The best free GPU tier is worth about $19 a month at rental rates, and eight platforms give a real GPU with no credit card. Six of them cap free usage by the month, and we priced those at the cheapest current on-demand rate for each GPU in our cloud GPU pricing data.
Each bar is the rental cost of the same GPU time, calculated as a platform’s free monthly GPU hours multiplied by the cheapest hourly rate for that GPU.
For example, Lightning AI’s 80 free GPU-hours a month would cost about $12 to rent the same GPU on-demand at the cheapest provider. Quotas that a platform does not publish are estimated.
GPU and memory by platform
Usage limits by platform
Platforms with the most memory tend to give the least time on them.
Three kinds of free GPU access
The platforms above provide a GPU at zero cost with no credit card, on either a standing tier or a monthly allowance. The trade is time limits, weekly quotas, shared hardware, and a mid-range GPU, not a paywall. Google Colab, Kaggle, Hugging Face ZeroGPU, Saturn Cloud, Lightning AI, Paperspace Gradient, and Intel Tiber AI Cloud all work this way.
The hyperscalers advertise a different thing. Google Cloud’s “$300”, Azure’s “$200”, and the AWS and Oracle equivalents are trial credits. They need a credit card that expires in 30 to 90 days and blocks GPU access on the trial itself. Google Cloud and Azure require converting to a paid, billable account before any GPU runs, and new accounts are often refused GPU quota outright. These suit a short burst when a card is already on file, not a standing free GPU.
A third group covers startup and research programs such as NVIDIA Inception, Nebius AI Lift, DigitalOcean Hatch, and Lambda’s research grants. They hand out $5,000 to $150,000 in credits, but behind an application, and eligibility is limited to incorporated startups or affiliated researchers.
Two claims that circulate are wrong. Oracle’s “always-free” tier is CPU-only, so the “free A10 GPU” some lists mention does not exist. And a free inference API (Groq, Cerebras, Google AI Studio, Cloudflare Workers AI) returns tokens from a hosted model, not a GPU for running custom code.
Free GPU platforms
Google Colab
Google Colaboratory runs Python notebooks in the browser and assigns an NVIDIA T4 (16 GB VRAM) on its free tier.1 The older K80 is retired, and premium L4 or A100 GPUs are Pro and Pro+ features. A session lasts up to 12 hours but disconnects after about 90 minutes idle or when the tab closes, because background execution is a Pro+ feature. The weekly GPU allowance is not published and shifts with demand, with recent estimates near 15 to 30 GPU-hours, and at peak times, a free session can drop to CPU. No credit card is needed. System RAM is about 12.7 GB, and the disk is ephemeral, so most people mount Google Drive to keep files.
Kaggle
Kaggle, a Google subsidiary, pairs free notebooks with tens of thousands of public datasets. The free tier offers one P100 (16 GB) or two T4s (32 GB combined), plus a TPU v5e-8 that replaced the older v3-8 in 2025.2 The weekly allowance is about 30 GPU-hours, a GPU session runs up to 12 hours, and a TPU session up to 9.3 Storage is 20 GB and persistent, with no credit card.
Hugging Face ZeroGPU
ZeroGPU targets a different job than the others. It exists to publish a model demo rather than train one, and it attaches an NVIDIA RTX Pro 6000 Blackwell (48 GB by default, 96 GB for the larger size) with no credit card. A free account gets about 5 minutes of GPU per day (2 minutes signed out, 40 minutes on PRO), and the GPU runs inside a Gradio app’s @spaces.GPU functions for about 60 seconds per call.4 It is inference and demo infrastructure, so it does not stand in for a training notebook, and regular Spaces hardware is CPU-only.
Saturn Cloud
Saturn Cloud’s Hosted Free tier is the closest new entrant to Colab and Kaggle for everyday notebooks. It gives a single T4-class GPU (up to 16 GB) on a recurring free tier with no credit card.5 Saturn no longer publishes the monthly free-hour figure, and past numbers range from about 30 hours upward, so treat the allowance as approximate.
Lightning AI
Lightning AI provides a persistent cloud IDE with 15 free credits per month, which it equates to about 80 GPU-hours on interruptible machines.6 That figure holds for cheap GPUs and shrinks fast on a high-end card. Free Studios run continuously with a manual restart every 4 hours, and the GPU menu spans T4 and L4 up to L40S, A100, and H200 on interruptible capacity. Storage is 50 GB, with no credit card.
Paperspace Gradient
Paperspace, now part of DigitalOcean, keeps a free GPU notebook tier. It runs an NVIDIA M4000 (8 GB) with a 6-hour auto-shutdown, unlimited restarts, and one concurrent free notebook.7 Free instances need no credit card, while paid instances do. Free-tier notebooks are public, so they are a poor fit for sensitive data, and the standalone platform is being folded into DigitalOcean.
Intel Tiber AI Cloud
For non-NVIDIA work, Intel Tiber AI Cloud runs free JupyterLab and training notebooks on Intel Gaudi accelerators and Intel Data Center GPU Max, with no credit card.8 The stack is Intel oneAPI and the PyTorch XPU backend rather than CUDA, so CUDA-only code needs porting, and sessions are batch and shared rather than always-on.
Amazon SageMaker Studio Lab
Studio Lab is a standalone free notebook service with an NVIDIA T4 (4 hours per session, 4 hours per 24-hour period), 15 GB of storage, and no AWS account or credit card. One date matters. AWS closes new-customer access on July 30, 2026.9 Existing accounts continue with no announced end date, but new users should register before then or pick another option, since AWS’s suggested replacement, SageMaker Studio’s free tier, is a CPU-only ml.t3.medium rather than a T4.
Free credits and trials
Trial credits are a temporary budget, not a standing GPU, and each one needs a card and expires. Google Cloud gives $300 for 90 days, but the non-billable trial cannot attach a GPU until the account converts to paid billing. Azure gives $200 for 30 days, with GPU families off the free account and quota commonly refused on new accounts. AWS grants up to about $200 over roughly 6 months, on a CPU-only always-free tier with a default GPU quota of zero. Oracle’s $300 for 30 days reaches a GPU, though its Always Free tier does not. Modal sits between these and a free tier. It gives $30 per month in recurring credits, no card to start, on serverless T4 through H100 hardware, which works out to roughly 50 hours of a T4 or under 8 hours of an H100 before the monthly budget resets.10
Startup and research grants
Incorporated startups and affiliated researchers can apply for packages of $5,000 to $150,000. NVIDIA Inception routes to partner credits such as Nebius AI Lift (up to $150k) and AWS Activate (up to $100k) plus discounted DGX Cloud. DigitalOcean Hatch offers up to $100k for early-stage startups, and Lambda’s research grants give up to $5k to university-affiliated AI teams. Cloud programs from OVHcloud (€100k), Scaleway (€36k), and Alibaba ($120k) work the same way, against an application rather than a sign-up.
Limitations of free cloud GPUs
Free GPU access comes with three real constraints, and knowing them upfront saves a wasted afternoon.
The first is time. Every free tier caps how long a single session runs, and most add a weekly or monthly quota on top, so a long training job can stop when the quota resets rather than when the model is done. Idle sessions also disconnect on their own after a short window of inactivity, which makes unattended overnight runs unreliable because background execution is a paid feature on almost every platform.
The second is shared hardware. A free GPU is pooled across many users, so a run competes for it. Throughput drops during busy hours, sessions wait in a queue, and the GPU is not guaranteed on demand. Google Colab, for example, can hand a free session a CPU instead of a GPU when demand is high.
The third is the ceiling on model size. Free tiers hand out a mid-range GPU, a single T4, P100, or M4000 with 8 to 16 GB of memory, which cannot hold a large model in full precision. Running or fine-tuning one means quantizing the weights, checkpointing gradients, or sharding across the limited memory. Storage caps and restricted outbound network access are smaller versions of the same problem.
Add as preferred sourceBest practices for free cloud GPUs
A few habits stretch a free tier. Saving work often, monitoring the remaining quota, and keeping a session active during a job all help, since an idle disconnect loses in-memory state. Preparing and debugging code locally before spending GPU time, loading data efficiently, and handling errors keeps a crash near the time limit from costing the whole run. Choosing the platform by task and checking framework and community support comes before committing to one.
When to upgrade to paid services
A paid GPU makes sense when the work needs guaranteed access, a card larger than the free tiers offer, team collaboration, or a session longer than a free window allows. Our guides to cloud GPU providers and cloud GPU pricing compare paid options and costs.

FAQs
The standing free tiers, Google Colab, Kaggle, Hugging Face ZeroGPU, Saturn Cloud, Lightning AI, Paperspace Gradient, and Intel Tiber AI Cloud, need no card. The trial credits from Google Cloud, Azure, AWS, and Oracle do require one.
Small models and fine-tuning, yes. Free tiers give one mid-range GPU, a T4, P100, or M4000 with 8 to 16 GB of VRAM, under session and weekly-quota limits, so large models need quantization, sharding, or a paid GPU.
It is free for now, but AWS closes new sign-ups on July 30, 2026. Existing accounts continue, and new users should pick another option or register before the deadline.
