5 tools that work together

01 · NOTEBOOK-FIRST EXPERIMENTATION
Google ColabFree T4/K80; 12hr; 15GB Drive

Google Colab free tier gives T4 GPUs with 12-24hr sessions — unbeatable for prototyping.

TRY →
  • ▸ML students and learners needing free, zero-setup GPU access.
  • ▸Rapidly prototyping AI models or testing new ideas with free GPUs.
OR SWAP IN
02 · PRO-QUALITY KAGGLE KERNELS
Kaggle Notebooks30 hrs/week GPU; free TPU v3-8

Kaggle gives 30 free GPU hours/week on P100/T4 — pair with Colab for doubled capacity.

TRY →
  • ▸Data scientists needing consistent free P100 GPU compute for weekly tasks.
  • ▸Users training models on Kaggle's vast datasets without credit card hassle.
03 · PERSISTENT GPU DEV BOXES
Lightning AI~35 hrs/month T4; 100GB storage

Lightning AI Studios give free always-on GPU instances — better for training runs that hit Colab's session limits.

TRY →
  • ▸Developers needing a persistent cloud IDE with free T4 GPU for ML projects.
  • ▸PyTorch users seeking a robust, free cloud development environment and storage.
OR SWAP IN
04 · DEMO HOSTING
HF ZeroGPUDynamic H200; PRO: ~25 min/day H200

Hugging Face ZeroGPU gives free H200 access for Spaces — host a demo that others can actually try.

TRY →
  • ▸Developers deploying large model demos on Hugging Face Spaces.
  • ▸Researchers needing powerful GPUs for short, bursty inference/experiments.
OR SWAP IN
05 · FINE-TUNING TOOLKIT

Unsloth makes QLoRA fine-tuning 2x faster and fits bigger models into free-tier GPUs.

TRY →
  • ▸Developers building complex LLM apps needing 700+ integrations and custom logic.
  • ▸Engineers architecting robust RAG, agent, and multi-step prompt chaining workflows.

QUICK START

How to ship it

  1. 1Sign up for Google Colab + Kaggle + Lightning AI + Hugging Face — all free
  2. 2Prototype on Colab, scale training to Kaggle (30hr/week quota)
  3. 3For long runs, move to Lightning Studios (no session timeout)
  4. 4Fine-tune with Unsloth to fit bigger models on free hardware
  5. 5Deploy the final model as a Hugging Face Space with ZeroGPU
⚠ WATCH OUT

Free tiers throttle under heavy use — Colab disconnects idle sessions, Kaggle caps weekly hours. Plan training runs to fit the windows. Model storage is cheap but egress on HF Hub can slow down.
