / payment Not stated by the provider.
- Training Not stated by the provider.
- Data terms UnoRouter's models, pricing and rate limit pages do not state how prompts sent to free models are handled or whether they can be used for training. Free requests route across upstream provider groups and can fail over between them, so check UnoRouter's privacy policy and the policy of the provider serving the model before sensitive use.
