Architectural Inference Takeaway
On the local 8GB RTX 4060, FP8 (E4M3) represents the optimal latency-accuracy frontier for interactive serving (73.0 tok/s with only 0.05 PPL delta). For zero-cloud reasoning distillation, AirLLM 70B achieves frontier reasoning (84.2% GSM8K) inside 2,150 MB peak VRAM by offloading sequential layers to local NVMe SSD storage.
