Replicate free credits come as a limited number of free runs on select “Try for Free” models for new users (Replicate doesn’t publicly disclose the exact count). You can start generating immediately, and you do not need a credit card.
Solo devs testing an image pipeline, startup teams building a demo, researchers who just need quick hosted inference without setup. This free tier fits that early “prove it works” phase.
This guide breaks down eligibility, the exact signup steps, what’s included, the rate limits, and how to stretch the free runs before you switch to pay-as-you-go.

What You Actually Get
Replicate gives new users a limited number of free runs on select AI models from its “Try for Free” collection. You sign in with GitHub, Google, or email, and you can run models from the web playground or via the API using an API token (tokens start with r8_). The free tier is meant for experimentation, and once it’s used up you move to pay-as-you-go billing (often per second of compute time, depending on the model). Replicate also hosts thousands of models beyond the free collection, including language models, image and video generation, audio tools, and utility models.
In real terms, this is enough to test prompts, validate output quality, and wire up a basic integration before spending money. You can usually answer the big questions (latency, output style, “does this model fit our use case?”) without setting up billing. The catch is that the free runs are not a monthly benefit, so treat them like a short onboarding budget.
Who Qualifies (and Who Doesn’t)
Eligibility is simple: this is for new users who want to try Replicate before adding a payment method. Replicate positions it as a one-time allowance, and they’re pretty clear that it’s tied to your account identity.
- You need to create an account using GitHub, Google, or email, and then sign in successfully.
- Only one account per person is allowed, tied to your GitHub/Google/email identity.
- No credit card, debit card, or bank transfer is required to sign up and use the free tier.
- A payment method is required only when you exceed the free allowance or want billing-only features (like fine-tuning).
If you’re trying to create multiple accounts to keep getting free runs, don’t count on it. The “one account per person” rule is the quiet deal-breaker for most workaround attempts.
How to Sign Up
Registration is quick, and you can be generating in a few minutes.
- Go to replicate.com.
- Click “Sign in” in the top-right corner.
- Choose your sign-in method: GitHub, Google, or email (no credit card required).
- If you use GitHub or Google, authorize the OAuth connection; if you use email, confirm via the verification email.
- Once logged in, you land on your dashboard with access to the model explorer and your API token.
- To get your API token, click your avatar (top-right), go to “API Tokens,” and copy or create a new token (tokens start with
r8_). - Start running models from the web playground or via the API. Free runs are available immediately on select models.
After signup, the main “gotcha” is simple: the free tier only applies to select “Try for Free” models, and the set can rotate over time. If you pick a model outside that collection, Replicate will push you toward setting up billing.
What the Credits Cover
Your free runs apply to models in Replicate’s curated “Try for Free” collection, which includes popular image models, video tools, and restoration/upscaling utilities. Outside that collection, you can still access the broader catalog, but you’ll be on pay-as-you-go pricing (per second of compute, per token, or per output depending on the model).
| Service / Feature | What It Does | Included? |
|---|---|---|
| Try for Free image models | Text-to-image via curated models like Imagen and FLUX. | ✓ |
| Try for Free video tools | Generate, reframe, or upscale video via select models. | ✓ |
| API access (REST + client libs) | Run hosted inference via API token and official SDKs. | ✓ |
| Fine-tuning (e.g., FLUX training) | Create a custom model by training with your images. | ✗ |
Notable exclusions: fine-tuning requires billing to be set up, and the full model catalog (including many LLMs and paid image/video models) is not covered by the free allowance unless they’re in the “Try for Free” collection.
Limitations to Know About
Every free program has catches. Replicate’s are reasonable, but you should know them before you build anything “real” on top of the free tier.
- The exact number of free runs is not publicly disclosed, so you cannot plan around a published quota.
- There is no monthly free tier reset; the free allowance is a one-time experimentation budget.
- Without billing, rate limits are tight: 1 request per second, with a max of 6 requests per minute.
- The “Try for Free” model collection changes over time, so a model you tested may rotate out later.
When your free runs are exhausted, you switch to pay-as-you-go. At that point, you’ll need to add a payment method (credit card, debit card, or bank transfer) to keep running models, and you’ll be billed based on the model’s pricing (often per second of compute time). Replicate also notes that failed runs are never charged, which helps reduce “oops” costs when you’re iterating.
Have Unused Replicate Credits?
Sometimes teams buy prepaid credit, then usage doesn’t pan out. Or the project ships and the balance just sits there. If you have Replicate credit you won’t use, listing it can be better than letting it gather dust (or expire under the terms you bought it with). AI Credit Mart lets you sell unused credits to other builders at a discount, so at least some of that budget comes back.
Need More Replicate Credits?
Once the free runs run out, paying retail is not your only option. AI Credit Mart has discounted Replicate credits from companies with surplus allocations. Discounts typically land around 30–70% below face value, which can stretch a prototype budget a lot further.
Tips for Getting the Most Out of Your Credits
- Start in the web playground to evaluate outputs quickly before you spend time on API integration.
- Stick to models in the “Try for Free” collection while you’re still on the free tier, because paid models will push you toward billing.
- Keep your API tokens private (they’re 40-character strings starting with
r8_) and store them in environment variables instead of hardcoding. - Check each model’s license on its model card before using outputs commercially, even if the model is free to run.
- Plan for deletion of API prediction parameters, outputs, and logs after about 1 hour by default, so save outputs you care about.
Frequently Asked Questions
Replicate doesn’t publish an exact dollar value or a confirmed “X generations” number for the free runs. Practically, the value is whatever you can run inside the “Try for Free” collection until your allowance runs out, which is usually enough to test a few models (image, video, upscaling) and decide what you want to pay for. Once you move to paid usage, some popular examples from Replicate’s pricing include FLUX 1.1 Pro at about $0.04 per image and Ideogram V3 at about $0.09 per image. For LLMs, pricing can be token-based (for example, Claude 3.7 Sonnet is listed at $3.00/M input tokens and $15.00/M output tokens).
No.
They don’t “last” on a timer so much as they get used up: it’s a one-time allowance with no monthly reset, and you keep accessing it until the free runs are exhausted.
Yes. If you have Replicate 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 Replicate credits available from companies with surplus allocations. Prices are typically 30-70% below retail.
For the free tier, there’s no published expiration window; you simply switch to pay-as-you-go once the free allowance is exhausted.
Without billing, Replicate limits you to 1 request per second and a maximum of 6 requests per minute. With billing enabled, limits jump to about 600 predictions per minute and 3,000 other API calls per minute, which is the difference between “toy demo” and “real integration.” Replicate also notes that rate limits tighten as your credit balance approaches zero to prevent overspending, so if you’re seeing throttling on a paid account that’s a clue to check your balance.
Yes. For API predictions, input parameters, output values, and logs are automatically deleted after about 1 hour by default, so you need to save outputs yourself if you want to keep them.
Replicate’s free tier is a solid on-ramp: no card, instant access, and enough free runs to evaluate real models. Use it to pick your stack fast, then either pay-as-you-go or source discounted Replicate credits if you want to keep costs down.
