Q: How can students rent GPUs most affordably?

Tiered spending strategy: ① Free tier (Colab/Kaggle) to validate code; ② Formal experiments on RTX 3090 — 24 GB VRAM, currently the lowest price across all platforms at ¥0.63/hour (Vast.ai (USA)), costing under ¥3 for 4 hours; ③ Reserve RTX 4090 (starting at ¥1.15/hour) for final push. Two key reminders: VRAM is a hard constraint (first estimate your model’s memory requirement), and off-peak/spot instances are cheaper but require saving checkpoints regularly.

Straight answer: Pay-as-you-go scaling: ① Free tier (Colab/Kaggle) to validate your code; ② Production experiments on RTX 3090 — 24GB VRAM, currently the lowest price ¥0.63/hr across all platforms (Vast.ai, US), running for 4 hours costs under ¥3; ③ Reserve RTX 4090 only for sprint phases (starting at ¥1.15/hr). Two key rules: VRAM is a hard requirement (first estimate your model’s memory needs), and off-peak/spot instances are cheaper but require saving checkpoints regularly.

Solution	Current price	Suitable for
Colab Free Tier / Kaggle	free	Validating workflows, coursework, short experiments lasting a few hours
RTX 3090（24GB）	From ¥0.63/hronwards	Inference, QLoRA, SDXL—top value picks for students
RTX 4090（24GB）	From ¥1.15/hronwards	Thesis deadlines, video generation, throughput-intensive workloads

Three rules for students

① Tune your code and verify memory usage on free-tier instances before paying to launch — the most expensive thing is ‘debugging while renting’; ② Log peak VRAM usage and runtime per experiment, then select GPU specs directly from those logs next time; ③ Shut down immediately after use — many platforms continue charging for cloud storage (per GB) even when powered off, and those fees add up.

Where do the prices come from?

This site scrapes publicly listed prices from all platforms every 45 minutes. The prices shown above represent the lowest observed network-wide this period; new-user vouchers on individual platforms often yield further discounts. Always verify final pricing on the platform’s order page.
