TL;DR: OmniRoute registers 329 providers, with 155 catalog entries marked free/no-auth. The stricter audited budget currently covers 43 recurring pools / 522 model budget entries. Connect several suitable providers for broader fallback capacity; every quota, approval rule, privacy policy, and paid-overage condition still applies.
Many AI providers offer some form of free access. Depending on the provider, that may mean a no-auth endpoint, recurring quota, rate-limited uncapped access, a signup grant, manual approval, or a temporary promotion. Some options require an account, API key, credit card, KYC, or acceptance of provider-specific terms.
OmniRoute aggregates these free tiers into one endpoint. Instead of signing up for 10 different services, you connect them all to OmniRoute and use model: "auto" to automatically pick the best free option for each request.
These providers have a recurring, keyless, or uncapped free-access path in the audited catalog. “Uncapped” means no published token cap; rate, concurrency, account, regional, and policy limits can still apply:
| Provider | Models | Quota | How to Connect |
|---|---|---|---|
| Kiro AI | Claude Sonnet 4.5, Haiku 4.5, DeepSeek V3.2, and others | Audited catalog estimates a 25K-token shared monthly pool | OAuth/account flow; ToS flagged avoid in the catalog |
| OpenCode Free | Current *-free model set in the provider registry | Keyless; no published token cap | No provider credential; ToS flagged avoid |
| Pollinations | Current keyless model set; some former models are discontinued or key-required | Keyless; no published token cap | No provider credential for the keyless models |
| Cloudflare AI | Workers AI catalog | Audited pool estimates ~30M tokens/month from published usage units | Cloudflare account and API credentials |
| Gemini | Gemini Flash family | Audited pool estimates ~60M tokens/month | Google AI Studio API key; rate limits apply |
| Groq | Llama, GPT-OSS, and Qwen models | Audited pool estimates ~15M tokens/month | Groq API key; rate limits apply |
| Cerebras | GLM 4.7 and GPT-OSS 120B | Audited pool estimates ~30M tokens/month | Cerebras API key; rate limits apply |
These providers give you free credits when you sign up:
| Provider | Free Credits | Models | How to Get |
|---|---|---|---|
| DeepSeek | 5M free tokens | DeepSeek V4 | Sign up at platform.deepseek.com |
| LongCat | 10M-token one-time grant | LongCat 2.0 | API key + KYC; pay-as-you-go after the grant |
| Together | $25 signup credit represented as ~25M tokens in the budget model | Provider catalog | Sign up and verify current terms |
| Vertex AI | $300 signup credit represented as ~300M tokens in the budget model | Gemini and partner models | Google Cloud account; billing and eligibility rules apply |
These providers have free tiers with specific limits:
| Provider | Free Limit | Models | Best For |
|---|---|---|---|
| GitHub Models | Audited shared pool estimates ~18M tokens/month | Broad model evaluation | |
| Hugging Face | Small recurring monthly pool | Experiments and model variety | |
| OpenRouter free models | Shared request-limited pool; optional one-time top-up increases the recurring allowance | Broad fallback catalog | |
| AI Horde | Keyless community capacity; availability varies | Opportunistic distributed inference |
The magic of OmniRoute is stacking free tiers. Instead of relying on one provider, you connect multiple free providers and let OmniRoute automatically pick the best one for each request.
Connect several providers to reduce dependence on any single quota:
Then use model: "auto" and OmniRoute will:
Result: broader free-tier coverage with automatic fallback — not a guarantee of unlimited capacity.

Click Providers in the sidebar.
Click the + Add Provider button.
Browse the catalog and inspect each provider's current hasFree, auth, quota, privacy,
and ToS metadata. The provider card and the
Free Tiers Reference distinguish recurring pools,
uncapped/keyless access, signup credits, discontinued entries, and higher-risk sources.
For a NOAUTH provider, no credential is required. OAuth and API-key providers must be
connected through their documented account flow.
Connect several providers whose terms and privacy model fit your use case.
NOAUTH means OmniRoute does not ask you for a provider credential; it does not
guarantee uptime, privacy, or unlimited capacity.hasFree is discovery metadata. It can represent a recurring quota, keyless access,
signup credit, approval program, or promotion.recurring-uncapped means no published token ceiling was available; rate and
concurrency limits still apply.one-time-initial does not recur after the signup grant is consumed.tos: avoid is a warning to review provider terms and account risk before use.discontinued remain historical evidence and must not be presented as
currently free.If one free provider is busy or down, OmniRoute automatically tries the next one. You don't need to do anything.
OmniRoute picks the best free provider for each request based on:
OmniRoute's compression pipeline can reduce eligible prompt and tool-output tokens. The actual savings depend on content, selected engines, provider accounting, and fidelity settings; compression does not multiply every provider quota by a fixed amount.
If provider terms permit multiple accounts or credentials, OmniRoute can treat each connection as a separate routing candidate. Do not create extra accounts to evade a provider's quota or access policy.
The live, pool-deduplicated catalog currently reports:
| Metric | Current audited value | Interpretation |
|---|---|---|
| Recurring quantified grant | ~1.53B tokens/month | Shared pools counted once; excludes uncapped providers from the sum |
| First month with signup grants | ~2.15B tokens | Recurring total plus one-time and recurring credits |
| Quantified inventory | 43 pools / 522 model budget entries | Budget-model coverage, not the full 329-provider catalog |
| Recurring/keyless/uncapped providers represented | 58 | Provider presence in recurring forms of the audited budget catalog |
| Free/no-auth discovery entries | 155 | Broader provider metadata; not all have a quantifiable recurring quota |
These values are computed from open-sse/config/freeModelCatalog.ts; see the
Free Tiers Reference for pool deduplication, ToS flags,
discontinued entries, and signup-credit methodology.
The catalog records provider-published terms and project research, but offers can change. Verify the provider's current pricing, quota, privacy policy, and eligibility before use.
Every provider can rate-limit, change models, suspend access, or go offline. Multiple connections improve fallback coverage but do not guarantee an available free route.
Only if the provider's SLA, data handling, limits, and terms meet your production requirements. Critical workloads should have monitored, contractually suitable fallback.
Tradeoffs may include strict limits, waitlists, KYC, credit-card verification, training on prompts, weaker privacy, no SLA, model churn, geographic restrictions, paid overage, or account-policy risk. OmniRoute surfaces the available metadata; you choose what to enable.
auto/cheap to prioritize free/cheap providersNot necessarily. Some providers expose the same model families available through paid routes, but limits, latency, privacy, reliability, and model versions can differ. Use the Free Provider Rankings page as a quality signal and verify the actual model served.
