Frequently Asked Questions
How much VRAM does Overfitter 1.0 need?
Overfitter 1.0 requires 0.4 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 50M × 16 bits ÷ 8 = 0.1 GB
KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
KV Cache + Overhead ≈ 0.3 GB (at full 4K context)
VRAM usage by quantization
Can I run Overfitter 1.0 on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Overfitter 1.0. Apple Silicon uses unified memory, so the model shares RAM with the system. At BF16 you need at least 0.4 GB of usable unified memory (RAM minus macOS overhead).
Can I run Overfitter 1.0 locally?
Yes — Overfitter 1.0 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Overfitter 1.0?
At BF16, Overfitter 1.0 can reach ~11429 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~1560 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 ÷ 0.42 × 0.65 = ~12381 tok/s
Estimated speed at BF16 (0.4 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Overfitter 1.0?
At BF16, the download is about 0.10 GB.
Which GPUs can run Overfitter 1.0?
52 consumer GPUs can run Overfitter 1.0 at BF16. Top options include AMD Radeon RX 6700 XT, AMD Radeon RX 6800, AMD Radeon RX 6800 XT. 52 GPUs have plenty of headroom for comfortable inference.
Which devices can run Overfitter 1.0?
163 devices with unified memory can run Overfitter 1.0 at BF16 (0.4 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
