1. 2026 Pricing & Rate Table
| Plan / Item | 2026 Rate & Included Quota |
|---|---|
| FP16 / BF16 (16-bit) | 2 bytes per parameter (70B model ≈ 140 GB weights + KV cache) |
| FP8 / INT8 (8-bit) | ~1.05 bytes per parameter (70B model ≈ 73.5 GB weights + KV cache) |
| INT4 / AWQ / GGUF (4-bit) | ~0.58 bytes per parameter (70B model ≈ 40.6 GB weights + KV cache) |
| KV Cache & CUDA Overhead | Adds 10% to 35%+ extra VRAM based on context length and batch size |
2. Easy Ways to Lower Your Monthly Cost
- For a quick 4-bit estimate with an 8K context window, multiply the model size in billions by 0.7 (70B × 0.7 ≈ 49 GB VRAM).
- A 70B model in 4-bit fits comfortably on two 24GB GPUs (48GB total) or a single 80GB A100/H100 GPU.
- Long context windows (32K to 128K) increase KV cache memory fast—turn on KV cache quantization in vLLM to save memory.
- Claim free GPU credits from Modal, Vultr, or DigitalOcean on StartupCreditHub before renting servers at full price.
