Conclusion first:Light users: ¥30–60/month; mid-tier creators: ¥150–300/month; heavy-duty studios: ¥800+/month. Let’s calculate.
What GPU is required for SD?
SD 1.5/SDXL requires ≥8GB VRAM; RTX 3090 delivers best value. Flux.1 needs ≥16GB—RTX 4090 recommended. Video generation (Wan/Hunyuan) starts at 24GB; RTX 4090 is the baseline.

Three-Tier Usage Billing (RTX 4090, Pay-as-you-go)
Light usage（1 hour per day, casual use on weekends）: 1h × 30 days × ¥1.5 ≈ $45/month。moderate（3 hours per day, for freelance work or content creation）: 3h × 30 × ¥1.5 ≈ $135/month。heavy-duty（8 hours per day, studio-scale production）: 8h × 30 × ¥1.5 ≈ $360/monthAt this scale, you should negotiate a monthly plan (typically saving 25% or more).
Three immediate money-saving actions
① Batch image generation jobs together and shut down immediately after completion—pay-as-you-go platforms stop charging when GPU is powered off; ② Use RTX 3090 instead of RTX 4090 where possible (up to ~30% cheaper for SDXL workloads); ③ Run interruptible batch jobs on spot instances for up to 50% extra savings—but enable auto-save.
