Notes
Q2_K
RDNA 4 card with improving ROCm support; Vulkan remains the safer default in llama.cpp. Q2_K needs ~115GB and relies on offloading on this card. MoE models still have to load the full expert pool into memory.
About DeepSeek R1
DeepSeek R1 (671B) is a reasoning, coding, ai coding, multi-purpose model. DeepSeek's reasoning-focused model. Same MoE architecture as V3 (671B total, ~37B active per token). Excels at chain-of-thought reasoning, math, and complex code. Requires the same massive hardware as V3: multi-GPU or 128GB+ Apple Silicon at heavy quantization. For most home users, the distilled versions (7B, 32B) are more practical.
