You get about $0.10/month in Hugging Face free credits for the Inference API (yes, it’s tiny, and yes, it can still be useful). It’s designed for quick experiments with Hugging Face Inference Providers, which can route your requests to 200+ models across 18+ inference partners.
Developers testing an OpenAI-compatible endpoint, startup teams validating model choices before committing to a vendor, and students poking at embeddings or image generation will all get something out of it. Just don’t treat it like a real budget. It’s more like a “does this work?” check.
This guide covers eligibility, a step-by-step signup, what the credits actually cover, the gotchas (402 errors), and a few ways to stretch the free tier.

What You Actually Get
The Free Inference API Credits apply to Hugging Face Inference Providers, which is a proxy layer between your app and multiple AI providers (Groq, Together AI, SambaNova, Fireworks, Replicate, and others). You make requests using a single Hugging Face token, and Hugging Face routes them to an available provider. The endpoint is OpenAI-compatible for chat completions, which means you can often swap https://router.huggingface.co/v1 in as your base URL with an OpenAI SDK.
In real terms, $0.10 goes fast. Hugging Face itself warns it might cover a few LLM chat completions or roughly one image generation, depending on which model/provider you hit and how long it runs. Think of it as a routing and integration trial: confirm your auth works, confirm responses look right, then decide whether you want PRO, pay-as-you-go (PRO/Enterprise only), or “bring your own key.”
Who Qualifies (and Who Doesn’t)
Eligibility is refreshingly simple: if you have a Hugging Face account, you get the monthly free inference credits. There’s no application, no review, and no waiting period.
- You need a Hugging Face user account created via email signup or an OAuth provider.
- Your email address must be confirmed before you generate the token you’ll use for API calls.
- You must create a fine-grained access token with permission to “Make calls to Inference Providers.”
- No credit card is required, including after you hit the free monthly limit.
The main “doesn’t qualify” scenario is more practical than formal: if you need uninterrupted usage after the free credits run out, the free tier will not work for you because it hard-stops at the limit.
How to Sign Up
Signup is quick, and access is instant once your token is set.
- Go to huggingface.co/join.
- Sign up with email or sign in with Google, GitHub, or another OAuth provider.
- Confirm your email address.
- Go to Token Settings and create a fine-grained token with the “Make calls to Inference Providers” permission.
- Done. You can use the Inference API immediately with your ~$0.10/month free credits.
After that, calls made through the routed Hugging Face mode will draw down your monthly credits automatically. Unused credits don’t roll over, so there’s no reason to “save” them for later in the month.
What the Credits Cover
The free credits apply when you let Hugging Face route the request (the default “Routed by Hugging Face” mode). In that mode, Hugging Face proxies the call to a provider and applies your monthly credits to the provider-rate billing.
| Service / Feature | What It Does | Included? |
|---|---|---|
| Inference Providers (routed) | Unified API routing to multiple inference partners | ✓ |
| OpenAI-compatible endpoint | Use OpenAI SDK with router.huggingface.co/v1 for chat | Partial |
| Model catalog access | Choose from 200+ models across 18+ providers | ✓ |
| Custom Provider Key mode | Use your own provider API key (billed by provider) | ✗ |
Notable exclusions: the OpenAI-compatible endpoint only supports chat completions, so for images, embeddings, or speech tasks you’ll want the native Hugging Face SDKs or direct HTTP calls. Also, if you switch to “Custom Provider Key,” Hugging Face credits don’t apply because the provider bills you directly.
Limitations to Know About
Every free program has catches. This one is honest about them, which I appreciate.
- The free tier is about $0.10 per month, and it can be exhausted by a handful of calls.
- Unused credits reset monthly and do not roll over, even if you barely touched them.
- Free users cannot continue past the monthly limit, because there is no pay-as-you-go on the free plan.
- There’s no SLA on the free tier, so don’t expect guaranteed uptime or latency.
When credits run out, requests fail with a 402 Payment Required error and that’s it for the month on the free plan. Your account does not “close,” but your routed inference usage stops until the monthly reset (or until you upgrade to PRO/Enterprise, which unlocks pay-as-you-go after credits).
Have Unused Hugging Face Credits?
Honestly, most people won’t accumulate surplus on this specific free tier because it’s so small. But Hugging Face credits also show up through team setups, enterprise arrangements, or “we bought PRO seats and didn’t use them” situations, and those can go unused. If you have credits you won’t burn before they reset or expire, you can turn them into cash instead of letting them go to waste. AI Credit Mart is built for that, and listings typically sell well below face value.
Need More Hugging Face Credits?
Once you hit the 402 wall, you have a few options: upgrade to PRO, bring your own provider key, or source discounted credits. AI Credit Mart has Hugging Face credits offered by teams that can’t use their allocations. Prices typically land around 30–70% below retail, so you can keep building without paying full freight.
Tips for Getting the Most Out of Your Credits
- Treat the $0.10 as a trial for integration and routing, not something you can build production on.
- Start with short prompts and minimal output tokens, because a few long generations can drain the monthly allotment quickly.
- Use provider selection controls when you can: the “:cheapest” suffix is meant to bias toward lower-cost routes.
- If you already have accounts with providers like Groq, Together AI, or SambaNova, consider “bring your own key” so you don’t consume Hugging Face credits.
- Track usage and billing in settings so you’re not guessing where the credits went: huggingface.co/settings/billing.
Frequently Asked Questions
They’re worth about $0.10 per month in routed inference, which is usually just a few short chat completions (or roughly one image generation) before you hit the limit.
No.
They reset monthly, and unused credits do not roll over to the next month.
Yes. If you have Hugging Face credits you won’t use before they expire, you can list them on AI Credit Mart and sell them at up to 70% of face value. Companies regularly list surplus credits from startup programs and enterprise agreements.
AI Credit Mart has discounted Hugging Face credits available from companies with surplus allocations. Prices are typically 30-70% below retail.
On the free plan, you hit a hard stop: once your monthly credits are used up, routed API calls return a 402 Payment Required error until the next monthly reset. There’s no pay-as-you-go fallback for free users. If you upgrade to PRO, you get $2/month in credits and can continue with pay-as-you-go billing after the credits run out. Hugging Face bills at provider rates with zero markup, so you’re not paying an extra “router tax.”
No. In “Custom Provider Key” mode, the provider bills you directly and Hugging Face credits don’t apply.
Yes, for chat completions: point your client at the OpenAI-compatible base URL (https://router.huggingface.co/v1) and authenticate with your Hugging Face token that has Inference Providers permission.
Hugging Face’s free inference credits are small, but the routing layer is genuinely handy for quick model/provider evaluation. Use the free tier to validate your setup, then upgrade or source discounted credits if you need to keep shipping.
