— Plenty of headroomFrequently Asked Questions
- How much VRAM does H2ovl Mississippi 800M need?
H2ovl Mississippi 800M requires 1.8 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 826M × 16 bits ÷ 8 = 1.7 GB
KV Cache + Overhead ≈ 0.1 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
BF161.8 GB- Can I run H2ovl Mississippi 800M on a Mac?
H2ovl Mississippi 800M requires at least 1.8 GB at BF16, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run H2ovl Mississippi 800M locally?
Yes — H2ovl Mississippi 800M can run locally on consumer hardware. At BF16 quantization it needs 1.8 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is H2ovl Mississippi 800M?
At BF16, H2ovl Mississippi 800M can reach ~2637 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~360 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 1.8 × 0.65 = ~2857 tok/s
Estimated speed at BF16 (1.8 GB)
~2857 tok/s~360 tok/s~2857 tok/s~2637 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of H2ovl Mississippi 800M?
At BF16, the download is about 1.65 GB.
- Which GPUs can run H2ovl Mississippi 800M?
